Differences in effective dose estimation from dose-area product and entrance surface dose measurements in intravenous urography.

open access: yesThe British Journal of Radiology, 2001
In this study, measurements of dose-area product (DAP) and entrance surface dose (ESD) were carried out in a sample of 25 adult patients who underwent intravenous urography (IVU). These measured quantities were used to estimate the effective dose E from the IVU examination, a quantity closely correlated to radiation risk.

Dose area product applied to stereotactic radiotherapy

open access: yes, 2022
Evolution of radiotherapy techniques, in particular with the advent of stereotactic treatments, led to an increased use of small radiation beams allowing a better dose conformation to the volume while sparing the surrounding normal tissues. As a consequence, clinical conditions are significantly different from the reference conditions in terms of ...
