“…By exchanging the transmit and receive functions of the two transducer arrays, the range of angles over which data can be acquired is doubled compared to the case of using a single transducer array and a plane reflector [5], [6]. In order to reconstruct speed of sound images from the arrival time of received signals, the backprojection algorithm is employed [3]. The procedure used here is briefly explained.…”

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.

“…Kossoff et al (1973) have used the relative TOF method described above to make measurements of average speed of sound in the female breast. Extensions of this approach, by scanning the sound beam to obtain multiple TOF projections, make it possible to reconstruct tomographic images of the speed of sound in coronal planes through the breast (Greenleaf & Bahn 1981;Carson et al 1981;Glover & Sharp 1977;Koch et al 1983). Images so produced appear to provide information complementary to the echographic imaging process.…”

“…Each image has 128 ϫ 128 pixels of 1 mm 2 . The number of projections utilized for reconstruction (4,8,16, and 64) is indicated on top of each image. Observe that streak artifacts appear due to the number of projections used for image reconstruction being smaller than required (see text).…”
