CR-DR 2 Flashcards
understanding of conventional film/screen
1.Uses film and intensifying screens in the image formation process.
2.Film is placed on one or two IS that emit light when struck by x-rays.
3.Film is processed with chemicals to convert latent image to manifest image.
4.Film is taken to a radiologist and placed on a light box for interpretation.
In medicine, one of the first use of digital imaging was the introduction of the__
CT SCAN
who introduced CT Scan
Godfrey Hounsfield 1970
second major milestone in medical imaging
CT Scan
earliest unit took several hours to acquire a single slice of information
few days to reconstruct raw data into recognizable image
CT Scan
introduced commercially for health care use in the early 1980s
- MRI
made it possible to capture the image digitally
Fluoroscopy
_____ and _____tubes allowed for the display of the dynamic image on TV
Plumbicon and VIdicon
easy converts to the digital world because the images created were simply frame-grabbed
Ultrasound & Nuclear Medicine
introduced the concept of moving images digitally during his experimentation with teleradiology in the 1950s
