PHANTOM FOR MAGNETIC RESONANCE IMAGING SYSTEM

摘要

A phantom for an MRI system is provided. The phantom includes a third layer, the third layer including a first structure and a second structure, the first structure including two adjacent wedge-shaped objects in opposite directions which do not generate magnetic resonance signals, the second structure includes a first module group pair, the first module group pair including a first module group and a second module group, the first module group and the second module group each including multiple modules which are identical to each other, aligned with each other and separated from each other by the same distance, and the first module group and the second module group are perpendicular to each other. The phantom for an MRI system can satisfy measurement of multiple image quality indices such as layer thickness and resolution at the same time, which saves a large amount of repetitive work and time.

1. A phantom for a magnetic resonance imaging system, comprising:
a third layer, the third layer comprising a first structure and a second structure, the first structure comprising two wedge-shaped objects which have sides adjacent to one another, do not generate magnetic resonance signals, and have sloping surfaces in opposite directions; wherein the second structure comprises a first module group pair, the first module group pair comprising a first module group and a second module group, the first module group and the second module group each comprising multiple modules which are identical to each other, parallel to each other and separated from each other by the same distance; and the first module group and the second module group are perpendicular to each other.
