A simulation study of ionizing radiation acoustic imaging (iRAI) as a real‐time dosimetric technique for ultra‐high dose rate radiotherapy (UHDR‐RT)

Purpose Electron‐based ultra‐high dose rate radiation therapy (UHDR‐RT), also known as Flash‐RT, has shown the ability to improve the therapeutic index in comparison to conventional radiotherapy (CONV‐RT) through increased sparing of normal tissue. However, the extremely high dose rates in UHDR‐RT have raised the need for accurate real‐time dosimetry tools. This work aims to demonstrate the potential of the emerging technology of Ionized...
