CT Head with 5 slices to test all parameters of computerized tomography 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, 0.4mm thick, set at a 45° 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: 1/4 Inch diameter aluminum rod on the phantom's longitudinal axis, checks general alignment, and "DryWater" gives a realistic "noise check." http://szwellcome.b2b168.com
