TOR ABC

Beam Alignment Phantom

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 beam alignment and centring.

Used for Radiography or Fluoroscopy, enables the following checks to be made:

  • The correspondence of the light field with the effective radiation field.
  • The determination of the position of the central beam.
  • The central beam angle deviation from 90°, relative to the plane of the film/detector, is below a limit that beyond which the image quality would be adversely affected.

The TOR ABC is available on its own or with either the hanger vertical bucky jig or the suction vertical bucky jig.

*** A special variant of the vertical bucky jig is available for Siemens’ Vertix system. Please request at time of order ***

TO CTDI

A computed tomography dose index (CTDI) QA phantom consisting of nested adult head and body segments.

TO CTDI permits the user to measure the dose index for computed tomography systems. The test object consists of two PMMA cylinders, one cylinder represents the head (160mm diameter) which, when nested inside the the other, represents the body (320mm diameter). The length of each cylinder is 140mm. Each cylinder contains 13.0mm diameter holes and comes with two adaptors tubes to permit the use of either 8mm, 10mm or 13mm diameter radiation detectors, 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. TO CTDI includes nine PMMA pegs used to to fill the unoccupied holes and a phantom support for each size of cylinder.

TO CTDI has been designed in accordance with standards IEC 61223-3-5, IEC 61223-3-6 and IEC 60601-2-44.

TO CTDI enables the following tests to be made:

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

TO CTDI nested head and body phantom is supplied in a trolley case with a telescopic handle.

DSF SET

DSF Imaging Set Test ObjectA set of phantoms for routine, commissioning and annual image quality QA for digital subtraction fluoroscopy systems.

A set of four test objects, the DSF set is supplementary to the SFS set of test objects and checks those parameters which are particularly relevant to DSF imaging. After mask images have been obtained the image content is changed by the manipulation of various plates.
 

TO 10

TO 10 Contrast Detail PhantomA contrast detail phantom for fluoroscopy systems.

These test objects are designed for quick quantitative assessments of image quality. The results can be plotted on a Threshold Detection Index Curve. TO 10 is intended for use with Fluoroscopy systems.
