Weasis

Designed mainly for medical professionals, but also very much usable by any day-to-day user with an inclination towards medical file and image study, Weasis is a cross-platform, Java-based utility that provides a staggering array of tools for viewing DICOM (short for Digital Imaging and Communications in Medicine) files and radiological images.

Before we dive deeper into what really makes this app useful, there are a few things worth mentioning. First off, the fact that this is a portable app, which means that not only it doesn't require installation, but it can also be launched in mere seconds, directly from a flash drive, on any Windows PC or Mac that's running Java.

One of the best things about this app is the fact that it comes with support for a wide array of DICOM files, including multi-frame, enhanced, MPEG-2, MPEG-4, MIMI Encapsulation, SR, PR, KOS, and AU, coming from all storage mediums, including CDs and DVDs or other portable media. It's also quite capable of working with most other photo formats as well, with support for TIFF, BMP, FlashPix, GIF, JPEG, PNG, and PNM.

One other area where this app shines is in the image manipulation department, as it allows you to effortlessly manage photos with specialized and intuitive tools for panning, zooming, windowing, rotating, flipping, scrolling, and filtering pictures.

Since we're on the subject, a special notice goes out to the "multi-viewer" feature which makes it possible for you to view multiple images in various customizable layouts, quite handy for situations when you want to compare various images on one screen.

Last but not least, the app's measurement and annotation tools which, as we're sure you'll see, are many. Ranging from simple tools that can help you calculate the distance between two selected points, to more complex ones that allow you to calculate any custom-defined share, area, or angles, the app has got you covered.

Last but not least, you might also be interested in knowing that the app allows you to save the measurements and annotations in DICOM PR or directly to XML format. There are a few other similar options as well, as you can export DICOM to ZIP, ISO, TIFF, JPEG, and PNG formats if you want.

All things considered, Weasis is a very compelling and feature-packed utility that is sure to come in handy to medical professionals and, why not, even patients. It packs a praiseworthy number of useful features and, thanks to its modular structure, it can be further improved with the help of plugins.

The only drawback is the interface which could have been better, as we're sure users running Windows 10 on their tables will surely struggle a bit with the tiny buttons and desktop-orientated controls.
