Ultrasound breast imaging technique using two opposing transducer arrays

This paper presents a diagnostic ultrasound imaging technique that can be used in imaging protruding objects such as a human breast using two opposing array transducers. Images are obtained in both transmission and reflection modes using two opposing linear transducer arrays. In reflection mode, images are obtained from each of both transducer arrays, and are compounded to produce a B-mode image. Also, in transmission mode, speed of sound images are reconstructed. Experimental results with a phantom containing a cylinder of different speed of sound confirm that the proposed method is useful in obtaining compound as well as speed of sound images.
