In this application, the specific location may be the patient's larynx.

Swallowing is an important physiological function of the human body. Swallowing can be physiologically divided into three phases, the oral, pharyngeal and esophageal phases. When swallowed, movement of the thyroid cartilage causes changes in the surface of the laryngeal skin, and changes in the position of the laryngeal process reflect movement of the thyroid cartilage. Since cartilage and muscle in the pharyngeal stage move strongly, the movement of the throat is often considered an indicator of swallowing. The movement of the thyroid cartilage in the larynx is readily observed on the body surface, and thus, the swallowing function of a patient can be analyzed by detecting the movement of the larynx of the patient.

In the world of world new crown abuse and normalization, various physiological indexes of new crown positive patients and people after new crowns are cured, particularly related respiratory tract related researches show that if the patients obtain new crown virus infection, discomfort of throat, pharyngalgia, cough, dyspnea and other uncomfortable symptoms, the swallowing movement frequency and amplitude of the throat can be changed in different degrees, and even if the new crowns are cured, the movement indexes of related organs can still be influenced due to irreversible functional damage caused by throat mucous membrane damage.

According to the patient specific position image acquisition device, the laryngeal movement indexes of the patient with the new crown and the patient with the new crown cured can be acquired, and research conditions are provided for complications, prognosis and related mechanisms of the new crown.

Embodiment IV

Tumor radiotherapy is a local treatment for tumors using radiation. The radioactive rays used include alpha, beta and gamma rays generated by radioactive isotopes, and x rays, electron beams, proton beams and other particle beams generated by various x-ray therapeutic machines or accelerators. About 70% of cancer patients require radiation therapy in the course of cancer treatment, and about 40% of cancers can be cured by radiation therapy. The role and position of radiotherapy in tumor treatment are increasingly prominent, and the radiotherapy has become one of the main means for treating malignant tumors.

In the prior art, treatment is usually performed using a large radiotherapy accelerator. These devices are typically purchased by a hospital and distributed within the treatment room of a radiation treatment department. Because of the enormous capital costs and importation of such equipment, it is difficult for hospitals, or even physicians in the hospitals, to request the equipment manufacturers to make customized changes to the equipment. And the inventory equipment that has been purchased is not readily replaceable and modifiable.

The main body of the radiation therapy accelerator in the prior art often comprises two parts, namely a radiation generating device 1 and a medical bed 2. Referring to FIG. 1, a typical prior art radiation therapy accelerator is illustrated. This radiotherapy accelerator includes: the radiation therapy apparatus comprises a radiation generating device 1 and a medical bed 2, wherein the radiation generating device 1 comprises an accelerator frame 12 and a control cabinet 11, and the accelerator frame 12 can rotate 360 degrees relative to the medical bed 2, so that an accelerator head on the accelerator frame 12 can irradiate an affected part of a patient from a required angle. The medical bed 2 is used for the patient to lie down, and the affected part of the patient can be placed in the irradiation area of the radiation generating device 1 by adjusting the height and position of the bed.

It follows that the prior art radiotherapy accelerators are self-consistent, complete products and are expensive. For hospitals, procurement of such radiotherapy accelerators is often long periodic, not updated at will, and unlikely to destructively retrofit existing equipment. As such, when the doctor needs to further collect some data of the patient during radiotherapy or to complete some functions of radiotherapy treatment, it is difficult to conveniently attach the auxiliary device 4 to the self-consistent device.

In view of the above, the embodiments of the present application provide an image capturing apparatus for a patient-specific region, which is convenient for application to a large-scale radiation therapy accelerator.

The apparatus for acquiring an image of a specific region of a patient according to the present embodiment is shown in fig. 9 and 10, and includes an auxiliary device 4 and a support for an auxiliary device of a medical couch according to the first embodiment, the specific region is a larynx of the patient, the medical couch 2 is a radiotherapy couch, the auxiliary device 4 is a camera, and the auxiliary device 4 is used for acquiring a moving image of the larynx of the patient during radiotherapy.

In the chinese utility model patent application No. CN202120358701.8, a support for auxiliary equipment of a hospital bed is provided at a position close to the head of a patient. The range of motion of the accelerator housing 12 at the top of the patient's head has to be taken into account when using the hospital bed accessory support on a radiotherapy bed. It is difficult for the bracket to have a sufficient height. This is not a problem in the process for monitoring the patient's eye movements, but is difficult to achieve when monitoring the patient's laryngeal movements due to occlusion by the patient's head, particularly the chin.

In addition, when monitoring the laryngeal movement of the patient, the monitoring effect is best when the laryngeal movement of the patient is directly opposite to the laryngeal position of the patient, so that the higher the height of the first cross beam 35 is, the better the monitoring effect is. Referring to fig. 9, when the first cross member 35 of the support for the auxiliary equipment of the medical bed is raised to the highest position, the best image can be obtained.

However, when the accelerator housing 12 is rotated so that the exit of the radiation is positioned above the head of the patient, the image acquisition of the auxiliary equipment 4 will be obstructed. Therefore, optionally, the patient-specific part image acquisition apparatus further comprises: and a position sensor 5 which is connected with the driving device in a communication way, wherein the position sensor 5 is used for detecting the height of the radiation generating device 1 of the radiotherapy accelerator. Referring to fig. 10, when the driving device detects that the height of the radiation generating device 1 is higher than the preset height, the telescopic rod 382 is driven to lower the camera.

That is, when the height of the radiation generating apparatus 1 is higher than the preset height, it may still be ensured that a relatively low-quality image can be obtained by automatically lowering the camera, avoiding interruption of image acquisition.

The position sensor 5 may be a sensor built into the radiation generating device 1, i.e. the drive device may be controlled by acquiring position data from the position sensor 5 carried by the radiation generating device 1. However, the radiation generating device 1 of the prior art may not open its position data interface, so as shown in fig. 9 and 10, the position sensor 5 may be externally disposed on the accelerator frame 12, and the position sensor 5 may be based on laser ranging or air pressure, accelerometer, etc. Through external position sensor 5, need not carry out destructive transformation to the radiotherapy accelerator, realized the automatic rising of first crossbeam 35 under low cost.

In addition, it is worth mentioning that the new corona virus is mainly transmitted through the respiratory tract, the radiotherapy room is a closed space, and the mask of the patient needs to be removed during radiotherapy, so that the respiratory infection probability of the contact person can be increased by the radiotherapy of the new corona patient. The application provides a specific position image acquisition device of patient based on vision to patient's larynx swallowing motion real-time supervision, and non-contact can be in radiotherapy room's external control and acquisition data, has avoided closely contacting, has reduced the probability of respiratory infection.

Finally, it should be noted that those skilled in the art will appreciate that embodiments of the present application present many technical details for the purpose of enabling the reader to better understand the present application. However, the technical solutions claimed in the claims of the present application can be basically implemented without these technical details and various changes and modifications based on the above-described embodiments. Accordingly, in actual practice, various changes in form and detail may be made to the above-described embodiments without departing from the spirit and scope of the present application.
