Biology guided radiotherapy combines radiation therapy with PET imaging, which is a biological image modality. This technology uses the signal from the tumor and can shoot directly on the tumor's location. Hopefully, this technology will open the door to treating more advanced cancer.
There is good news for any facility interested in this technology; it fits into a standard linear accelerator vault. The shielding used on the standard vaults is sufficient to handle the six megavoltage primary beams' output. The only special consideration for facilities is the need for shielding for the PET CT scanner. Most facilities would need to add this shielding.
Patients won't notice any changes in the treatment they receive. The patient will receive the PET tracers and go into the Relfexion vault instead of the PET CT vault.
The CT guided portion of the technology was pending FDA clearance as of November 2019. Once this technology receives approval, it will administer convention radiotherapy with CT guidance using a 16 slide CT scanner. After this data is collected, the submission process will begin for FDA for clearance for Biology guided radiotherapy.
