Radiation dose issues in multi-slice CT scanning ImPACT
Multi-slice or multi-detector row CT scanners, capable of imaging four simultaneous, parallel slices in a single rotation, were first introduced in 1998. Since then, scanners with 6, 8, 10 and 16 slice capabilities have become available and have made a marked impact on the role of CT in the diagnostic radiology department. Most recently 32, 40 and 64 slice scanners have been announced and the t...
متن کاملCalculation of the Scattered Radiation Profile in 64 Slice CT Scanners Using Experimental Measurement
Introduction: One of the most important parameters in x-ray CT imaging is the noise induced by detected scattered radiation. The detected scattered radiation is completely dependent on the scanner geometry as well as size, shape and material of the scanned object. The magnitude and spatial distribution of the scattered radiation in x-ray CT should be quantified for development of robust scatter...
متن کامل64-slice CT scan in Kathmandu Medical College Teaching Hospital.
64-slice CT scan is a versatile newly introduced imaging technology, which is capable of diagnosing various diseases from head to toe. The 64-slice CT coronary angiography has a negative predictive value of 100%. Virtual images of bronchi, stomach and colon can provide definite diagnosis. Coronary artery calcification score which predicts coronary artery disease can be calculated by 64-slice CT...
متن کاملOptimization of Parameters in 16-slice CT-scan Protocols for Reduction of the Absorbed Dose
Introduction In computed tomography (CT) technology, an optimal radiation dose can be achieved via changing radiation parameters such as mA, pitch factor, rotation time and tube voltage (kVp) for diagnostic images. Materials and Methods In this study, the brain, abdomen, and thorax scaning was performed using Toshiba 16-slice scannerand standard AAPM and CTDI phantoms. AAPM phantom was used for...
متن کاملMulti-slice helical CT: scan and reconstruction.
The multi-slice CT scanner refers to a special CT system equipped with a multiple-row detector array to simultaneously collect data at different slice locations. The multi-slice CT scanner has the capability of rapidly scanning large longitudinal (z) volume with high z-axis resolution. It also presents new challenges and new characteristics. In this paper, we study the scan and reconstruction p...
