ULTRASONIC DIAGNOSIS DEVICE AND METHOD FOR DETECTING ROTATION ANGLE OF ULTRASONIC PROBE AND METHOD FOR DISPLAYING ULTRASONIC DIAGNOSIS IMAGE

摘要

PURPOSE: To automatically rotate the display picture according to the rotation of the ultrasonic probe. ;CONSTITUTION: Two accerelation sensors 2a and 2b which detect the accerelation of directions (a) and (b) which cross in parallel to the scanning surface (g) of an ultrasonic probe 1 and at right angles with the center axis (e) of a scanning surface (g) are separated by a specific distance in the direction of the center axis (e) of the scanning surface (g). They are integrated on an ultrasonic probe 1. ACPU 12 detects the rotation angle θ of the ultrasonic probe 1 based on the intensity of accerelations A and B which ate detected by the accerelation sensors 2a and 2b and th difference of codes. A DSC5 provided with display picture rotating function rotates the display image on the CRT 7. Thus, when rotating the ultrasonic probe, the display picture is rotated and the organic image is not rotated so that the organs and its location can be easily recognized.;COPYRIGHT: (C)1995,JPO
