CT Scan Viewer Online

Why Use an Online CT Scan Viewer?

After a CT scan (Computed Tomography), your imaging data is stored as DICOM files — typically dozens to hundreds of individual slices that together form a 3D volume of the scanned body region. These files are given to you on a hospital CD or made available through a patient portal, but viewing them requires DICOM software that most patients and non-radiologist physicians do not have installed.

Our online CT scan viewer renders these DICOM slices as standard images with appropriate windowing for CT data. CT images use Hounsfield Units (HU) to represent tissue density, and different window settings are needed to visualize bone (wide window), soft tissue (narrow window), or lung parenchyma (lung window). Our viewer automatically applies the windowing parameters stored in each DICOM file for optimal display.

Whether you want to review your CT results before a follow-up appointment, share specific slices with a specialist for a second opinion, or simply understand what your scan looks like, our viewer provides immediate access without the complexity of professional radiology software.
