Catphan189主體低對比度模體和Catphan191頭部低對比度模體,Catphan低對比度模體是為MITA CT IQ任務(wù)組定義的低對比度成像評估而設(shè)計的。這些模體取代了之前的CCT183模體。
Catphan189主體低對比度模體和Catphan191頭部低對比度模體都有八個對比度桿在制造時評估在0.05％的密度或±0.5 HU的目標(biāo)值。對比度對象的對稱定位使得這些模體成為評估重建算法的強(qiáng)制選擇和評分尺度實驗的理想選擇。

The CCT189 (body) and CCT191 (head) Low Contrast Phantoms are designed for low contrast imaging buations as defined by the MITA CT IQ Task Group. These phantoms replace the earlier CCT183 phantom.
Both phantoms have eight contrast rods buated at manufacturing to be within 0.05% density or ±0.5 HU of target values. The symmetric bing of the contrast b make these phantoms ideal for conducting forced choice and rating scale experiments for buating reconstruction algorithms.
For further inbation please see the CCT189 and CCT191 MITA CT IQ Low Contrast Phantom Manual.
The CCT189 LC Body Phantom has the following contrast rods:
14HU contrast, 3mm diameter x 40mm length and 15mm diameter x 10mm length
7HU contrast, 5mm diameter x 40mm length and 15mm diameter x 10mm length
5HU contrast, 7mm diameter x 40mm length and 15mm diameter x 10mm length
3HU contrast, 10mm diameter x 40mm length and 15mm diameter x 10mm length
The CCT191 LC Body Phantom has the following contrast rods:
9HU contrast, 3mm diameter x 40mm length and 15mm diameter x 10mm length
7HU contrast, 5mm diameter x 40mm length and 15mm diameter x 10mm length
5HU contrast, 7mm diameter x 40mm length and 15mm diameter x 10mm length
3HU contrast, 10mm diameter x 40mm length and 15mm diameter x 10mm length
