in order to improve the performance of a newly developed radiochromic film, gic-79, somedosimetric characteristics of this film have been studied based on relevant standard practice. the presentstudy describes some parameters that may affect the dosimeter response before, during, and after irradiation. the effect of absorbed dose rate on dosimeter response was determined by irradiating dosimete...
A device for measuring the power of laser radiation.has been designed. The consists transmitter and receiving part. includes optical radiation source system collimation radiation. receiver part silicon photodiodes, electronic signal processing unit measurements.
Slowed processing speed is common in elderly subjects and frequently related to cerebral small vessel disease. Previous studies have demonstrated associations between processing speed and subcortical ischemic lesions as well as cortical alterations but the precise functional-anatomical relationships remain poorly understood. Here we assessed the impact of both cortical and subcortical changes o...
introduction: intensity modulated radiation therapy (imrt) is one of the cancer treatment methods. it is important to selectively aim at the target in this way, which can be performed using a multileaf collimator (mlc). materials and methods: in order to specifically irradiate the target volume in radiotherapy to reduce the patient absorbed dose, the use of multileaf collimator has been investi...
