Acquisition Thickness - Video Lesson

Everyone likes to talk about how fast a CT scanner is, especially nurses. And when people talk about that, We always talk about the number of slices or the number of detector rows, but there is another variable that affects the acquisition rate. And that is the acquisition thickness of the individual detector rose. Here's an example of a very typical teen slice detector row. Each of these rows are the same size and they all measure one millimeter. But I bet you didn't know that detector rows can be functionally combined together to increase the acquisition rate. Which would be good because that would decrease our scan time. So what does it mean to functionally combine the detector rows together? Well, here's one example. We could combine two detector rows and make them functionally one detector row. And that's exactly what we've done with this detector array.
