Y90 Dosing

Y90 Dosing applies published yttrium-90 microsphere dosimetry formulations to values you enter, and shows the working. Glass (TheraSphere) and resin (SIR-Spheres), each computed with its own manufacturer's published constants. Built by an interventional radiology fellow for use alongside treatment planning, not in place of it. WHAT IT DOES Calculate activity across one or many perfused territories, each configured independently as single compartment or partition. Enter volumes, T/N ratio, lung shunt fraction, and target dose; see the resulting activity with every step exposed. Order vials against a real calendar. For glass, the vial grid decays each candidate from its calibration date to your treatment date and time, so you can see what a 3 GBq vial actually delivers on a Wednesday afternoon rather than working it out by hand. Or set the date and time you need and see the vial activity to order for it. For resin, choose the ordering day and see the volume to draw, the vials needed, and the sphere count. Save cases and export a one-page PDF summarizing the plan, the vial order, and every input that produced it. SCOPE Y-90 microspheres: glass (TheraSphere) and resin (SIR-Spheres). Manual numeric entry only. No BSA dosing, no voxel or DICOM dosimetry, no overlapping territories.
