ReplyDeleteSSSSHHHHHHH!!!! It's a SECRET!
Deleteamazing tech.
ReplyDeleteMesmerizing yes, but ct scanners are a tech born in the 70’s, no?
ReplyDeleteStill I’m certain enhancements have been integrated since 1978 when
I first witnessed one in operation.
CT and MRI look largely the same from outside. Have had one CT and five MRIs for various injuries. Don't sit near me, I guess...
ReplyDeleteCT scanners became commonly available in teaching hospitals around 1976. By 1980 many medium size community hospitals had one. The technology has advanced at an amazing pace driven in large part by the exponential increase in computing power. When I started scanning patients in 1980 it took 9.5 seconds to acquire a single slice of image data and 58 seconds for the computer to process it into an a 320 x 320 matrix image. It took 12-15 minutes to scan a head, double that for a contrast enhanced exam. It took 40-50 minutes to scan a typical abdomen. Now I can scan a head in less than 10 seconds and the images are processed and pressented in near real time. And the images are in a 1024 x 1024 matrix. The computer and software can process the data into any plane or point of view desired in near real time ad also produce 3D images. When I was first starting in imaging before I started doing CT I was an angio tech. A procedure requiring at least one MD, one or two nurses, and one or two technologists. A typical angiogram could take an hour to perform. Now more than 90% of angios are done by CT. One tech can do a head and neck angiogram by themselves in the middle of the night now in maybe 20 minutes. The technology is mind boggling. And techs are still considered "non professionals" and lumped in with housekeeping by the US Labor Department.
ReplyDeleteyep - I worked at GE (Good Enough) Healthcare building these for 15 years. in addition to the computing power Dan mentioned, we developed a detector material (which converts the x-rays to visible light and picked up by a photo-diode) that was minimum 100x faster than the previous material. the biggest drive in the industry was reducing "dose" wherever/however possible. amazing tech. amazing machines. Horrible leadership (at least for GE)
