Computed Tomography Phantom

Products used in Computed Tomography:
Sedentex CT IQ: Within the body of the cylinder are features for the following tests; Noise/Uniformity - The lower section of the phantom is uniform PMMA (density 1.20 +/- 1.00%) Geometric Distortion - An array of 2.0 mm diameter, 3.0 mm deep Air gaps are uniformly pitched at 10.0mm intervals through one slice of the cylinder.Please click here to see the Data sheet.

Sedentex CT DI: The SedentexCT DI dose index phantom comprises a stack of PMMA plates forming a cylinder representing the adult head. Several types of detector system are catered for:
ionization chambers.
thermoluminescent detectors (TLDs).
gafchromic film.

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). 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, centered 10mm from the edge of the cylinder.Please click here to see the
Data sheet.

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 pediatrics 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 center of the cylinders and one at each 90° interval, centered 10mm from the edge of the cylinder. This item is available as a nested phantom (the pediatric head phantom fits inside the adult head phantom which fits inside the body phantom).
