British Journal of Cancer, 2005 Conventional radiation therapy directs photons (X-rays) and electrons at tumours with the intent of eradicating the neoplastic tissue while preserving adjacent normal tissue. Radiation-induced damage to healthy tissue and second malignancies are always a concern, however, when administering radiation.

Srpski arhiv za celokupno lekarstvo, 2021 Proton beam therapy (PBT) is an advanced type of radiotherapy that shows a dosimetric advantage over photon beam therapy and provides superior dose distribution. PBT may improve patient survival by improving the local disease control while reducing toxicity to normal organs, which may result in fewer treatment-related complications.

Sensors, 2022 Several detectors have been developed to measure radiation doses during radiotherapy. However, most detectors are not flexible. Consequently, the airgaps between the patient surface and detector could reduce the measurement accuracy.

Proton-counting radiography for proton therapy: a proof of principle using CMOS APS technology [PDF]
, 2014 Despite the early recognition of the potential of proton imaging to assist proton therapy (Cormack 1963 J. Appl. Phys. 34 2722), the modality is still removed from clinical practice, with various approaches in development. For proton-counting radiography
