Mammography/Technical Notes
From WikiLectures
- X-ray - the anode is made of molybdenum or rhodium, thanks to which mostly lower energy photons are produced. In addition, photons with higher energy are filtered out' = advantageous spectrum of radiation. Small foci in roentgence allow to capture even very small structures' (e.g. microcalcifications).
- Mammographic films - consist of a single-sided emulsion and an intensifying film that contains rare earth compounds (lanthanum, gadolinium), which will allow to reduce the radiation dose while maintaining resolution.
- Compression plate (tube) - breast compression makes it possible to reduce radiation dose, increase contrast, reduce motion blur and summation negatives.
- Special negatoscope - contains a high brightness aperture.
- Digital mammography - makes it possible to eliminate the disadvantages of conventional mammography (noise, lower contrast, higher dose of radiation, combination of film-enhancing film). Image editing and storage on a computer is an indispensable part of modern radiology.
