Dicompyler imports many DICOM modalities display them with 2D image viewer , It has a plugin system that allow developers to extend its functionalities by building their own plugins. SMILI's UI is built with Qt library, but it provides a command-line interface as well for experienced users, which can take advantage of extending its default functionalities with python scripting.
Read more about InVesalius in here. Horos is providing training and comprehensive documentation for its users as it has growing community of users and doctors including developers and researchers. However, I would recommend 3Dim Viewer for its better 3D capabilities.

Typically, the photographer enters his name, contact information, captions, keywords, and copyright information to tag his images. Similarly, for radiology images, these fields are used to enter information such as clinical history, diagnosis, comments, and copyright information [ Figure 9 ].
Once all the images are tagged, a search for specific images can be performed within an entire collection using the IPTC keywords.
A list of such software packages can be found at the IPTC website. For example, displaying a series of axial images of the abdomen would be more effective in depicting the imaging findings in a case of abdominal tuberculosis than showing a few representative images. Fortunately, there are several options for performing this with minimal effort.
Software packages such as PACstacker, StackView, and RadViewer have been developed to enable import of a series of images and to display them interactively as a stack. Images need to be converted to other formats before they can be imported into the presentation.
The resultant images will have a fixed contrast, set at the time of file conversion. Incorporation of this plug-in gives the presenter the ability to directly import and display DICOM images. Further, it gives the presenter the freedom to scroll through image stacks, dynamically manipulate the window level and window width, and even to zoom and crop the images during the presentation.
There are certain situations where a large number of images have to be displayed in a presentation. Creating a presentation with a large set of digital images would take a while, as a separate slide has to be created for each photo. Fortunately, for rapid creation of slideshows, platform-independent software programs are available free of cost.
Irfanview and Xnview are software programs that permit rapid creation of slideshows. The slideshow can then be saved as an executable file that will run on any computer irrespective of the operating system and the presence or absence of image management software by simply double clicking the. The disadvantage with this mode of presentation is that it displays only one image per slide and it is not possible to mix images with text or other graphics.
This article introduces the reader to a few basic concepts regarding digital image management. There are several other such software programs and techniques that can be similarly used by radiologists to optimize their practice. It is essential to try out a number of such programs before finding the one that best suits each purpose.

Introduction As radiologists we deal with DICOM digital imaging and communications in medicine image files sourced from different modalities, either in a standalone or integrated manner. Open in a separate window. Figure 1. Figure 2. How can one Read the Header Information?
Figure 3. Because JPEG files are small in size and extremely portable, they are the preferred format when transferring images over the Web. The advantage of the JPEG format is that it facilitates use of compression to reduce file size. Typically, the least noticeable bits of information are removed by complex mathematical algorithms, so that the image is represented with less information.
When saving as a JPEG file, options are available for selecting the amount of compression that can be applied. The more the file is compressed lossy compression , the more the original image information lost; such an image will not look good when reproduced.
Lesser degrees of compression lossless compression retain high image quality, but this is achieved at the cost of a large file size. Since TIFF images are saved without compression or with a lossless compression scheme they retain the original image quality and often are large in size. A major advantage of this format is its ability to save animations. It can store only a limited amount of color information and is becoming increasingly unpopular as a format for storing digital images. It has better browser compatibility and supports greater color depth than the GIF format.
Its lossless compression enables better image quality, though at the expense of large file sizes. Table 1 Comparison and applications of different image file formats.
Table 2 Sizes of images produced by digital imaging modalities. Figure 4. Figure 5. Figure 6. Figure 7 A-F. Lossless compression techniques ensure that the original image is exactly reconstructed from the compressed data.
These techniques take advantage of redundancy in data and eliminate it. They generally permit reduction of file sizes by a factor of 2 or 3. Lossy algorithms allow reconstruction of an approximation of the original data. Depending on the degree of compression, visually appreciable distortions may find their way into the image. These schemes often reduce the file sizes by a factor of 10 or more. How can I Organize my Image Collection? Figure 8. Laws concerning the use of this software vary from country to country.
We do not encourage or condone the use of this program if it is in violation of these laws. In Softonic we scan all the files hosted on our platform to assess and avoid any potential harm for your device.
Our team performs checks each time a new file is uploaded and periodically reviews files to confirm or update their status. This comprehensive process allows us to set a status for any downloadable file as follows:.
We have scanned the file and URLs associated with this software program in more than 50 of the world's leading antivirus services; no possible threat has been detected. Based on our scan system, we have determined that these flags are possibly false positives. It means a benign program is wrongfully flagged as malicious due to an overly broad detection signature or algorithm used in an antivirus program.
