Radiology QA Tools & Phantoms

ATOM MAX Dental & Diagnostic Head Phantom
The CIRS ATOM Max Dental and Diagnostic Head Phantom is a standard of reference for diagnostic radiology of the head. The phantom is designed to assist technical and clinical staff in the selection, monitoring, training and verification of scanning parameters common to most radiological procedures requiring fine anatomical details.

CT Dose Phantom
For all computed tomography systems, the Food and Drug Administration recommends measuring the CT Dose Index (CTDI). Each section of the CIRS CT Dose Phantoms can provide separate dose information. The user can also measure maximum, minimum and mid‐range values of the nominal tomographic section thickness when performing dose profile measurements.

Each phantom consists of a set of nesting 15 cm thick solid PMMA disks

AAPM CT Performance Phantom
The CIRS Model 610 AAPM CT Performance Phantom offers the user a single test object that measures ten distinct CT performance parameters. The phantom design is based on the guidelines presented in Report #1 of the American Association of Physicists in Medicine Task Force on CT Scanner Phantoms. The goals of report #1 were to “(1) define ‘performance’ of a CT scanner and (2) describe methods of performance testing through utilization of particular phantoms.”
