Instructions
Load
1-hour
(left) and
3-hour
(right) planar thoracic bone scintigraphy DICOM files (uncompressed).
Draw a
heart ROI
on the 1-hour panel: click and drag to set centre and radius.
Click on the 1-hour panel (without dragging) to place a
contralateral lung ROI
with the same radius as the heart ROI.
The 3-hour ROIs are automatically copied with the same radius (use “Copy ROI 1h → 3h” to copy positions).
Move ROIs by hovering over them and dragging (cursor changes).
Delete individual ROIs with the ✕ button.
All measurements are numeric only; no diagnostic interpretation is applied.
