The goal of this clinical research study is to compare imaging software and 2 different radiation doses during a standard CT scan in order to "see" problems in the liver and still produce ...
Technical developments in radiation oncology are making it possible to deliver a prescribed radiation dose to radiation target volume with increasing accuracy. Therefore it is becoming ev...
This questionnaire is aimed at finding out if patients understand how much radiation they are being exposed to when they have a bone scan (99mTc-MDP)or an FDG PET/CT scan (18F-FDG PET/CT)....
The noncontrast-enhanced chest computed tomography (CT) is an emerging diagnostical tool in patient with chronic obstructive pulmonary disease (COPD). As shown in previous studies and poin...
In this study the treatment process will be closely monitored using a novel imaging technology, a PET/CT scanner. PET stands for Positron Emission Tomography and in this case it will be c...
X-rays are widely applied in the medical field for the diagnosis and treatment of diseases. Among the uses of X-rays in diagnosis, computed tomography (CT) has been established as one of the most info...
The present work describes that we try to construct a system that collects dose information that performed CT examination from multiple facilities and unified management. The results of analysis are c...
Gafchromic EBT3 films are applied in proton radiotherapy for 2D dose mapping because they demonstrate spatial resolution well below 1 mm. However, the film response must be corrected in order to reach...
The extensive literature review on human epidemiological studies suggests that low dose ionizing radiation (LDIR) (≤100 mSv) or low dose rate ionizing radiation (LDRIR) (
Computed tomography (CT) has recently been utilized in various medical settings, and technological advances have resulted in its widespread use. However, medical radiation exposure associated with CT ...
Administration of the total dose of radiation (RADIATION DOSAGE) in parts, at timed intervals.
The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.
The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv).
The relationship between the dose of administered radiation and the response of the organism or tissue to the radiation.
A treatment schedule in which the total dose of radiation is divided into large doses.
