Gamma Distortion

Rigid PMMA phantom for the quality control of geometric distortion and spatial resolution of gamma cameras.

The Gamma distortion phantom consists of a series of 1mm dia. 3mm deep holes at 80mm pitch which, when filled with activity, allows the user to perform:

  • Point-to-point measurement
    to ensure accurate representation of true distances in the image
  • Measurement of the point spread function (psf)
    at each point to determine spatial resolution, and its homogeneity across the entire FOV
