Embodiment 1

[0014] Such as figure 1 As shown, first on the treatment bed base plate 4, a hole whose shape and size match the outer contour of the upper part of the cover 1 is opened, and a shape-fixed cover 1 is embedded in the hole, such as a cover 1 made of plexiglass. Before starting the treatment, an appropriate amount of tissue equivalent liquid such as water 3 is injected into the cover 1 . The patient is then placed prone on the treatment couch floor 4 with her breasts placed in said hood. A 3D ultrasound probe 2 with a known position is detachably connected under the cover 1, and the 3D ultrasound probe 2 is used to scan the breast, obtain an anatomical image of the breast, and then calculate the coordinate position of the lesion. Since the patient is on the treatment bed floor 4 of the treatment machine at this time, the converted lesion coordinates are the positions where the rays should be irradiated, thereby completely avoiding setup errors. At the same time, since the shape...

Embodiment 2

[0016] One of the differences between this embodiment and Embodiment 1 is that the imaging device uses a conventional ultrasonic probe installed on a driving device with a three-dimensional model reconstruction software module instead of the 3D ultrasonic probe. Specifically, the driving device with the three-dimensional model reconstruction software module is a mechanical device that can drive the probe to rotate or swing to scan, and it scans the breast through the drive of the automatic control system to obtain a series of ultrasound images with known orientations, and then through Computer software reconstructs the three-dimensional model of the breast to determine the coordinates of the lesion location. Another difference between it and Embodiment 1 is: there is also anti-slip material (not shown in the figure) around the opening to prevent the lesion from shifting due to sliding when the patient lies prone on the treatment bed.

Abstract

The invention discloses a galactophore positioning device, which comprises a cover with a stationary shape, and further comprises an imaging device which is detachably and flexibly connected with the cover. The coordinate position of the imaging device is known, and the imaging device is used for scanning galactophore, obtaining anatomic images and calculating corresponding coordinate positions. The galactophore positioning device can greatly increase repetitive positioning accuracy and obtain the exact repetitive positioning error; and proper quantities of tissue equivalent liquid can be also injected into the cover to obtain a continuous medium required by imaging, thereby facilitating the calculation of the radiation exposure dose.

Description

technical field [0001] The invention relates to a positioning device, in particular to an image-guided mammary gland positioning device. Background technique [0002] Breast cancer is a malignant tumor arising from the ductal epithelium of the mammary gland, and is a common malignant tumor in women. According to authoritative medical statistics, every 13 minutes in the world, one person dies of breast cancer. Breast cancer has become an important disease that seriously threatens women's health. As the incidence increased, the mortality rate also increased significantly. [0003] Radiation therapy for tumors is the treatment of tumors with high-energy rays. Specific to breast cancer radiotherapy, it is one of the three major treatment methods for breast cancer, namely surgery, chemotherapy and radiotherapy. Radiotherapy plays an important role in the treatment of breast cancer. [0004] In the "Breast Cancer Clinical Practice Guidelines" formulated by the non-profit academ...
