background long-term clinical symptoms and functional status of above-knee amputees are not well documented. this study documents the long-term outcomes of war related above-knee amputations. objective to study the long-term outcomes of unilateral above-knee amputation. materials and methods the study consisted of a comprehensive assessment, examination, and review of history and wartime medica...

introduction based on task group no. 43 (tg-43u1) recommendations, water phantom is proposed as a reference phantom for the dosimetry of brachytherapy sources. the experimental determination of tg-43 parameters is usually performed in water-equivalent solid phantoms. the purpose of this study was to determine the conversion factors for equalizing solid phantoms to water. materials and methods t...

background: in myocardial perfusion spect imaging, images are degraded by photon attenuation, the distance-dependent collimator, detector response and photons scatter. filters greatly affect quality of nuclear medicine images materials and methods: a phantom simulating heart left ventricle was built. about 1mci of 99mtc was injected into the phantom. images were taken from this phantom. some fi...

The technique of high resolution CT (HRCT) requires thin (1–1.5 mm) sections and a special reconstruction algorithm to maximize detail in the lung parenchyma [ 1 ] (Fig. 2.1 ). HRCT images may be reconstructed from a volumetric dataset or may be acquired using noncontiguous images at 1–2 cm intervals. If volumetric acquisition is performed, coronal and sagittal reconstructions may be obtained, ...

introduction quality control is an important phenomenon in nuclear medicine imaging. a jaszczak spect phantom provides consistent performance information for any spect or pet system. this article describes the simulation of a jaszczak phantom and creating an executable phantom file for comparing assessment of spect cameras using simind monte carlo simulation program which is well-established fo...
