CT Scan Viewer Online
View your CT scan images directly in your web browser. Upload the DICOM files from your CT scan — whether from a hospital CD, patient portal, or imaging center — and see the computed tomography images rendered with proper bone or soft tissue window settings. No radiology software installation required.

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.

Frequently Asked Questions
What is a CT scan?
CT (Computed Tomography) is a medical imaging technique that combines multiple X-ray measurements from different angles to create cross-sectional images (slices) of the body. CT scans are commonly used to examine the chest, abdomen, pelvis, head, and spine, providing detailed views of bones, organs, and blood vessels.
How many files does a typical CT scan have?
A typical CT scan produces 100-500 DICOM files, with each file representing one cross-sectional slice. Thin-slice CT scans (1mm slices) of the entire abdomen can produce over 1,000 files. Each slice can be uploaded and viewed individually or in batches.
Can I see both bone and soft tissue from the same CT?
Yes. The same CT data can be displayed with different window settings to emphasize different tissues. Our viewer applies the default windowing stored in the DICOM file. For CT scans, this is typically optimized for the clinical indication — bone window for skeletal studies, soft tissue window for abdominal scans, or lung window for chest CTs.
Will this work with contrast-enhanced CT scans?
Yes. Contrast-enhanced CT scans (with IV contrast, oral contrast, or both) produce standard DICOM files that are fully supported. The contrast enhancement is part of the image data itself and will be visible in the rendered output.
