Alignment phantom for MR/PET system

摘要

A phantom for co-registering a magnetic resonance image and a nuclear medical image is disclosed. The phantom includes a longitudinal member having a first end cap and a second end cap and a chamber contained within the longitudinal member. The chamber contains a fluid for producing a first image using a first imaging modality. The phantom further includes a first rod disposed within the chamber of the longitudinal member. The first rod contains a radioactive substance for producing a second image using a second imaging modality.

主权项

1. A method of testing an integrated multimodality medical imaging scanner, wherein magnetic resonance (MR) constitutes one of the modalities, comprising:
disposing a phantom within the scanner, the phantom comprising a plastic housing having a plurality of rods containing a radioactive substance along an axis of the plurality of rods to provide an image using a second imaging modality; operating magnetic resonance imaging features of the scanner; simultaneously imaging the phantom using the second modality imaging feature of the scanner; determining a coordinate system based on a line segment along a shortest path between rod pairs of the plurality of rods; and determining a quality measurement based on a measured length of the line segment.
