Flash Radiotherapy: Skin Pigmentation As A Non-Invasive Indicator For Radiation-Induced Damage, Brady Mccallister Jun 2021

Flash Radiotherapy: Skin Pigmentation As A Non-Invasive Indicator For Radiation-Induced Damage, Brady Mccallister

ENGS 88 Honors Thesis (AB Students)

FLASH ultra-high dose rate radiotherapy (RT) is one of the most rapidly growing subfields of radiation oncology today due to its potential to increase the limits of the therapeutic ratio. The FLASH effect, which includes heightened normal tissue sparing paired with iso-effective tumor cell killing, has been literature documented, in a limited manner, in rodent models, a few large animals, and one clinical patients.

A porcine-based experiment was conducted to test the effects of FLASH RT on normal tissue compared to conventional (CONV) RT. A clinical linear accelerator (LINAC) was reversibly converted to be capable of FLASH RT. A female …
