This invention discloses a coherent electrical stimulation method for idiopathic scoliosis combined with exercise therapy, belonging to the field of electrical stimulation methods for idiopathic scoliosis. It aims to address the problem of how to dynamically adjust stimulation parameters based on individual differences to improve treatment efficacy. The method includes acquiring raw image sequences of the patient's spine through MRI scans, preprocessing the raw image sequences to construct a three-dimensional geometric model of the spine, configuring simulated electrical property parameters for the tissue structures, and then adding coherent electrical surface electrodes to the model. The electrode placement area on the three-dimensional geometric model of the spine is initially defined, and a coherent electrical stimulation signal is generated using a function generator. A comprehensive evaluation index value is calculated through finite element analysis to dynamically adjust the coherent electrical stimulation signal. Based on the coherent electrical stimulation signal parameters and its comprehensive evaluation index value, a coherent electrical stimulation scheme is determined, and ultrasound-guided technology is used to locate the electrode positions and implement coherent electrical stimulation therapy.

This invention relates to the field of ultrasound therapy technology, specifically to an ultrasound localization method based on low-field magnetic resonance imaging (MRI). The method addresses the issues of large equipment size and high cost in existing ultrasound targeting techniques. By introducing a parallel ultrasound scanning process during the initial MRI scan to obtain ultrasound echo data, which is then stitched together with the MRI data. Subsequently, during target area localization, the ultrasound echo data and MRI data are analyzed simultaneously, enabling accurate localization of the target area in the brain and identification of easily penetrable locations on the skull where ultrasound energy can pass through. Based on this, an ultrasound probe with better penetration is selected as the focusing probe, eliminating probes with low emission efficiency, thereby improving the efficiency of ultrasound localization. Furthermore, improvements to the model allow the examination process to be performed using a low-field MRI system, reducing system costs.

This utility model discloses a quick stretcher for magnetic resonance imaging (MRI), belonging to the technical field of MRI-assisted equipment. It includes a support plate made of non-magnetic material; the shape of the support plate matches the scanning bed; two non-magnetic zippers are provided at one end of the support plate along its length, the two zippers being parallel and extending along the length of the support plate; two lifting rods are located on both sides of the support plate along its length; the lifting rods are detachably connected to the support plate; the connection between the lifting rods and the support plate allows for patient transport. After the patient and support plate are placed together on the scanning bed, the lifting rods can be easily removed without affecting the MRI scan, eliminating the need for secondary handling. The structure is simple, easy to manufacture, and inexpensive. Simultaneously, the two non-magnetic zippers at one end of the support plate are opened during MRI head scanning, allowing the scanning bed to enter the gradient coils unimpeded for scanning, without the support plate obstructing the scan, thus facilitating MRI scanning of the patient's head.
