Interactive SPECT
Projections, sinograms & reconstruction
Rotate the gamma camera, acquire projections, and reconstruct the activity distribution. Everything runs locally in your browser; optional DICOM files never leave your device.
How to explore
Follow the image from measurement to recovery.
- 01
Acquire
Drag the detector or run an automatic 360° scan to collect projections.
- 02
Read the sinogram
Watch each projection become a row and each hot spot trace a sinusoid.
- 03
Reconstruct
Compare simple and filtered backprojection as the image builds angle by angle.
