GAMMA DISTORTION

Phantom for Gamma Camera image quality

Description

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
