RS-250头部CT模体

RSD RS-250头部CT模体，RS-250头部彷真CT模体详细介绍：

RSD RS-250 头部CT模体，RS-250头部彷真CT模体特点：
拟人化
被铸造的Acround头骨
检查重要的物理参数
提供真实的系统检查
理想的培训
聚碳酸酯底座的尺寸适用于与纵轴平行或垂直的扫描



A部分： 0.4毫米厚的铝板设置45°角，测量光束宽度和切片厚度。  
 RS-250 A部分



B部分：剂量测定部分提供患者暴露控制，并在实际患者扫描前检查异常内部剂量。定制容纳TLD与棒或芯片是可用的。  
 RS-250 B部分


C部分：分级大小和放射性的圆柱形肿瘤建立高对比度和低对比度分辨率，并显示部分光束平均效应。    
RS-250 C部分


D部分：拟人部分在空气对比的内耳和骨折的岩骨中提供实际的听觉小骨。后颅窝小肿瘤被放置在大多数扫描仪难以成像的区域。  

 RS-250 D部分


E部分：人体模型纵轴上1/4英寸直径的铝棒，检查一般对准情况，“干水”给出了一个现实的“噪音检查”。



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."
