Background technique

At present, breast disease is the most common disease among women, and the death rate of breast cancer ranks second among female tumors. Early detection of breast cancer is an effective means to improve its cure rate. In order to reduce the diagnosis of breast biopsy, a large number of non-destructive diagnostic methods for breast diseases have been produced, mainly including: mammography mammography, ultrasound mammography, magnetic resonance (MRI) breast examination and other functional imaging methods.

In the breast CT process, due to the unreasonable design of the detection bed body, other parts of the patient's body are also exposed to X-ray irradiation for a long time, resulting in excessive radiation and serious consequences, and the structure of the detection bed in the prior art It is also not conducive to determining the position of the lesion in the human body.

The purpose of the utility model is to provide a detection bed for breast CT detection, which can accurately locate the space of the breast part of the human body to be detected, and minimize the X-ray irradiation dose received by other parts of the human body.

The purpose of this utility model is achieved through the following technical solutions, a detection bed for breast CT detection, the detection bed has a special frame structure bed, the bed is covered with a lead layer around the bed, only on the human body to be tested There are detection holes in the place where the mammary gland is placed;

A low-density guiding device, a CT optical machine front collimator, a CT optical machine and a detector are installed in the detection hole, and the above components are all installed in a protective lead layer.

A video positioning system is also installed in the detection hole.

The testing bed also includes an upper bed board supporting the weight of the human body to be tested, the upper bed board is connected with the bed body of frame structure, and the outer shell part of the testing bed wraps and protects the whole testing bed body.

It can be seen from the above-mentioned technical solution provided by the utility model that the detection bed has a special frame-type bed body, and the periphery of the bed body is covered with a lead layer, and only a detection hole is opened at the place where the human mammary gland is placed; A low-density guiding device, a front collimator of a CT light machine, a CT light machine and a detector are installed in the hole, and the above-mentioned components are all installed in a protective lead layer. The detection bed can accurately locate the spatial location of the breast part of the human body to be detected, and minimize the X-ray irradiation dose received by other parts of the human body.

Description of drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings that need to be used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention , for those skilled in the art, other drawings can also be obtained based on these drawings without creative work.

Fig. 1 is a schematic structural diagram of a detection bed for breast CT detection provided by an embodiment of the present invention.

Detailed ways

The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. . Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

The embodiment of the utility model will be further described in detail below in conjunction with the accompanying drawings. As shown in FIG. Including detection hole 1, low-density guiding device 2, CT optical machine front collimator 3, CT optical machine 4, detector 5, video positioning system 6, protective lead layer 7, upper bed board 8, frame structure bed body 9, and shell 10, where:

The detection bed has a special frame structure bed body 9, and the periphery of the bed body is covered with a lead layer, and only a detection hole 1 is opened at the place where the human mammary gland is placed to protect other parts of the human body from being irradiated by X-rays during the detection process. ;

A low-density guiding device 2 , a CT optical machine front collimator 3 , a CT optical machine 4 and a detector 5 are installed in the detection hole, and the above components are all installed in a protective lead layer 7 . Wherein, the low-density guiding device 2 is used for guiding and locating the measured human breast tissue without affecting the detection.

In specific implementation, a video positioning system 6 is also installed in the detection hole 1, which can provide the operator with the positioning information of the measured human breast tissue, and can be controlled by the operator to perform micro-positioning adjustment when necessary.

And through the above-mentioned CT optical machine front collimator 3, low-density guiding device 2 and video positioning system 6, it can ensure that the dose of X-ray irradiation received by the chest cavity of the human body close to the breast tissue is minimized.

The above testing bed further includes an upper bed board 8 supporting the weight of the human body to be tested. The upper bed board 8 is connected to the frame structure bed body 9, and the outer shell 10 of the testing bed wraps and protects the whole testing bed body.

The working process of the above-mentioned examination table will be described in detail with specific examples, taking Figure 1 as an example:

In the detection process of the human mammary gland portion using the detection bed described in this embodiment, X-rays are emitted from the CT optical machine 4, and are limited by the structure of the front collimator 3 of the CT optical machine processed by high-density materials, so that the X-rays It can only be irradiated within the range of detector 5. The human body to be tested lies prone on the upper bed board 8, and its breast tissue enters the detection area equipped with the protective lead layer 7 from the detection hole 1 and the low-density guide device 2 installed on the hole; the middle part of the low-density guide device 2 has a round hole , the opening size and sag angle have been reasonably calculated and optimized to ensure accurate positioning and guidance of human breast tissue, and to prevent other non-detection parts of the human body from entering the detection area and being exposed to X-rays.

The operator can locate the measured human breast tissue through the video positioning system 6 installed inside the device, and can be precisely and adjusted by the operator's operation and control when necessary.

To sum up, the detection bed of this embodiment can achieve accurate spatial positioning of the breast part of the human body to be detected through structural design and material selection, and minimize the X-ray irradiation dose received by other parts of the human body.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any person familiar with the technical field can easily think of All changes or replacements should fall within the protection scope of the present utility model.
