Possible application of an imaging plate to space radiation dosimetry.
Fading correction plays an important role in the application of commercially available BaBrF:Eu2+ phosphors: imaging plates (IP) to dosimetry. We successfully determined a fading correction equation, which is a function of elapsed time and absolute temperature, as the sum of several exponentially decaying components having different half-lives. In this work, a new method was developed to elimin...
متن کاملImproved Imaging Plate Dosimetry for X-rays in Interventional Radiology
A new method using imaging plates (IPs) to evaluate patient doses in interventional radiology (IR) procedures is developed. IPs are made of photostimulated luminescence (PSL) materials, are highly sensitive two-dimensional radiation sensors, and can be reused repeatedly. Mapping skin doses in complex fluoroscopy interventions helps determine the probability of a possible injury, helps find area...
متن کاملDevelopment of dosimetry using detectors of diagnostic digital radiography systems.
Dosimetry using an imaging plate (IP) of computed radiography (CR) systems was developed for quality control of output of the x-ray equipment. Sensitivity index, or the S number, of the CR systems was used for estimating exposure dose under the routine condition: exposure dose from 1.0 to 1.0 x 10(2) microC kg(-1), tube voltages from 50 to 120 kV, and added filtration from 0 to 4.0 mm Al. The I...
متن کاملI-124 Imaging and Dosimetry
Although radioactive iodine imaging and therapy are one of the earliest applications of theranostics, there still remain a number of unresolved clinical questions as to the optimization of diagnostic techniques and dosimetry protocols. I-124 as a positron emission tomography (PET) radiotracer has the potential to improve the current clinical practice in the diagnosis and treatment of differenti...
متن کاملNoninvasive Dosimetry and Monitoring of TTT Using Spectral Imaging
Transpupillary thermo therapy (TTT) is a slow (60 seconds) photothermal treatment of the fundus with a near-infrared (780-810nm) laser irradiating a large spot (0.51. mm) on the retina. Due to high variability in ocular tissue properties and the lack of immediately observable outcome of the therapy, a real-time dosimetry is highly desirable. We found that fundus spectroscopy and spectrally-reso...
