Estimation and calculation of radiation dose of copper-64 for nuclear medicine usage
Radioactive materials used in nuclear medicine are the radioisotopes or drugs that are identified with radioisotopes. A radiopharmaceutical transfusion is one of diagnostic methods and a radiation value approved should be measured. The nuclear medicine images of diagnostic methods can be made by a gamma camera (γ-camera). In this article, we used MCNPX2.4 for internal dosimetry assessment when ...
متن کاملImage processing by alternate dual Gabor frames
We present an application of the dual Gabor frames to image processing. Our algorithm is based on finding some dual Gabor frame generators which reconstructs accurately the elements of the underlying Hilbert space. The advantages of these duals constructed by a polynomial of Gabor frame generators are compared with their canonical dual.
متن کاملSingle-Sensor Camera Image Processing
In recent years a massive research and development effort has been witnessed in color imaging technologies in both the industry and the ordinary life. Color is commonly used in television, computer displays, cinema motion pictures, print, and photographs. In all these application areas the perception of color is paramount for the correct understanding and dissemination of the visual information...
متن کاملDetermination of Optimum Planar Imaging Parameters for Small Structures with Diameters Less Than the Resolution of the Gamma Camera
Introduction: The limited spatial resolution of the gamma camera hinders the absolute quantification of planar images of small structures. The imaged structures are affected by partial volume effects (PVEs), which can spread activity and lead to underestimation of the regional distribution. The use of optimum planar parameters reduces the impact of the limited spatial resolution of the gamma c...
متن کاملFeasibility of portable gamma camera imaging in intraoperative radioguided parathyroid adenoma identification
Novel surgical applications include radioguided procedures in parathyroidectomy operations. In order to investigate the feasibility of usage of the portable gamma camera in parathyroidectomy operations; intraoperative radioguided parathyroidectomy operation was performed in three hyperparathyroidism patients with inconclusive preoperative parathyroid scintigraphy results. Intraoperative portabl...
