What is it indicated for?
Torch™ software is intended to provide estimates (deterministic) of absorbed radiation dose at the voxel level following internal administration of approved radioactive products. This is dependent on input data regarding biodistribution being supplied to the application. Torch software only allows voxel-based dose calculations. For use with internally administered radioactive products. Torch should not be used to deviate from approved product dosing and administration instructions. Refer to the product's prescribing information for instructions.
Indications for use as stated in the FDA summary.
