Evaluation of the electrical properties of a lead (II) iodide based-dosimeter based on mechanical flexibility for surface dose measurements in radiotherapy

M.J. Han、S.W. Yang、Jaeyong Jung 等 8 位作者2020-08-17Journal of Instrumentation

In radiotherapy, point doses via surface dose measurement are confirmed using a dosimeter attached to the patient's skin. This results in an error margin of about 11.8% or higher because the attachment site is visually confirmed. Thus, a digital flexible array dosimeter that can analyse body surface area is needed. He…
