基于256阵元环形阵列的乳腺反射成像系统设计
Design of Breast Reflection Imaging System Based on 256 Elements Ring Array
摘要
Abstract
As a new imaging detection method for breast cancer,ultrasonic computed tomography has the advantages of non-radiation and low cost.Most of the existing breast ultrasound imaging systems use lin-ear arrays,which require mechanical movement or rotation to obtain a complete slice image.There are certain difficulties and errors in practical operation.In this paper,a reflective ultrasound imaging system based on 256 elements ring array was designed.The common B-mode imaging was applied to the ring array imaging,and the implementation method of the time reversal imaging algorithm in the ring array background was derived.The feasibility of the reflective ultrasound tomography system based on circular array was preliminarily verified through simulation experiments and breast phantom measurements.Com-pared with B-mode imaging,the dimensional reconstruction deviation in time reversal imaging results can be reduced by a maximum of 24.4%.In addition,a human arm test was conducted to prove the feasibil-ity of this method in multiple parts of the human body.The research results of this study provide theoreti-cal basis and technical support for the construction of an ultrasonic imaging system based on ring array.关键词
