When radiation treatment is delivered by a medical accelerator, the amount of exposure that is actually absorbed by the patient has been estimated based on dosage administered and other parameters. The Delta4 Discover, a product from ScandiDos, a Swedish firm, has received FDA clearance to be used to accurately measure the amount of radiation that moves past the patient and calculate the amount that’s actually absorbed.
The system allows for immediate verification of dosage delivered in a fairly non-intrusive way, letting techs go about the procedures pretty much as they normally would while knowing that the required therapy is being absorbed.
The detector simply sits on the receiving end of the radiation beam, past the patient, and counts the number of particles that strike it.
Here’s a promo video for the Delta4 Discover:
