Embodiment Construction

[0035] The present invention will be further described in detail in conjunction with the following specific embodiments and accompanying drawings. The process, conditions, experimental methods, etc. for implementing the present invention, except for the content specifically mentioned below, are common knowledge and common knowledge in this field, and the present invention has no special limitation content.

[0036] In the MRI scanning and compressed sensing reconstruction integration method of the present invention, during the data acquisition process of the magnetic resonance scanning, part of the K-space data that has been collected is used to reconstruct the image of the part of the K-space data using compressed sensing technology. With the progress of the MRI scan, other unacquired K-space data are continuously collected, and this part of K-space data is substituted into the reconstruction process, and compressed sensing technology is used to iterate to continuously optimiz...

Abstract

The invention discloses a method for integrating magnetic resonance imaging scanning and compressive sensing reconstruction. The method comprises the steps of collecting all data in a common-wave center area of a K space, collecting data outside an echo center area of the K space randomly, carrying out real-time image reconstruction through a compressive sensing technology according to the data of the common-wave center area of the K space and the randomly-collected data of the K space, improving the quality of reconstructed images continuously and displaying the reconstructed images in real time. The compressive sensing technology is utilized for reconstructing and displaying the magnetic resonance images in real time, the progress of the magnetic resonance imaging scanning can be observed in real time, the magnetic resonance imaging scanning can be ended in advance at any time according to the quality of the images, and the time for the magnetic resonance imaging scanning is effectively shortened. The invention further discloses a device for integrating the magnetic resonance imaging scanning and the compressive sensing reconstruction.

Description

technical field [0001] The invention belongs to the technical field of magnetic resonance imaging, and in particular relates to an integrated method of magnetic resonance imaging scanning and compression sensing reconstruction and a device thereof. Background technique [0002] Magnetic resonance imaging has the advantages of no damage, high contrast of soft tissue, and slices in any direction. It can not only provide tissue morphological information, but also reflect the functional characteristics and level information of tissues. Therefore, magnetic resonance imaging has been widely used in medical clinical diagnosis. . [0003] Compressed sensing, also known as compressed sensing and compressed acquisition, is a new signal processing technology developed after 2006. For signals that meet certain conditions, compressive sensing methods can use frequencies far lower than those required by the Shannon-Ninquist acquisition theorem for acquisition, and still recover the origi...
