Computer-detected diameters of small coronary vessels are often severely overestimated due to the influence of the imaging system point spread function and the use of an edge operator designed for. Fluoroscopy is a medical imaging technique using a constant source of X-ray to show a live presentation of the inner structures of the human body.

Fluoroscopy is similar to radiology in the sense that it uses X-ray technology and the detectors, but differs in the X-ray exposure time, and the. Cite this chapter as: Pfaff J.M., Whiting S., Eigler N.E., Forrester J.S.

The proximal end of the catheter is attached to computerized ultrasound equipment. It allows the application of ultrasound technology, such as piezoelectric transducer or CMUT, to see from inside blood vessels out ICDCM: The use of ultrasound for various diagnostic techniques in medicine continues to increase in popularity and complexity.

It seems possible that the prediction of the National Science Foun­ dation that ultrasonic techniques may be used as frequently as X-ray techniques by the end of the decade may.
