Web3D DICOM Viewer¶
Web3D DICOM Viewer creates a 3D model of a body part based on the set of plane images (DICOM, NIfTI, etc. file formats) and shows 2D/3D views via a web browser without any installations. Web3D DICOM Viewer will please you with speed and convenience in comparison even with desktop analogues. Fast smooth 3D visualization based on unique rendering algorithms developed at EPAM, which don’t require data preprocessing, thus visualization starts right after the data loading.
EPAM DICOM 3D Viewer is going to be a free opensource software.

- No installation on a user computer required.
- Compatibility with all popular desktop OSs.
Simple User Interface¶
The functionality depends on the selected visualization mode (2D or 3D), and in case of 3D mode on the selected visualization method. There is a 3D visualization mode with a volume render method on the screenshot below. In this case the interface provides the ability to select areas of interest inside the volume, brightness and contrast adjustment, as well as the ability to use the near clipping plane position.
This method suits for bones, skin surface and segmented areas visualization. The base of this method is a search of the intersection points between the rays corresponding to pixels and the isosurface. The user selects the level of the isosurface and the near clipping plane position with sliders.
This method suits for studying the initial data volume and the soft tissues visualization. It allows to choose an area of the interest by specifying the transfer function, which assigns the amount of the initial data to the amount of the transparency and color. To simplify the transfer function, the user uses a function in the application, which he can define by adjusting three parameters (a, b and c) with sliders. The function is nonzero only if the intensity i satisfies the conditions a < i < b or i > c. When the function satisfies the first condition, the user can determine the transparency value by the value of the additional slider, and when it satisfies the second, the transparency value is considered equal to 1. Such a subset of transfer functions is sufficient to visualize the overwhelming array of medical data. The base of this method is the calculation of the volume integral along the rays passing through the pixels.
Max Intensity Projection (MIP)¶
The method suits for the primary analysis of the initial data, as it does not require setting of values of any parameters. The bas of this method is the computation of the maximum values of the intensities of the original data along the rays passing through the pixels.
Use this mode to view raw data sections in different projections and to measure the linear and angular dimensions of fragments of this data.
Try in One Click¶
You can try the Web3D DICOM Viewer demo online. But please be informed, that not all browsers and video cards are supported yet.
The product is under development. More features to come in future releases: automated segmentation, volume cut, automated ROI detection, and complex colored transfer functions, etc.
Web3D DICOM Viewer is under active development and locates in the private repository.
We are striving to publish it before end of 2017.
