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...
The extensive literature review on human epidemiological studies suggests that low dose ionizing radiation (LDIR) (≤100 mSv) or low dose rate ionizing radiation (LDRIR) (
Videofluoroscopic swallowing studies expose both the patients and the staff to ionising radiation. Although the radiation exposure is considered low compared to other diagnostic procedures, it is stil...
To analyze possible influencing factors on radiation exposure in pediatric chest CT using different approaches for radiation dose optimization and to determine major indicators for dose development...
Interventional radiology is a rapidly evolving speciality with potential to deliver high patient radiation doses, as a result high standards of radiation safety practice are imperative. IR radiation s...
A comparative study of radiation dose measured in anthropomorphic phantoms.
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.
