APPLICATOR FOR UTERINE CANCER INTRACAVITARY IRRADIATION, RADIATION TREATMENT PLANNING METHOD OF UTERINE CANCER AND RADIATION TREATMENT PLANNING DEVICE OF UTERINE CANCER

摘要

PROBLEM TO BE SOLVED: To provide an applicator for uterine cancer intracavitary irradiation in which a three-dimensional ultrasound image of less noise and high resolution can be obtained while being low cost and simple in comparison with CT and MRI, the resolution of soft tissue is high in comparison with the CT, time and labor are not taken in imaging in comparison with the MRI, there is no need to move a patient to an examination room for imaging like the CT and the MRI, and therefore the slippage or detachment of an intracavitary irradiation applicator is never caused, and it is highly accurate and safe, and provide a radiation treatment planning method of the uterine cancer and a radiation treatment planning device of the uterine cancer.;SOLUTION: An applicator 21 for uterine cancer intracavitary irradiation is provided which is used for intracavitary irradiation of the uterine cancer and has an ultrasonic probe 41 for transmitting and receiving ultrasonic wave. The applicator has the uterine radiation irradiation uterine applicator and a vagina radiation irradiation vagina applicator, and preferably, the uterine applicator may be an embodiment having a probe 40 with the ultrasonic probe being built therein, and the probe with the ultrasonic probe may be the embodiment being rotatable and being movable in an axial direction.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
