Radiological imaging protection: a study on imaging dose used while planning computed tomography for external radiotherapy in Japan
Kito S, Suda Y, Tanabe S, Takizawa T, Nagahata T, Tohyama N, et al.
J Radiat Res . 2023 Dec; 65(2):159-167. PMID: 38151953
Previous studies have primarily focused on quality of imaging in radiotherapy planning computed tomography (RTCT), with few investigations on imaging doses. To our knowledge, this is the first study aimed...

Evaluating the output stability of LINAC with a reference detector using 3D water phantom
Shimozato T, Kojima T, Sakamoto M, Hata Y, Sasaki K, Araki N
Igaku Butsuri . 2014 Feb; 32(4):176-81. PMID: 24568022
We report the discovery of abnormal fluctuations in the output obtained when measuring a water phantom and adjustments that reduce these outliers. Using a newly developed three-dimensional scanning water phantom...
