Magnetic resonance imaging coil device for leading and guiding ultrasound diagnosis and treatment of encephalopathy

Abstract

The invention discloses a magnetic resonance imaging coil device for leading and guiding ultrasound diagnosis and treatment of. The magnetic resonance imaging coil device comprises a fixed coil unit and a flexible coil unit, wherein the fixed coil unit comprises a half-cylinder-shaped coil fixing frame; a lower coil mounting cavity is formed in the cylinder wall of the coil fixing frame; a secondbirdcage radio frequency transmitting coil and a second multi-channel array receiving coil are arranged in the lower coil mounting cavity; the flexible coil unit comprises an insulation and thermal insulation cloth sleeve; an upper part coil mounting cavity is formed in the insulation and thermal insulation cloth sleeve; and a first birdcage radio frequency transmitting coil and a first multi-channel array receiving coil are arranged in the upper coil mounting cavity and the coil fixing frame is connected with the insulation and thermal insulation cloth sleeve through hook and loop fasteners.The magnetic resonance imaging coil device disclosed by the invention is simple in structure and convenient to use; normal work of an ultrasound helmet is focused; the coil is more close to the head of the patient, and adopts a working pattern of independently transmitting and receiving; the stimulation of radio frequency signals are more uniform, the receiving sensitivity of a stuffing factor ishigher and leading and positioning of magnetic resonance imaging are more accurate.

Description

technical field [0001] The invention relates to the field of focused ultrasound for clinical diagnosis and treatment of brain diseases and related medical devices, and in particular to a magnetic resonance imaging coil device for guiding focused ultrasound to diagnose and treat brain diseases. Background technique [0002] Magnetic resonance imaging has the characteristics of no radiation, non-invasive, non-invasive, multi-image types and high image contrast. It is applied to the internal structure of the human body to make it popular and extensive in medical clinical diagnosis. Hyperpolarization 129 Xe gas or 3 Gas MRI methods using He gas as a contrast agent can "light up" the lungs, and their nuclear spin polarization does not depend on the magnetic field of the MRI machine, however, methods that usually use proton imaging are related to the magnetic field strength , with higher image resolution and better image quality in a higher magnetic field environment. Therefore...
