TOR 18FG - Leeds Test Objects



TOR 18FG - Leeds Test Objects

TOR 18FG fluoroscopy phantom is a routine test object designed to be used quickly and easily on a regular basis (e.g. weekly/monthly) to provide an ongoing check of imaging performance, particularly those aspects which are most liable to deterioration. After an initial grey-scale check, image quality is measured simply by counting the number of details detected and the number of bar-patterns resolved in the image. An ongoing record of these numbers will reveal any trend towards deterioration in imaging performance.
Used for fluoroscopy and fluorography, enables the following checks to be made:
  • Monitor brightness and contrast level adjustment (highlight and lowlight details)
  • Resolution limit (0.5 to 5.0 LP/mm)
  • Low-contrast large-detail detectability (18 details, 8mm diameter)
  • Circular Geometry (Lead Circle)
Small F.O.V. TOR 18FG
We can supply smaller diameter field of view versions of TOR 18FG on request, with the same features as the standard phantom (ideal for mini C-arms).
