型號(hào)：Number RS-250 RSD模體 

廠家：美國(guó)RSD公司, Radiology Support Devices

人型；

頭骨周圍塑造；

檢查的重要物理參數(shù)；

提供真實(shí)系統(tǒng)檢測(cè)；

理想的訓(xùn)練工具；

以聚碳酸酯作為構(gòu)成材料方便平行或縱軸垂直。

A部分：鋁合金板，0.4毫米厚，在一個(gè)45度角的設(shè)置下，測(cè)量光束寬度和切片厚度。

B部分：該劑量部分，提供病人曝光控制，實(shí)際病人掃描前內(nèi)部異常劑量檢查。能夠滿足TLD的相應(yīng)的要求。

C部分：圓柱瘤建立分級(jí)大小和高密度分辨率，低對(duì)比度分辨率和顯示部分束平均影響。

D部分：模擬人的部分提供了實(shí)際聽小骨在有空氣對(duì)比的內(nèi)耳，和在有斷裂的骨頭。小腫瘤后顱窩被放置在一個(gè)地方，這個(gè)地方許多掃描都存在困難。

E部分：直徑為1/4-in的鋁桿位于模體的縱軸線，檢查一般路線對(duì)齊，和“干水“給出了一個(gè)真實(shí)的“噪聲檢查”。

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."
