Web1 de nov. de 2011 · Axial and coronal images acquired by using a 140-kVp tube voltage had significantly lower noise than scans acquired at 120 or 80 kVp with equivalent volume CT dose index. Diagnostic image quality was achieved when using a minimum tube current-time product of 120 mAs. Noise, CNR, and dose were jointly optimized with a pitch of 0.685. Web2 de ago. de 2024 · This increased distance allows for more chance that the scatter radiations path will result in it not reaching the receptor and therefore not reduce image …
Web6 de mar. de 2016 · The primary exposure technique factors the radiographer selects on the control panel are milliamperage (mA), time of exposure, and kilovoltage peak (kVp). Depending on the type of control panel, milliamperage and exposure time may be … Webradiograph must possess sufficient contrast to render the structural details visible. A choice of low kVp results in short-scale contrast having two steps – black and white. Choosing a high kVp creates films with a long-scale contrast of five steps – black, dark gray, medium gray, light gray, white. Optimum kVp for any body part
Web12 de abr. de 2024 · Peak tube voltage (kVp): LDCT has been performed using tube voltages of less than or equal to 100 kVp [ 51 ]. Therefore, 80–100 kVp is commonly used in LDCT. Reducing the voltage from 120 kVp to 80 kVp increases the image noise and would require a four-fold increase in the tube current to maintain the image quality [ 52, 53, 54 ].
