Embodiment Construction

[0058] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0059] In order to solve the problems existing in the prior art, a new volume data synthesis method is proposed in the embodiment of the present invention: obtain the basic slice direction of the synthesized image, and based on the basic slice direction of the synthesized image, obtain each An outer bounding box of the input volume data; after that, each input volume data is re-sampled in the outer bounding box of each input volume data, and it is determined that the overlapping area between the re-sampled volume data has The translation parameters of the maximum similarity; finally, according to t...

Abstract

The invention discloses a method for synthesizing volume data, which comprises the following steps of: acquiring a basic slice direction of a synthesized image; acquiring an outer bounding box of each input volume data based on the acquired basic slice direction of the synthesized image; re-sampling each input volume data in the outer bounding box of each input volume data; determining that an overlapping region between the re-sampled volume data has a translation parameter of maximum similarity; and synthesizing the re-sampled volume data into one volume data according to the determined translation parameter to acquire a synthesized image. The invention discloses a device for synthesizing the volume data at the same time. The method and the device can synthesize the volume data with random slice direction.

Description

technical field [0001] The invention relates to magnetic resonance imaging technology, in particular to a volume data synthesis method and device in a magnetic resonance imaging system. Background technique [0002] Due to the hardware limitation of the magnetic resonance system, in practical applications, when the magnetic resonance system is used for scanning imaging, it is usually not possible to acquire the scanning images of the whole body at one time. Therefore, multiple acquisitions are required to obtain multiple overlapping images. The volume data of the area, and then synthesize these volume data into a volume data in a certain way, so as to obtain a virtual large field of view (Virtual Large Field of View), which can be used for the diagnosis of some systemic diseases, such as respiratory system and vascular system. [0003] Currently, synthesis techniques of volumetric data with different slice orientations are widely used in clinic. A typical application is to...
