あるという問題もある。(Prior Art) Conventionally, there is a mechanical sector type transvaginal probe shown in FIG. 6 that is inserted into a subject, for example, the vagina of a human body, for the purpose of diagnosing uterine diseases. In other words, the conventional transvaginal probe 1 shown in FIG. It consists of a grip part 3 connected to the base end of the grip part 3. This transvaginal probe II emits an ultrasound beam while mechanically rotating a small transducer 4 attached to a transducer rotating section 2. Therefore, in this transvaginal probe 11, the small vibrator 4 can be rotated at a rotation angle of, for example, 2.
Since the ultrasonic beam can be emitted over 40 degrees, a wide-angle cross-sectional image of the living body corresponding to the ultrasonic image plane indicated by diagonal lines can be obtained. However, this transvaginal probe 11
Since this method uses mechanical scanning, there are many artifacts due to multiple window materials, etc., and since the shaft is fixed and the insertion part l lacks flexibility, it is difficult to obtain a cross-sectional image of the body at a different angle from the axial plane. Therefore, there is a problem in that it is not necessarily possible to flexibly select cross-sectional images that are easy to understand in terms of resolution. In addition, this transvaginal tube 1 and lobe 11 have the problem that polarization is difficult due to their structure.
