The present embodiments relate generally to enabling an end user - e.g. medical physicists - to monitor radiation therapy and, with integration to the LINAC, adaptive radiotherapy. Embodiments record signals already released during radiotherapy, requiring no new irradiation of the patient for in vivo, in line, dose monitoring. Furthermore, as the transducers will be coupled to the patient with ultrasound gel, the present embodiments are not invasive to patients and will not introduce new discomfort during therapeutic procedures. The addition of the RiAD system provides the end user with additional information during the treatment of the patient, allowing for real-time beam tracking and dosimetry, enabling the end user to practice adaptive radiotherapy. The RiAD system enables the end user to ensure that proper dose delivery is occurring with each new beamlet and dose deposition, empowering them to adapt the medical treatment as it is performed and increase its precision in conventional electron beam radiotherapy, electron FLASH radiotherapy, and intraoperative electron beam radiotherapy.
