We analyzed the data for 53 patients with histologically proven primary squamous cell carcinoma of the head and neck treated with radiotherapy between February 2006 and August 2009. All patients underwent contrast-enhanced (CE)-CT and (18)F-fluorodeo

2-[(18)F]fluoro-2-deoxy-D: -glucose (FDG) is known to accumulate in benign conditions such as infection and inflammation as well as in malignancy. Vaccination may cause transient inflammation of lymph nodes, which may induce false-positive findings o

Iterative reconstruction methods can reduce the noise of computed tomography (CT) images, which are expected to contribute to the reduction of patient dose CT examinations. The purpose of this study was to investigate impact of an iterative reconstru

A Study of Collimator Scatter Factors of Rectangular Irradiation Fields Using the Virtual Source Plane

Autor: Hidekazu Nambu, Eiji Shiba, Naoki Kinoshita, Fumiaki Uto

Publikováno v: Japanese Journal of Radiological Technology. 66:225-230

Kim introduced the geometric weighting factor concept into the field mapping method, and estimated collimator scatter factors of rectangular fields by correcting collimator exchange effects. The source plane is present at a specific position in the f
