TOR DEN conventional

by | Nov 5, 2016 | Leeds Dental

Leeds Test Objects′ TOR DEN conventional phantom is designed to be used to check the image quality performance of conventional dental x-ray systems. These tests should be carried out at acceptance to establish a baseline, and on a routine basis, keeping an on-going record of the test results, which will indicate any deterioration in performance.

TOR DEN conventional is used for units with conventional film-based image acquisition, and enables the following tests to be made:

  • Optical Density Constancy
  • Radiation Field Alignment
    ~ for Panoramic and Cephalometric tests only

The phantom is supplied with a positioning device, for TOR DEN conventional this is a magnetic jig. For systems with no magnetic receptor, a suction jig is also available. The TOR DEN phantoms are supplied in a tough case with a bespoke foam insert.

DENTEST

by | Nov 4, 2016 | Leeds Dental

Leeds Test Objects’ DENTEST is a routine test object, or medical imaging phantom, designed to be used quickly and easily on a regular basis (e.g. monthly) to provide an ongoing check of imaging performance, particularly those aspects which are most liable to deterioration. After an initial uniformity check, image quality is measured simply by counting the number of resolvable steps, contrast details and resolution meshes in the image. An ongoing record of these numbers will reveal any trend towards deterioration in imaging performance.

Used for dental radiography, DENTEST enables the following checks to be made:

  • Uniformity
  • Dynamic range
  • Low contrast resolution
  • Detector homogeneity
