CT AEC

by | Nov 4, 2016 | Leeds CT

CT AEC (Computed Tomography Automatic Exposure Control) phantom is used for constancy testing of CT AEC systems.

CT AEC includes:

  • 11x PMMA ellipses of 25mm thickness (different height and width so that they can be re-configured into any order)
  • Each step contains a central hole to accommodate a choice of:
    – Blank inserts for AEC checks (supplied)
    – Tubes to accommodate pencil ion chambers for dosimetry (supplied)
    – SEDENTEXCTIQ image quality inserts (available separately)
  • 2 x sturdy end plates with integral carry handles and adjustable height and length nylon supports
  • Spirit level and pigment-filled centre markings (for easy and reproducible positioning)
  • Wheeled protective storm case with telescopic handle

This design is protected under Community Design Registration No. 002419572-0001

Also available with 50mm thick ellipses as CTAEC-50

AutoPIA

by | Nov 3, 2016 | Leeds Software

AutoPIA (Automatic Phantom Image Analysis) is a software for automatic recognition and analysis of test images of objects (phantoms) used to evaluate image quality. AutoPIA is able to quickly provide reproducible and objective quality indices for routine quality control processes aimed at optimizing the performance of an X-ray system.

AutoPIA automatically analyses a given digital image and quickly calculates objective, reliable, and reproducible indices to evaluate the performance of a radiological equipment. Then it stores the analysis results and provides control charts with baseline and threshold values in order to keep track of quality trends and abnormal conditions.

AutoPIA is currently able to recognize and analyze the following phantoms:

A 20 day demo licence for AutoPIA can be downloaded from the AutoPIA downloads page.

TO CTDI plus

by | Nov 3, 2016 | Leeds CT

TO CTDI plus permits the user to measure the dose index for computed tomography systems. The test object consists of three PMMA cylinders, one cylinder represents the paediatric head (100mm diameter), the second the adult head (160mm diameter) and the other represents the body (320mm diameter). The length of each cylinder is 140mm. Each cylinder contains holes large enough to accept a radiation detector, used to take the dose measurements.

There is a hole at the centre of the cylinders and one at each 90° interval, centred 10mm from the edge of the cylinder. This item is available as a nested phantom (the paediatric head phantom fits inside the adult head phantom which fits inside the body phantom).

TO CTDI plus enables the following tests to be made:

  • CTDI100 (centre)
  • CTDI100 (peripheral)
  • CTDIw (weighted CTDI100)
  • CTDIvol (weighted CTDIw)
  • CTDIfree air

TO CTDI plus is heavy and as such is provided in a tough case with wheels and telescopic handle.

Please note: a CTDI holder is now available for suspension of the TO CTDI plus over the couch end.
