Frontend Developer at Wix, Denis Dovgan, created his own web application, Voxel Viewer, which allows you to view computed tomography (CT) results directly in a browser or on a smartphone, bypassing the need for specific software for Windows.
The IT expert spoke about the creation of the tool in a series of posts on the social network X (Twitter). According to Denis, the idea arose due to the inconvenience of working with files that dental clinics usually send to patients after an examination.
«Every time after the dentist, I would receive CT scan files in my email, which normally only open in some very specific Windows software. And I wanted a simple scenario: I got a picture — opened the website — selected a folder — and immediately viewed it in a browser, phone, or tablet,» the developer explains.
To implement the idea, Denys used the method of reverse engineering files using the Codex AI tool. This allowed him to analyze the structure of the formats and understand how the CT data is stored inside. Voxel Viewer works as a local web/PWA viewer: it analyzes the folder with images directly in the browser, collects the volume in a background thread (worker) and visualizes the 3D model using the Three.js library.

Currently, the tool supports formats such as Sirona GALILEOS, OneVolume and DICOM. In addition to the volumetric model, the user can view axial, sagittal and coronal slices with the ability to zoom. The developer wrote the main part of the functionality over the weekend, and spent a few more evenings configuring navigation, PWA mode and infrastructure.
The Voxel Viewer logo design was also created using AI. Aitivets generated it using Gemini to accurately convey the idea of an isometric cube with three cross-section planes.
Denis Dovgan noted that the project’s open source code is available on GitHub. He also offered cooperation to clinics that want to provide patients with a convenient way to view images on their personal devices without having to install outdated software.
«If you are a clinic and want to give people a normal way to receive and view their images on personal devices without dancing with Windows software, write to me,» the developer noted.
