| Abstract: | Objective To study the technique of hi-frequency annulus array to overcome the disadvantage of linear-scan that it can focus on one dimension, and improve all orientations resolution, so the technique of digital imaging can improve the signal-to-noise, the quality of imaging and the detective rate. Methods Design hi-frequency annulus array immersion rotary ultrasonic probe and transmit-receive circuit, process the signals by AD9271 and deal with the digital signal. Results Detect the signals by hi-frequency annulus array digital ultrasonic, collect and analyze the signal of echo, result show that the hi-frequency annulus array digital ultrasonic can improve the detective rate of diseases. Conclusion The technique of hi- frequency annulus array digital ultrasonic is a effective method to diagnose eye and galactophore diseases. |
