Radiotherapy dose calculation algorithms are essential components of modern treatment planning, ensuring that the prescribed radiation dose conforms as closely as possible to a patient’s tumour while ...

The number of CT examinations in pregnant patients has grown constantly during the past decades. But human embryos and foetuses are sensitive to ionizing radiation doses greater than 0.1 Gy. The ...

INFORMATION ON THE PATHWAYS through which radionuclides are transported to the public from a contaminated site provides the starting point for calculating the dose to individuals and for estimating ...

Computed tomography -- also known as computed axial tomography, a CT scan, or a CAT scan -- is a tool doctors use to diagnose many types of health problems. Special X-ray equipment creates images of ...

» Should we be adjusting our mammographic techniques to produce images with the lowest possible radiation dose to the patient? » What determines the radiation dose to the breast of my patients in ...

Dose conversion: A deep learning model predicts the Monte Carlo (MC) dose distribution from the pencil beam (PB) dose, for a prostate cancer case. (a) PB dose distribution; (b) converted dose ...

» How much radiation is safe for me? There are radiation dose limits for staff recommended by the International Commission on Radiological Protection (ICRP) that most countries tend to adopt.

Radiation is everywhere. Some naturally occurs in gases, such as radon, released from the ground. Some comes from the sun. And some is man-made in the form of X-rays, radio waves and nuclear power.

Pancreatic cancer is notoriously difficult to treat, partly because surgery is not possible or is ineffective. MSK has developed a high-dose form of radiation therapy that can give safe, effective ...
