人型;
头骨周围塑造;
检查的重要物理参数;
提供真实系统检测;
理想的训练工具;
以聚碳酸酯作为构成材料方便平行或纵轴垂直。
A部分:铝合金板,0.4毫米厚,在一个45度角的设置下,测量光束宽度和切片厚度。
B部分:该剂量部分,提供病人曝光控制,实际病人扫描前内部异常剂量检查。能够满足TLD的相应的要求。
C部分:圆柱瘤建立分级大小和高密度分辨率,低对比度分辨率和显示部分束平均影响。
D部分:模拟人的部分提供了实际听小骨在有空气对比的内耳,和在有断裂的骨头。小肿瘤后颅窝被放置在一个地方,这个地方许多扫描都存在困难。
E部分:直径为1/4-in的铝杆位于模体的纵轴线,检查一般路线对齐,和“干水“给出了一个真实的“噪声检查”。

- Polycarbonate baseDimensioned For Scans Parallel or Perpendicular to LongitudinalAxis
SECTION A: Aluminum plates, 0.4mm thick, set at a 45°angle, measure beam width and slice thickness.
SECTION B: The dosimetry section providespatient-exposure controls, and checks on abnormal internal dosesbefore actual patient scans. Customization to accommodate TLD withrods or chips is available.
SECTION C: Cylindrical tumors of graded sizes andradiodensities establish high and low-contrast resolution anddemonstrate partial beam-averaging effects.
SECTION D: The anthropomorphic section provides actualauditory ossicles in an air-contrast inner ear and a fracturedpetrous bone. Small tumors in the posterior fossa are placed in anarea which most scanners image with difficulty.
SECTION E: 1/4 Inch diameter aluminum rod on thephantom's longitudinal axis, checks general alignment, and"DryWater" gives a realistic "noise check."
