Dicom Open Viewer

Developed in Delphi, Dicom Open Viewer is a lightweight and portable application you can use to open and view DICOM media files. It's partially based on ezDICOM sources and features geometry, zoom and window level (WL) options, in addition to a series preview mode, DICOM directory tree, and DICOM tags.

Since there's no setup involved, you can save the downloaded files to a custom directory on the disk or copy them to a USB flash drive in order to seamlessly launch the tool on any machine without previous installers. It doesn't change Windows registry settings and doesn't need any DLLs to run.

As far as the GUI goes, Dicom Open Viewer has a large window that displays navigation, cinematic and mouse options, enabling you to open not only DICOM-formatted files, but also DICOMDIR, BMP and JPG imaged.

It's possible to rotate or flip the images, zoom in and out, opt for a preset WL setting (e.g. CT Chest Bone, CT Abdomen Muscle, MR Head Brain), or customize WL when it comes to the sensibility, center and width.

Moreover, you can view patient information, adapt the image to the container or view its original dimension, start an image sequence, as well as restore settings to default anytime. Modified files can be saved. Help documentation is available for less experienced users.

We haven't come across any stability issues in our tests, thanks to the fact that it didn't freeze, crash or prompt error message. Unsurprisingly, it left a small footprint on the computer's performance, running on a low amount of CPU and RAM.

To sum it up, Dicom Open Viewer delivers a simple solution to opening and viewing DICOM medical images.
