Effect of conventional and ultra-high dose rate "FLASH" irradiations on preclinical tumour models: A systematic analysis: Tumour response to CONV and UHDR irradiation.

International Journal of Radiation Oncology, Biology, Physics, 2023
PURPOSE When compared to conventional dose rate irradiation (CONV), ultra-high dose rate irradiation (UHDR) has shown superior normal tissue sparing. However, a clinically relevant widening of the therapeutic window by UHDR, termed "FLASH effect", also ...

Characterization of a Diode Dosimeter for UHDR FLASH Radiotherapy

Medical Physics, 2023
BACKGROUND: Ultra-high dose rate (UHDR) FLASH beams typically deliver dose at rates of \u3e40 Gy/sec. Characterization of these beams with respect to dose, mean dose rate, and dose per pulse requires dosimeters which exhibit high temporal resolution and

A Simulation Study of Ionizing Radiation Acoustic Imaging (iRAI) as a Real-Time Dosimetric Technique for Ultra-High Dose Rate Radiotherapy (UHDR-RT)

Medical Physics, 2021
PurposeElectron‐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 ...

Printing Image Re-conversion Method for Adopting to Standard Dynamic Range (SDR) Images Converted from Twilight Ultra-high-dynamic-range (UHDR) Images

Electronic imaging
Printing display images normally proceeds well provided they comply with the SDR gamut supported by color management systems (CMS), like ICM used in Windows OS. Twilight vision, unfortunately, complicates this process, as it is quite difficult to convert
