Abstract

The invention discloses a method for calibrating an ultrasonic scanner. Through the rotation axis and the θ axis perpendicular to the axis, it includes: rotating a transducer along the axis and collecting the first energy from the target reflection surface on the scanning plane. data; calculate the angle of the first maximum peak intensity from the first data; rotate the transducer 180° along the θ axis; rotate the transducer along the axis and collect second data from the same target reflective surface on the same scan plane; calculating the angle of the second maximum peak intensity according to the second data; and subtracting the angles of the two maximum peak intensities to obtain a difference. The present invention can calibrate the ultrasonic scanner according to the difference, which can not only omit the existing calibration method of using a water tank or an additional ultrasonic target, but also avoid calibration errors caused by parallax.

Description

[0001] priority claim [0002] This patent application claims priority to US Application Serial No. 61 / 936,232, filed February 5, 2014, which is incorporated herein by reference. technical field [0003] The present invention relates to a method of calibrating an ultrasonic scanner, and in particular to a method of calibrating an ultrasonic scanner with a transducer. Background technique [0004] Existing ultrasonic scanners with transducers can be used to measure bladder volume. However, due to errors in calibration before measurement, the measured bladder volume is quite different from the actual situation. [0005] The existing calibration method uses a spiral ultrasonic target to be placed in a water tank for manual calibration, and after the calibration is completed, the water in the water tank is emptied for subsequent measurement, which is very time-consuming and labor-intensive. Furthermore, the calibration process assumes that the center of the dome is perfectly a...
