Ultrasonic patch and system and method for positioning ultrasonic patch

The invention provides an ultrasonic patch (710) comprising a first array set (720) comprising a primary transducer array (730) having a first orientation and a second array set (740) comprising at least two secondary transducer arrays (750) wherein each secondary transducer array has an orientation different from the first orientation. The second array group is arranged such that at least two secondary transducer arrays are disposed on either side of the primary transducer array. The first array group or the second array group may be used to capture preliminary ultrasound data for locating an ultrasound patch. The primary transducer array and the at least two secondary transducer arrays may include a CMUT, and the ultrasound patch may include a flip-chip connection. Systems and methods for positioning an ultrasound patch on a surface of a subject are also disclosed. 本发明提供了一种超声贴片(710)，其包括第一阵列组(720)和第二阵列组(740)，第一阵列组包括具有第一取向的初级换能器阵列(730)，第二阵列组包括至少两个次级换能器阵列(750)，其中每个次级换能器阵列具有不同于第一取向的取向。第二阵列组被布置成使得至少两个次级换能器阵列被设置于
