High-dose-rate brachytherapy for eyelid carcinoma: Implant technique and review [PDF]

Journal of Contemporary Brachytherapy
Eyelid carcinoma is a tumor often detected at an early stage, which can be managed surgically. In non-surgical cases, brachytherapy is a valid alternative or as adjuvant therapy when risk factors exist.

A Comparative Analysis of Different Prescription Points in High Dose Rate Brachytherapy of Cervical Cancer [PDF]

Iranian Journal of Medical Physics, 2022
Introduction: The dose prescription point in high dose rate (HDR) intracavitory brachytherapy (ICBT) of cervical cancer is Manchester point A but the localization of this point has a wider variation.

Application of a scattering foil to increase beam transmission for cyclotron based proton therapy facilities

Frontiers in Physics, 2022
In proton therapy, high dose rates can reduce treatment delivery times, allowing for efficient mitigation of tumor motion, as well as increased treatment efficiency and patient throughput.

Absence of a dose-rate effect in the transformation of C3H 10T1/2 cells by α-particles [PDF]

, 1987
The findings of Hill et al. (1984) on the greatly enhanced transformation frequencies at very low dose rates of fission neutrons induced us to perform an analogous study with -particles at comparable dose rates. Transformation frequencies were determined

Focal salvage high-dose-rate brachytherapy with implantable rectum spacer for locally recurrent prostate cancer after initial low-dose-rate with grade 3 rectal toxicity

, 2023
Purpose: Locally recurrent prostate cancer after previous radiation therapy remains challenging. One of the cura-tive options for these patients is salvage brachytherapy.
