Conclusions from a test of multi-modal ultrasound tomography research system designed for breast imaging

Today, considering global development of digital technology, experts not only strive to perfect methods of conventional ultrasound echographic imaging of tissue structure (US), but also intensively develop other methods, focusing especially on ultrasound transmission tomography (UTT) (analogous to X-ray computed tomography CT) and reflection tomography (URT) (based on synthetic aperture method used in radar imaging). The two techniques combined with conventional echographic imaging can be used together in a specialized hybrid ultrasonic tomograph. The device scans the examined tissue, which is submerged in water, from all the angles around it, using a circular array of elementary piezoceramic transducers that are evenly arranged on the inner side of the array. This multi-modal tomographic imaging can be successfully used for early detection and diagnosis of malignant lesions in women’s breast tissue. This study presents and analyses the results of ultrasound tomography imaging of the internal structure of biological media and their phantoms using an ultrasound computer tomography research system. The obtained results show that, after the scanning process is accelerated making it possible to perform in vivo examinations, the developed method of multi-modal ultrasonic tomographic measurements of breast tissue can successfully be used to detect and diagnose focal lesions in women's breasts.
