Superconducting magnetic resonance imaging machine used for breast disease diagnosis, and construction method and use thereof

Abstract

The invention discloses a superconducting magnetic resonance imaging machine, and a construction method and a use thereof. The superconducting magnetic resonance imaging machine of the invention comprises imaging areas, at least one vacuum insulation cover, a main magnet and a low-temperature cooling system, wherein the main magnet generates magnetic fields in the imaging areas; the low-temperature cooling system is connected with the vacuum insulation cover; a low vacuum space is formed and a lower-temperature heat conducting plate and at least one high vacuum inner cover and high vacuum outer cover are arranged inside the vacuum insulation cover; the vacuum insulation cover at least provides one imaging area; at least one superconducting radio frequency coil is arranged inside the low vacuum space and connected with the low-temperature heat conducting plate; and the low-temperature heat conducting plate is connected with the low-temperature cooling system through a heat pipe to realize and maintain the lower temperature condition of the superconducting radio frequency coil. The construction of the vacuum insulation cover is suitable for the imaging of the following body parts: breasts, knees, wrists, feet, a neck and a head. The invention can improve the magnetic resonance imaging quality and achieve a high signal-to-noise ratio in the imaging areas.

Description

technical field

[0001] The invention relates to a superconducting magnetic resonance imaging apparatus, and also relates to a construction method and application of the superconducting magnetic resonance imaging apparatus. Background technique

[0002] Magnetic resonance imaging is a non-invasive medical imaging technology, which is widely used in clinical medicine and brain function research. Because the magnetic resonance imager can image various tissue structures, especially the ability to distinguish soft tissues due to differences in water content, it provides useful information for doctors to diagnose. Almost all parts of the human body are suitable for imaging, such as the nervous system, musculoskeletal system, cardiovascular system, digestive system, and genitourinary system. This technology is particularly beneficial for early detection and treatment of stroke, real-time observation of cardiovascular function, and diagnosis of tumors and cancers. In addition, it ...
