Embodiment Construction

[0043] 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. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0044] The present invention is based on the calculation and optimization of ultrasonic tomographic imaging data in a distributed system, and transmits the data received by the pre-designated array elements on the probe to the corresponding node server, so as to avoid the problem of a single server grabbing a large number of data packets and losing packets. The pre-designated receiving array ele...

Abstract

The invention belongs to the field of ultrasound imaging large data volume processing and discloses an ultrasound tomography calculation optimization method and system based on a distributed system. The method comprises the steps of: preparation: arranging the distributed system comprising X distributed node servers and allowing array elements of a probe to correspond to the appropriate node servers, wherein the quantities of the array elements corresponding to the node servers are equal; and data acquisition and storage: conducting filtration preprocessing on received signals after acquiringall the signals, and conducting image reconstruction, wherein the image reconstruction comprises the steps of independent reconstruction of each node and major node server integration. The method andthe system process the ultrasound signals (acquired by the array elements) received by an ultrasound tomography system by using a distributed cluster system schema and the multinode servers based on aprinciple of a synthetic aperture focusing technique (SAFT), and can solve the problems of large data volume, long image reconstruction time and the like of the ultrasound tomography system.

Description

technical field [0001] The invention belongs to the technical field of large data volume processing of ultrasonic imaging, and more specifically relates to a method and system for optimizing calculation of ultrasonic tomographic imaging based on a distributed system, which can effectively handle and improve the problem of large data volume calculation of an ultrasonic tomographic imaging system. Background technique [0002] The ultrasonic tomography system refers to the measurement of the projection data of the object under the irradiation of ultrasonic waves through ultrasonic equipment without damaging the internal structure of the research object, and the two-dimensional or three-dimensional ultrasonic images can be reconstructed by using these data. Ultrasonic detection has the advantages of good directivity, low price, harmless to the human body, and easy to carry equipment. Therefore, the detection technology using ultrasound as the emission source instead of ray to ir...
