Flouroscopy Flashcards
Real time image is usually considered to be ___ fps
30 FPS
Use ___ beam in conjunction with digital image acquisition
Pulsed xray beam
Allows angiography systems to provide lower dose operation while still delivering high inage contrast
Copper filtration with lower kV values
Collimators used for flouroscopy
Image intensifier based system
Flat panel flouroscopy
Circular diaphragm
Rectangular collimation
Keeps air out and allow unimpeded electron flow
Vacuum housing
Converts the absorbed incident xrays into light
Input layer
Accelarates ane focuses the electrons emitted by the input layer onto the output layer
Electron optics system
Converts the accelerated electrons into a visible light image
Output phosphors
Is the product of the total air kerma exiting the xray tube housing and the area of the beam and hence the units are mGy-cm2
