John Joly (/ ˈ dʒ oʊ l i /; 1 November 1857 – 8 December 1933) was an Irish geologist and physicist known for his development of radiotherapy in the treatment of cancer. He is also known for developing techniques to more accurately estimate the age of a geological period, based on radioactive elements present in minerals, the uranium–thorium dating.

"Radiation therapy" defined as the utilization of electromagnetic or particle radiation in medical therapy has 3 main branches, including external beam radiation therapy (teletherapy), locoregional ablative therapy (such as brachytherapy (sealed source radiation therapy), selective internal radiotherapy (SIRT), radiofrequency ablation ...
Like a conventional machine used for X-ray external beam radiotherapy (often referred to as a linear accelerator or linac, their main component), it [the tomotherapy machine] generates the radiation beam, but the external appearance of the machine, patient positioning, and treatment delivery differ. Conventional linacs do not work on a slice-by ...

FLASH radiotherapy is an emerging form of radiotherapy which delivers a high dose of radiation to the patient in an ultra-short time frame which produces a tumour killing effect comparable to conventional radiotherapy but with less damage to surrounding healthy tissue.
