Abstract

There are presented results of ultrasound radio-frequency signal sampling and processing to synthesize B-scan maps and evaluate two-dimensional visualization of ultrasound signal parameters. Our source of signal was ultrasound echoscope Mentor AdventTM A/B with mechanical scanning transducer of 11 MHz. Radio-frequency signal was digitized with digitizer Picoscope 5203. Amplitude and frequency based parameters were used for mapping B-scan ultrasound images. Standard phantom with axial resolution targets was used for the evaluation of mapping performance. We conclude that the signal processing and image transformation implemented in Matlab programs provide adequate two-dimensional mapping of B-scans. The usage of mean instantaneous bandwidth of radio frequency echoscopic signals enables to improve lateral resolution. Ill. 6, bibl. 11 (in English; summaries in English, Russian and Lithuanian).
