CTIQ
The TO CTIQ Image Quality phantom is designed for use with CT (Computed Tomography) units. TO CTIQ comprises a PMMA cylinder with recesses to house test inserts, and has been designed to nest within the TO CTDI body.
When used in conjunction with TO CTDI, this phantom enables the following QA tests to be carried out:
CTAEC-50
CTAEC-50 (Computed Tomography Automatic Exposure Control) phantom is used for constancy testing of CT AEC systems.
CT TE
Suitable for both kV and MV energies, TE is a tissue equivalent phantom consisting of a water equivalent nested head and body phantom each with 8 holes to house interchangeable inserts of different tissue equivalent materials as follows:
CBCT-150
CBCT-150 phantom is used for constancy testing of CBCT and 3D-Fluoroscopy systems.
TO CTDI
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) and the other represents the body (320mm diameter).
TO CTDI is heavy and as such is provided in a tough case with wheels and telescopic handle.
TO CTDI Plus
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).
TO CTDI plus is heavy and as such is provided in a tough case with wheels and telescopic handle.
Quattro
QUATTRO is a programmable 3-axis respiratory motion simulation phantom comprising a
motion arm and semi-anthropomorphic, tissue equivalent chest phantom and software.
QUATTRO enables three simultaneous types of motion:
Vertical motion for breathing surrogate motion
e.g. reflective block on Varian RPM
Horizontal motion for inserts within the phantom to be imaged/treated
e.g. simple ‘tumour’, TLD/film dosimetry, PET ‘lung’ insert, etc
Twist motion of the horizontal insert providing continuous rotation enabling different outward and return path for simulated tumour inserts.
SedentexCT IQ
SedentexCTIQ consists of a PMMA cylinder (160 mm diameter) with recesses to house test inserts (fig. 1). Within the body of the cylinder are features for the following tests:
CTAEC-25
CTAEC-25 (Computed Tomography Automatic Exposure Control) phantom is used for constancy testing of CT AEC systems.

CTDI Holder
Holder for Leeds Test Objects’ TO CTDI & TO CTDI plus phantoms, which enables hanging of the TO CTDI off the edge of its carry case. The holder has been carefully designed to allow for suspension of the phantom over the couch end, ensuring balance and rigidity.
Please note: This accessory requires screw holes in the CTDI phantom to fasten to the holder – please mention if this is required at the time of order. Modification of existing phantoms is available upon request.
