USACIRS 007/007 ACT dose phantom

 

Product introduction:

All computed tomography systems require measurementCT Dose Index (CTDI), CIRS Each part of the CT dose phantom can provide individual dose information. When performing dose distribution measurements, the user can also measure large, small, and intermediate ranges of nominal fault section thicknesses.

Each phantom consists of a set of thickIt consists of a 15 cm solid PMMA thick sheet with a nested structure of 16 cm (head) and 32 cm (body) diameter. Thick radiographs of adults' heads are also suitable for pediatric body measurements. The thick plate of model 007A can measure pediatric head measurements up to 10 cm in diameter.

The diameter of the through hole is1.31cm accommodates a standard CT probe, and an acrylic rod is provided to plug holes when not in use. The acrylic rod is a 100mm diameter TLD rod.

Both the 007 and 007A models are manufactured to comply with FDA performance standard 21 CFR 1020.33, detailed measurement requirements.

USACIRS 007/007 ACT dose phantom product performance:

Abdomen, adult head, pediatric head configuration

PMMA thick sheet and plug density 1.19 g/cm3

13.1 mm diameter hole conforms to standard dose CT probe dimensions

NestedThick PMMA sheets reduce storage space

with allCT scanner compatible

Optional support stand007-01, can be used to suspend the CT dose phantom on the imaging plate, aligned along the axis of rotation of the X-ray tube. Such a phantom can be used to evaluate CT dose in a spiral mode or when an image plate is required, or an extended stroke of a wide beam. This setup can be used to address the dose approach described in TG111. An additional application of the support bracket is to allow the body to simulate continuous scattered radiation from the patient when using spiral CT for complete dose measurement inside and outside the examination room.
