Nuclear magnetic resonance imaging device for heart and examination method of nuclear magnetic resonance imaging device

Abstract

The invention relates to medical examining equipment, in particular to a nuclear magnetic resonance imaging device for a heart and an examination method of the nuclear magnetic resonance imaging device. The nuclear magnetic resonance imaging device comprises a sliding bed board (2), wherein the sliding bed board (2) slides along a bed board track (4); a protecting cover (1) is connected onto the sliding bed board (2); a scanning coil (5) is arranged on the inner wall of the protecting cover (1); the sliding bed board (2) is arranged in the protecting cover (1); the scanning coil (5) and the sliding bed board (2) are in sliding connection; in addition, the sliding direction of the sliding bed board (2) is identical with that of the scanning coil (5); besides, semicircular electromagnetic shielding devices (8) are connected to two sides of the front part of the sliding bed board (2) through a sliding block. The nuclear magnetic resonance imaging device and the examination method, disclosed by the invention, have the beneficial effects that the convenience and the safety in operation are realized; a patient in whom a heart pacemaker is planted is prevented from magnetic field interference, and the problem that the patient in whom the heart pacemaker is planted cannot perform nuclear magnetic resonance imaging is solved.

Description

technical field [0001] The invention relates to the technical field of medical inspection equipment, in particular to a cardiac nuclear magnetic resonance inspection device and an inspection method thereof. Background technique [0002] NMR is a physical process in which the magnetic moment of an atomic nucleus whose magnetic moment is not zero undergoes Zeeman splitting at the spin level under the action of an external magnetic field, and resonantly absorbs radio frequency radiation of a certain frequency. NMR has become a common wireline logging service that has been widely used to evaluate rock properties and fluid properties. NMR measurements are typically made by precessing the magnetic moments of nuclei in the formation about an axis. By applying a polarized strong static magnetic field to the sample, the proton spins are aligned in a direction parallel to the applied field, forming an axis around which the nucleons precess. A series of radio frequency pulses are the...
