Automatic Image Quality Scoring Software for CBCT applications

The DVT_AP associated QA software automatically evaluates all parameters which are essential for the assessment of imaging quality of CBCT equipment.

The interface is specifically designed for technical acceptance or commissioning tests and complies with DIN 6868-161.

The software is easy to use. It provides a walkthrough function and assists users to carry out the QA test.

The QUART_Tec stores the result of each single test in its internal data bank. In addition, a protocol print-out function is provided for matters of documentation (hardcopy) and later reference.

The software evaluates the following paramaters:
  • Nyquist Frequency (NF)
  • Contrast
  • Noise
  • Contrast-to-Noise Ratio (CNR)
  • Homogeneity / Image Uniformity
  • Modulation Transfer Function (MTF) at 10 % and 50 %
  • Artefacts, Image Flaws
  • Patient/Phantom Positioning Accuracy
  • Geometric Accuracy
  • Automatic System Indicator / Acceptance Indicator (as per DIN 6868-161)
