Embodiment 1

[0049] figure 1 It is a flow chart of a magnetic resonance scanning method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of performing safety monitoring on patients during magnetic resonance scanning. This method can be implemented by the magnetic resonance scanning system provided by the embodiment of the present invention. To execute, the device may be implemented in software and / or hardware. see figure 1 , the method specifically includes:

[0050] S110. Obtain a lying posture of the scanned object.

[0051] Wherein, the scan object refers to a patient who is going to undergo an MRI scan, and the patient needs to lie flat on the detection bed during the MRI scan. In this embodiment, optionally, the scan object is a pediatric patient. Compared with adult patients, pediatric patients can tolerate lower radiofrequency energy, which poses a greater safety risk during MRI scans. In particular, pediatric patients cannot cont...

Embodiment 2

[0074] image 3 It is a flow chart of a magnetic resonance scanning method provided in Embodiment 2 of the present invention. On the basis of the foregoing embodiments, the magnetic resonance scanning method is further optimized. Correspondingly, see image 3 , the method specifically includes:

[0075] S210. Acquire a scanned image of the scanned object according to a preset radio frequency sequence, and determine a lying posture of the scanned object according to the scanned image, wherein the energy of the preset radio frequency sequence is less than a preset energy threshold.

[0076]Wherein, the preset radio frequency sequence refers to a radio frequency sequence for quickly locating the scanning object, which has the characteristics of low energy and high speed. The scanned object is scanned and imaged through the preset radio frequency sequence, only to recognize the lying posture of the scanned object, and no pathological detection is required for the scanned object....

Embodiment 3

[0089] Figure 4 It is a flowchart of a magnetic resonance scanning method provided by Embodiment 3 of the present invention. On the basis of the above embodiments, a method for monitoring magnetic resonance scanning noise is provided before performing magnetic resonance scanning according to the radio frequency sequence to be scanned. . Accordingly, the method includes:

[0090] S310. Obtain the lying posture of the scanned object.

[0091] S320. Determine the radio frequency energy absorption rate distribution model according to the lying posture, the radio frequency sequence parameters to be scanned, and the prestored radio frequency energy absorption rate distribution database.

[0092] S330. Determine the radio frequency energy absorption rate distribution of the scanning object according to the radio frequency energy absorption rate distribution model and the calibration parameters of the radio frequency sequence to be scanned.

[0093] S340. If the radio frequency en...

Abstract

An embodiment of the invention discloses a magnetic resonance scanning method, a magnetic resonance scanning system and a computer readable storage medium. The method includes: acquiring a lying posture of a scan object; determining a radio-frequency energy absorption rate distribution model according to the lying posture, to-be-scanned radio-frequency sequence parameters and a pre-stored radio-frequency energy absorption rate distribution database; determining radio-frequency energy absorption rate distribution of the scan object according to the radio-frequency energy absorption rate distribution model and to-be-scanned radio-frequency sequence calibration parameters; if the radio-frequency energy absorption rate distribution meets a first distribution condition, executing magnetic resonance scanning according to a to-be-scanned radio-frequency sequence, and acquiring magnetic resonance images of the scan object. The problem of limitation in application of an existing adult magnetic resonance imaging method to pediatric patients is solved, safety monitoring in magnetic resonance scanning of the pediatric patients is realized, safety magnetic resonance scanning of patients of different ages is realized, and methods for pathological tests of the pediatric patients are extended.

Description

technical field [0001] Embodiments of the present invention relate to magnetic resonance technology, and in particular to a magnetic resonance scanning method, system, and computer-readable storage medium. Background technique [0002] Magnetic resonance imaging technology is the most commonly used medical imaging technology for detailed visualization of the internal structure and function of the human body in radiology. , ligaments, and hyaline cartilage and other human tissues for high-resolution scanning imaging. During imaging with an MRI system, the patient absorbs some of the radio frequency energy emitted by the MRI equipment, which can cause heating of the patient's body tissues and other side effects such as body burns and changes in vision, hearing and nerve function. [0003] Infant patients, especially critically ill infant patients, are more likely to have side effects during MRI. Therefore, infants and young children have great limitations when seeking medica...
