Embodiment Construction

[0052] A small bench-top comprehensive test phantom for MRI quality control, such as Figure 25 As shown, it includes a housing in which a test liquid and independent modular test modules are provided, and each module includes its outer shell and corresponding test pieces disposed therein.

[0053] The test modules include a three-dimensional test module, a chemical shift test module, a motion test module, a coil probe uniformity and linearity test module, a layer thickness test module, a relaxation test module, a contrast resolution test module, a positioning test module, a geometric Distortion test module and simulated mouse test module.

[0054] The three-dimensional test module is as Figure 4-7 As shown, the test piece is in the shape of a cube, with nine circular through-holes perpendicular to the surface on each surface. The circular through-holes are regularly arranged in three rows and three columns, and the circular through-holes on each surface are not connected to...

Abstract

The invention discloses a small-sized desktop type magnetic resonance quality control and comprehensive test phantom which comprises a shell, wherein a test liquid and an independent modular test module are arranged in the shell; and the test module comprises a three-dimensional test module, a layer thickness test module, a relaxation test module, a contrast resolution test module, a location test module and a geometric distortion test module. The small-sized desktop type magnetic resonance quality control and comprehensive test phantom is characterized by further comprising a chemical shift test module, a movement test module and a coil probe uniformity and linearity test module. The phantom is applicable to the test of small-sized desktop type animal imaging magnetic resonance apparatuses and magnetic resonance imaging systems, and has the advantages of multiple parameters, high precision, combination type and flexible pore diameter design.

Description

1: Technical field [0001] The invention relates to a small desktop magnetic resonance testing device, in particular to a quality control comprehensive test phantom specially used for small desktop magnetic resonance. Two: background technology [0002] The quality of small desktop MRIs should be calibrated and tested during delivery and daily use to achieve the accuracy required for equipment testing. Small desktop nuclear magnetic resonance equipment is often used in teaching experiments, small animal imaging, material analysis, food and industrial testing. Because the application range of small desktop magnetic resonance imaging systems or magnetic resonance analyzers is different from that of large medical magnetic resonance imaging systems, they have narrow apertures, imaging Or analyze the characteristics of short distance and small imaging objects. This makes the quality control test phantom of the existing medical magnetic resonance imaging system unable to be used i...
