This study aimed to survey technical variations in total body irradiation (TBI) across Japan. A web-based questionnaire investigating technical aspects (irradiation method, in vivo dosimetry, organ shielding, and boluses) of TBI was distrib...
Initial demonstration of the Scratch-PET concept: an intraoperative PET with a hand-held detector [0.03%]
Scratch-PET概念的初步演示：手持探测器的术中PET
Taiyo Ishikawa,Yuma Iwao,Go Akamatsu et al.
Taiyo Ishikawa et al.
Positron emission tomography (PET) is a valuable tool for diagnosing malignant tumors. Intraoperative PET imaging is expected to allow the more accurate localization of tumors that need resections. However, conventional devices feature a la...
Cone-beam computed tomography (CBCT) image-quality improvement using a denoising diffusion probabilistic model conditioned by pseudo-CBCT of pelvic regions [0.03%]
使用基于伪骨盆区域的去噪扩散概率模型改善锥形束计算机断层扫描(CBCT)图像质量
Masayuki Hattori,Hongbo Chai,Toshitada Hiraka et al.
Masayuki Hattori et al.
Cone-beam computed tomography (CBCT) is widely used in radiotherapy to image patient configuration before treatment but its image quality is lower than planning CT due to scattering, motion, and reconstruction methods. This reduces the accu...

Mahdi Mansoori Kia,Soheila Refahi,Parinaz Mehnati et al.
Mahdi Mansoori Kia et al.
Lead-based radiation shielding used usually in radiology departments is being replaced by non-lead shields due to concerns over toxicity, high weight, and the impossibility of applying it in the imaging field. New studies refer to the use o...
Retaking assessment system based on the inspiratory state of chest X-ray image [0.03%]
基于胸片吸气状态的重考评估系统
Naoki Matsubara,Atsushi Teramoto,Manabu Takei et al.
Naoki Matsubara et al.
When taking chest X-rays, the patient is encouraged to take maximum inspiration and the radiological technologist takes the images at the appropriate time. If the image is not taken at maximum inspiration, retaking of the image is required....
Radiation dose at the eye lens of patients undergoing radiation therapy for head and neck cancer [0.03%]
