Description
Technical Field
The application relates to a magnetic resonance radio frequency receiving coil and an image post-processing method.
Background
Cerebrovascular diseases such as apoplexy, apoplexy and the like account for the first causes of death of Chinese people, and blood vessel examination is relatively neglected, so that early prevention and treatment opportunities are missed for some high-risk groups. Which kind of examination can accurately assess whether there is a risk of embolism in the head and neck vessels? Nuclear magnetic resonance is currently the most well-established examination item. Magnetic resonance enables the identification of the type and composition of atherosclerotic carotid plaque, such as lipid or necrotic lipid nuclei, inflammatory tissue, hemorrhage, thrombus, and fibrous cap morphology.
The magnetic resonance imaging system refers to a type of imaging equipment for medical examination, which is made by using a magnetic resonance phenomenon, and is a high-end large-scale medical examination equipment. There are imaging sequences at a number of different settings of magnetic resonance, such as T1-weighted, T2-weighted, proton-weighted sequences, and so forth. The contents of various sequences focused on observation are different, such as the texture, water content, bleeding or not, tumor cell density, whether pus or old bleeding exists or not, and the like, which are respectively displayed, each sequence can provide a part of information, and doctors often need to integrate the image information displayed by different sequences to judge the position and the state of illness of the focus of patients more comprehensively.
However, different sequences have different physical properties and specific requirements, and different slice directions, layer numbers, layer thicknesses, resolutions, and the like, and therefore, it is often necessary to compare, locate, and track some position points in different sequence images to determine the disease property of the position points. Especially for some multi-point focus and continuous focus, the focus characteristic is different at each place, so the positioning, comparing and tracking between different sequences is very important.
The atheromatous plaque in the blood vessel of the head and neck is the situation, because the trend of the blood vessel is bent and curved, the bifurcation is also more, the position distribution of the atheromatous plaque is relatively dispersed, and the judgment of the easy shedding performance of the multi-point plaque and the positioning of the multi-point plaque are both needed, thereby having considerable difficulty in diagnosis.
So doctors often need to assist diagnosis by means of post-processing software which is installed on a high-performance workstation (host computer). After the magnetic resonance machine completes the required clinical examination sequence, the images are imported into a workstation, and then the imported magnetic resonance images are analyzed by adopting special post-processing software.
However, as mentioned above, even if the same tissue point of the patient is the same tissue point, due to the different parameters adopted by the different sequences, the positions of the tissue points appearing in the image are generally not in the same layer and the same position, which brings great difficulty to the post-processing software, the calculation amount required by the software is very large, and simultaneously, the doctor is required to provide much additional processing information to the software, thereby greatly increasing the work difficulty and the work amount of the doctor.

And establishing a three-dimensional space coordinate system by using the four developing points as reference points by means of image processing software. Obviously, since the positions of the respective development points are fixed during the magnetic resonance imaging, the three-dimensional space coordinate system in each magnetic resonance image has the same positional relationship. And positioning, tracking and comparing specific pixel points in different sequence magnetic resonance images by using the three-dimensional space coordinate system as reference by the aid of the image processing software.
