To learn Basic physics of scanning with multidetector CT and the design of 128-channel (256-Slice) CT. Basics of radiation dose measurement in multichannel CT scanning and which imaging parameters to utilize for low radiation dose to the patients.

Basic Physics of  CT imaging. Basic design of 128-channel (256-slice) CT scanner: Gantry design including X-ray tube and detector configuration and table design. Scanning and Image Acquisition with 128-channel, 256-slice CT scanner. Basics of radiation dose measurement in multichannel CT scanning. Choosing the imaging parameters which affect radiation dose.

Understanding the design of new multislice CT scanners is essential to obtain improvement in image quality. With the increasing use of CT there is concern for increased radiation risk to the patients. The exhibit describes how the design of new 256-slice CT and the selection of  imaging parameters can be utilized to obtain maximum reduction in radiation dose to the patients.
