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 ***

TOR ABC Phantom

PIX 13

Leeds Test Objects – PIX 13 phantom is designed to check the image quality performance of digital radiography X-Ray systems.

TO ANSI

Leeds Test Objects – TO ANSI is a patient equivalent phantom is used when checking the image quality performance of general radiography systems.

TO AEC

Leeds Test Objects – TO AEC is an X-Ray quality assurance phantom comprising a stack of PMMA plates which allow the user to check the consistency, repeatability and reproducibility of AEC system function.

Fluoro 4 & Fluoro 4-L

Leeds Test Objects′ FLUORO-4 phantom is designed to be used to check the image quality performance of digital and conventional fluoroscopy 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.

FLUORO-4 features the following test details:

Tube axis direction markings

Limiting spatial resolution (0.6 − 5.0 LP/mm)

Low contrast resolution details (8 x 10mm diameter details, depths 0.4 − 4.0 mm)

Dynamic range (17 different thickness Cu steps each with a central 4.0mm diameter detail, depth 2.5 mm)

kV test-area (Yb 0.78mm)

Unstructured inner area (center-marked)

Radiopaque numbers indicating dynamic range steps

FLUORO-4 should be used with either PMMA/Cu or Al attenuator plates (available separately).

The phantom is supplied in a soft protective carry bag.

Available in 2 Sizes:

FLUORO-4 (200x200mm)

FLUORO-4-L (300x300mm)

Conforms to standards:

DIN 6868-4

DIN 6868-150

PMMA/Cu Attenuator

A bonded PMMA and Copper attenuator consisting of 30mm PMMA and 1mm Cu.

25mm Aluminium Attenuator

Leeds Test Objects- Aluminium Patient-Equivalent Attenuator is designed for use when checking the image quality performance of general radiography systems.

21mm Aluminium Attenuator

Leeds Test Objects – 21mm Aluminium Patient-Equivalent Attenuator is designed for use when checking the image quality performance of general radiography systems.

DR-2

A set of test objects designed to be used quickly and easily to provide an ongoing check of imaging performance, particularly those aspects which are most liable to deterioration. An ongoing record of these numbers will reveal any trend towards deterioration in imaging performance.

Set includes:

TC 21 threshold contrast test object (144 details (12 sizes x 12 contrasts) Size range 11mm to 0.25mm, Contrast range 0.00025 to 0.930 @ 75kVp, 1.5mm Cu filtration)

TO M2 geometry test object (Cross ruler and grid for field size and light/X-Ray congruence, with beam centring tower)

TO MS5 mesh test object (50mesh – 0.20mm wire, 310micron aperture)

TO MTF (MTF edge with free software)

Resolution test object (0.5 to 5.0 LP/mm)

1.5 mm Copper filter x 1
