1) Understand the importance of the digital localizer to the tube current modulation process for CT scanners from all manufacturers. 2) Appreciate how the patients' size, shape, and position in the gantry can affect the tube current modulation result. 3) Understand how the consistency of image quality can depend on the tube current modulation function.
The lecture will focus on understanding and exploiting the nuances of tube current modulation.
Automatic Tube Current Modulation (TCM) is often suggested as appropriate method for reducing radiation dose during clinical CT exams. Because the process is automated, the responsibility for the resulting technical parameters often seems to fall on the scanner software. However, there are several detailed aspects of all TCM systems that require special attention, and some nuances that are critical to understand in order to achieve the optimal outcome.
The role of the technologist in understanding and overseeing TCM application in clinical practice will be explained using specific examples.
