Structures in the image matching the grey values are highlighted. Unmapped grey values are shown transparent. Specific structures become more clearly visible. Various algorithms e. Surface representations can also be applied to improve the visualization of certain image structures. General and integration requirements have been evaluated on public information provided by the developers or vendors.

In contrast, viewing functionality has been investigated by the authors themselves. Aiming at reproducibility, the criteria have been verified using public available datasets. In this data set, JPEG is used as transfer syntax. Since, this caused issues in some viewers, another dataset has been included. The data set includes a series with CT images.

The evaluation of web applications is based on demo systems. Since the demo applications usually do not allow import of data sets, the criteria have been investigated using already available data sets. Sixteen of twenty-one projects of Liao et al. The viewer Amide and FPImage seems to be no longer maintained, since no version running on our Bit Windows system was available.

Out of the 28 projects, 16 tools are licensed as open source, 8 as free, and 4 as commercial products. In addition, 7 tools also provide GUIs for mobile devices. WADO is provided by 7 and parameter transfer by 5 viewers. Only parameter transfer seems to not be possible with both viewers.

A total of 13 image viewing criteria have been included. Eight requirements for 2D and five requirements for 3D exist. On the average, a total of 5. On the other hand, for web-based viewers, 3. With 5. Focusing on research, flexible low-budget software solutions are advantageous, in particular concerning investigator initiated trials IIT.

Here, open source tools have been recommended over free or commercial products [ 18 ]. As our survey shows, open source tools are on a par with commercial software. In fact, they reached partly better scores, which is also in line with the findings of Horii [ 8 ]. Our survey does not yield an overall best candidate. There is no viewer fulfilling all criteria we have defined.

Each application has its own focus and requires particular features. Thus, significance is achieved by comparing the viewers with respect to use cases. Decentral viewing of image data within the eCRF optimally supports the workflow of the study personnel [ 5 ]. Since eCRFs are, today, usually offered via web, only web- or platform-independent viewers can be integrated. Data and context integration is necessary, which can be provided by WADO and parameter transfer, respectively.

Oviyam and Weasis are the only web-based and platform-independent candidates, which are utilized with WADO and parameter transfer interfaces. Both projects are open source. However, Weasis slightly beats Oviyam regarding 2D image viewing by two criteria.

On the other hand, Oviyam could be extended by iOviyam for support of mobile devices. However, we recommended Weasis as optimal viewer for this use case. In our opinion, pseudo-coloring and annotations are yet more important than mobile device support. In the advanced viewing use case, 3D volume visualization is needed. However, the 3D performance of web browsers is—at least up to today—still restricted. Hence, web applications are not really suitable for 3D rendering.

This is also underlined by the low 3D imaging score of web tools in our survey. Standalone or platform independent viewers are more preferable. Each tool fulfills all 3D viewing criteria. This might be useful during viewing of single 3D slices. Of course, there are other application scenarios other than the three we defined.

Recently, Lo Presti et al. For this special-use case, they identified Synapse 3D and OsiriX as optimal. Although their results are based on different evaluation criterions than those we have used for the advanced viewing-use case, OsiriX reached the highest score in both evaluations. As our evaluation shows, rich functionality and suitable interfaces can be also found in the open source field of DICOM viewer software. Excellent software must not always be invaluable and is also available for low-budget research, e.

However, each tool has its strengths and weaknesses; an all-rounder solution does not exist. However, this work suggests optimal candidates of the large pool of DICOM tools for common applications. As we have shown in our previous work, a good choice of components simplifies the build-up of a suitable system architecture [ 5 ]. National Center for Biotechnology Information , U.

Any serial images can be used to make a reconstruction. Using SURFdriver's new texture rendering, it's easy to make professional images without any additional software.

You can even view objects in stereoscopic 3D with the included 3D glasses! SURFdriver's interface makes your reconstructions easy! Powerful tools like the Magic Wand and Object Tracing make contouring fast and easy. And the smoothing function means that even roughly-traced objects can come out looking clean and professional. Physiologic-based research has traditionally involved highly invasive techniques which may alter the very function being studied.

Since the first dynamic volumetric studies were done in the early 's on the Dynamic Spatial Reconstructor DSR , there has been a surge of interest in volumetric and dynamic imaging using a number of tomographic techniques. The windowing environment allows execution of multiple processes at once.

Available programs include: orthogonal sectioning, oblique sectioning, volume rendering, surface rendering, region of interest analysis, conventional cardiac mechanics analysis, homogeneous strain analysis, tissue blood flow evaluation, interactive image segmentation and editing, algebraic image manipulation, and more. An emphasis has been placed upon image quantitation for the purpose of physiological evaluation. Vis5D is a software system for visualizing data made by numerical weather models and similar sources.

Vis5D works on data in the form of a five- dimensional rectangle. That is, the data are real numbers at each point of a "grid" which spans three space dimensions, one time dimension and a dimension for enumerating multiple physical variables. Of course, Vis5D works perfectly well on data sets with only one variable, one time step i.

However, your data grids should have at least two rows and columns. The major new feature of Vis5D version 5. Data sets that are overlaid are aligned in space and time. In the spread sheet style, multiple displays can be linked. Once linked, the time steps from all data sets are merged and the controls of the linked displays are synchronized.

The Vis5D system includes the vis5d visualization program, several programs for managing and analyzing five-dimensional data grids, and instructions and sample source code for converting your data into its file format. We have included the Vis5D source code so you can modify it or write new programs.

We have also included sample data sets from the LAMPS model and from Bob Schlesinger's thunderstorm model, so you can work through our examples. The MK Toolkit provides programmers with an easy, object-oriented way to develop complex 3D interactive applications. A 3D interactive application involves the complex interplay of three kinds of objects: volumetric objects, virtual tools and 3D widgets. The user controls directly the virtual tools, which in turn operate on volumetric objects and on 3D widgets contained in the virtual tool panel.

The 3D widgets trigger the activation of virtual tools and control the parameters of the application. Most importantly, the MK Toolkit provides predefined virtual tools volume cutter, voxel eraser, rotator, contour and tube segmentation tools, etc , predefined 3D widgets slider, buttons, curve controls , so that programmers can draw from this pool resource and quickly start building applications.

All this is seamlessly integrated in the Dextroscope: the virtual tool panel is an integral part of the 3D environment and displayed and interacted in 3D space.

The volume rendering module provides multimodality fusion so that overlapping data sets can be seen simultaneously as a single object , supports two-byte per voxel data to preserve maximum resolution, and simultaneous colors from a palette of 16 million. Summarizing, the MK Toolkit offers two unique features:. This application provides most of the generic virtual tools needed to work with volumes: it enables loading, manual inspection of multimodal data, segmentation and final storage on disk.

VizPack helps all customers that do not require highly customized applications for their problem solving due to the nature of their work process. The VolumePro architecture employs a ray-casting algorithm, which shoots rays through a volume object from each pixel in the image.

It tri-linearly interpolates samples along each ray, provides complex shading calculations and color assignments at the sample points, which are then accumulated into the final pixel colors. The goal of the VolumePro SDK is to bundle all the software and documentation into a single complete package that will allow application developers a one stop shopping experience.

VolView provides a multi-resolution, multi-processing ray casting method for accurate rendering, or can be used in conjunction with 2D hardware texture mapping or the VolumePro volume rendering hardware to obtain interactive rendering rates on low-cost platforms for a variety of application areas including biomedical visualization, simulation, and volume graphics.

VolView 1. Preset transfer functions and material properties. Easy-to-use transfer function and material editors. Powerful cropping and cut plane tools. Orthogonal and oblique reformat views. Annotation including text, axes, and scalar bars. Scripting capabilities to automate repeated tasks, create animation sequences, and access the underlying visualization system - The Visualization Toolkit VTK.

VolVis is a volume visualization system that unites numerous visualization methods within a comprehensive visualization system, providing a flexible tool for the scientist and engineer as well as the visualization developer and researcher.

Diversity: VolVis supplies a wide range of functionality with numerous methods provided within each functional component. For example, VolVis provides various projection methods including ray casting, ray tracing, radiosity, Marching Cubes, and splatting. Ease of use: The VolVis user interface is organized into functional components, providing an easy to use visualization system. One advantage of this approach over data-flow systems is that the user does not have to learn how to link numerous modules in order to perform a task.

Extensibility: The structure of the VolVis system is designed to allow a visualization programmer to easily add new representations and algorithms. For this purpose, an extensible and hierarchical abstract model was developed [Avila et al. Freely available: The high cost of most visualization systems and difficulties in obtaining their source code often lead researchers to write their own tools for specific visualization tasks.

VolVis is freely available as source code to not-for-profit organizations. There is a small fee for for-profit organizations. Currently, we are doing research and development to extend VolVis funcionality, usability and stability.

Lots of new features are expected to be incorporated within the next year: like support for irregular grids, parallel rendering, and flow visualization. It consists of three main components: visualisation module for high quality rendering segmentation module a semantic network knowledge base system The development of a first version started in The present program system lines of C code incorporates the results of ten years of research and development work.

VoxelView is a powerful, comprehensive and interactive volume rendering program that manipulates and displays volume data from a wide variety of medical imaging sources. With VoxelView, users can visualize, analyze and manipulate large and complex 3D data sets on general-purpose workstations with industry-leading speed and efficiency.

An Important element of Vital Images' product line, VoxelView allows the user to manage the scientific data workflow from pre-processing to presentation. Its advanced volume rendering algorithms provide users with a high-speed volume visualization and analysis system that is highly intuitive and delivers instant visual feedback. VoxelView is easy to learn, yet very sophisticated.

Users can quickly adjust the displayed image with VoxelView's simple-to-operate, mouse-driven user interface. Every function of the program can be accessed by simply pointing to and clicking on menu items. In addition, VoxelView is completely modularized so each function runs independently; giving users increased flexibility, and permitting developers to interface with other software programs.

The design and implementation of the library has been strongly influenced by object-oriented principles. This means it is much easier to create useful graphics and visualization applications.

In fact, using the interpreted languages Tcl or Python with Tk, and even Java with its GUI class libraries, it is possible to build useful applications really, really fast. Finally, the software is a true visualization system, it doesn't just let you visualize geometry. VTK supports a wide variety of visualization algorithms including scalar, vector, tensor, texture, and volumetric methods; and advanced modeling techniques like implicit modelling, polygon reduction, mesh smoothing, cutting, contouring, and Delaunay triangulation.

Our goal is to make the software easy enough for any computer literate person to use. Although VTK is freely available, commercial support is available from.

Dozens of other companies, ranging from large US Government research labs to small firms selling custom postprocessors, use VTK. Also, VTK is widely used in academia for research and in courses on visualization and graphics. The maximum entropy based 3D deconvolution generates the best quality image restoration for microscopy imaging applications. If you are a power user, the 3DBasic scripting language will let you create your own Basic-like sophisticated programs using 3D-DOCTOR's advanced imaging and rendering functions quickly.

The 3D Slicer is freely available, open-source software for visualization, registration, segmentation, and quantification of medical data. The 3D Slicer is a software tool for:. The 3D Slicer uniquely integrates several facets of image-guided medicine into a single environment. It provides capabilities for automatic registration aligning data sets , semi-automatic segmentation extracting structures such as vessels and tumors from the data , generation of 3D surface models for viewing the segmented structures , 3D visualization, and quantitative analysis measuring distances, angles, surface areas, and volumes of various medical scans.

The image to the left was created by segmenting an anatomical MR scan to form 3D surface models of the skin and tumor green. A review on freely downloadable software for offline analysis of structural and functional neuroimaging data can be found in a future issue of this journal. These can prove to be effective alternatives to commercially available programs and radiologists can implement these solutions to augment their clinical practice, taking into consideration their individual requirements as well as the software's functional capabilities and limitations.

For the preparation of this article, software for viewing and processing DICOM image data, that can be downloaded free of cost, was evaluated on a notebook computer with a 1. As on 25 Oct , most browsers were available as a simple download link, while a few required online registrations to unlock certain features. All programs were simple to install. A few programs required the installation of additional software such as Java Runtime Environment that is available on the web.

Softwares that require compilation before use, handle proprietary and non-DICOM medical image formats, and run on other operating systems have been excluded from the review. All softwares were evaluated independently by an experienced radiologist and a trainee radiologist for features such as ease of installation, range of tools available, and the relative ease of operation. Though some browsers were able to process non-DICOM image formats as well as proprietary image formats, these capabilities were ignored for the purpose of this review.

Though every attempt has been made to keep the information about these browsers accurate and up-to-date, variations in host computer specifications and periodic software updates may cause inconsistent browser functionality. Readers are urged to study the relevant up-to-date documentation regarding these browsers.
