Online DICOM Viewer - open a zip of your MRI / CT / ultrasound scan CD in Chrome

🌐 ไทย →

Just open a zip of your MRI, CT or ultrasound scan CD in Chrome on your phone or tablet - or computer. Nothing to install, no account, and your medical images are never uploaded (verify it yourself). Open the viewer → · How to use →

Background

Kasidit Yusuf, ClearEvo co-founder (about), wanted to look at his own CT scan CD on his phone, in Chrome, without finding a PC - so he wrote this viewer, then made it free for everyone as a gift from ClearEvo. No ads, no sign-up, no upsell; source code under the GPL.

The demo scans are his own head CT and MRI, anonymized, so you can try the viewer with real data.

Features

Series browser, slice scrolling, window/level presets (soft tissue, brain, lung, bone), measure and angle, ultrasound cine clips, DICOM tags, JPEG 2000 / RLE / JPEG Lossless CDs, Simple and Advanced (PACS) modes, English and ไทย. Reads gigabyte CDs slice by slice, so even a 1.2 GB CD opens in seconds.

Before you use it

Not a medical device. It is for viewing your own scans, not for diagnosis - that belongs to your radiologist and their certified tools. Provided as is, without warranty; best-effort support through GitHub issues or the comments on the how-to guide.

Other tools and discontinued projects →

Kasidit’s earlier browser tools (QR codes, audio converter, hex editor, GIS converter, GNSS monitor, serial terminal and more) are still online but unrelated to medical imaging - they share a page with ClearEvo’s older, discontinued projects.

Full disclosure: this post - and any code or tool it describes - was co-authored with Claude (Anthropic’s AI, via Claude Code). I directed, guided and reviewed. I don’t want to pretend otherwise.
