使用雙能、多能或光子計數(shù)設(shè)置測試不同類型的 CT 模式

測試多能光譜 CT 協(xié)議和后處理技術(shù)

分解碘和鈣酸水平

該模型旨在通過雙能、多能或光子計數(shù)設(shè)置測試不同類型的 CT 模式。模體由一個可拆卸/獨立的頭部模體（? 160 mm圓柱體）組成，帶有10個孔（? 25 mm）以容納不同的刀片和一個橢圓形（QRM-10150）或可選的圓形（QRM-10151）主體，配備9個孔。閥體和頭部由水當量材料（CTwater）制成。

QRM-10150多能模體配備了一套 26 個插入物，包括富含多種造影劑（水+碘、脂肪+碘）以及鈣（水 + 羥基磷灰石鈣）的棒，每種材料具有不同的濃度。此外，還包括水和軟組織等效插入物（脂肪，肝臟，大腦 - ICRU報告44和46）。為所有材料提供質(zhì)量密度、濃度和電子密度。

不同的ICRU組織和釓插入物可作為選項提供。

Test different types of Multi-Energy,

Dual-Energy and Photon-Counting CT

Protocols.

Perform System QA on DECT and PCCT

systems.

Investigate water and fat enriched

with iodine and calcium.

The phantom is designed to test different types of CT modalities with dual-energy, multi-energy or photon-counting setups.

Image acquisition and image processing at multiple energy levels is improving visualization for computed tomography. The QRM Multi-Energy QA phantom is ideally suited to test multi-energy spectral CT protocols and post-processing techniques.

The phantom consists of a removable/stand-alone head phantom (? 160 mm cylinder) with 10 holes (? 25 mm) to house different inserts and an oval (QRM-10150) or an optional circular (QRM-10151) body, equipped with 9 bores. Body and Head section are made of water-equivalent material (CTwater).

The phantom is equipped with a set of 26 inserts including rods enriched with several contrast media (water+iodine, adipose+iodine) as well as calcium (water+calcium hydroxyapatite), each material with different concentrations. Additionally, water- and soft tissue-equivalent inserts (adipose, liver, brain - ICRU Report 44 and 46) are included. Mass density, concentration and electron density are provided for all materials.
