Anthropomorphic Molded Around Skull Checks Important Physical Parameters Provides Realistic System Check Ideal For Training Polycarbonate Base Dimensioned For Scans Parallel or Perpendicular to Longitudinal Axis SECTION A:?Aluminum plates, .mm thick, set at a ° angle, measure beam width and slice thickness. SECTION B:?The dosimetry section provides patient-exposure controls, and checks on abnormal internal doses before actual patient scans. Customization to accommodate TLD with rods or chips is available. SECTION C:?Cylindrical tumors of graded sizes and radiodensities establish high and low-contrast resolution and demonstrate partial beam-averaging effects. SECTION D:?The anthropomorphic section provides actual auditory ossicles in an air-contrast inner ear and a fractured petrous bone. Small tumors in the posterior fossa are placed in an area which most scanners image with difficulty. SECTION E:?/ Inch diameter aluminum rod on the phantom's longitudinal axis, checks general alignment, and "DryWater" gives a realistic "noise check."
