Synchronous acquisition and playback method for nuclear magnetic resonance images

Abstract

A synchronous acquisition and playback method for the nuclear magnetic resonance images comprises the following steps: acquiring first image information of a patient by utilizing a nuclear magnetic resonance instrument, wherein the first image information is analog signal information; carrying out hash coding on the collected first image information, converting the first image information into digital abstract data, and adding a timestamp field; adding the receiving time and date information of the digital abstract data file into the timestamp field, and encrypting; and enabling the image display device to decrypt the encrypted digital abstract data file to obtain second image information of the patient, the second image information being digital signal information, then restoring a nuclear magnetic resonance image of the patient and a timestamp of the nuclear magnetic resonance image based on the second image information of the patient, and performing synchronous playback through a display of the image display device. According to the scheme, the memory consumption and the storage space are reduced by adopting hash coding, the transmission speed is high, the unique identifier is established for each nuclear magnetic resonance image by adding the timestamp field, and the identification accuracy of the nuclear magnetic resonance images is improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for synchronous acquisition and playback of nuclear magnetic resonance images. Background technique [0002] Nuclear magnetic resonance imaging is based on the principle of nuclear magnetic resonance (Nuclear Magnetic Resonance, referred to as NMR). According to the different degrees of attenuation of the energy released in the process of nuclear magnetic resonance in different structural environments inside the material, the emitted electromagnetic waves are detected by applying an external gradient magnetic field. Knowing the position and type of the nuclei that make up the object, based on this, the structure image inside the object can be drawn.

Problems solved by technology

[0003] Compared with CT and X-ray, MRI technology has many significant advantages, but MRI technology takes a long time to acquire images, and the acquired images occupy a relatively large memory space, and it is difficult to synchronize them. When taking an MRI image of a patient, there are problems such as difficult retrieval, long extraction time, and non-unique extraction results, which greatly limit clinical applications
