[Examination of patient skin dose during abdominal interventional radiology using a GAF system].

Radiation-induced skin injury caused by interventional radiology(IVR)is a deterministic effect. If exposure dose exceeds threshold dose, injuries may occur. It therefore is important to understand the maximum exposure dose in skin.

[Accuracy of measurement of radiochromic film density for high-energy X-rays].

Radiochromic film (RC-film) is of great interest as a film-type dosimeter for radiation oncology applications. We present a two-dimensional image-based evaluation of the measurement accuracy of a commercial RC-film product (Gafchromic MD-55-2 film, ISP TECHNOLOGIES, Inc.) by using a commercial Laser Densitometer (Model 1710, Computerized Medical Systems, Inc.
