Human body part detection and identification system and method for diagnosis and treatment equipment

The invention relates to an X-ray beam control system for a diagnosis and treatment device, in particular to a body part detection and recognition system and method combined with a depth camera.

Today's medical routine inspections often use X-ray equipment. The X-ray imaging device mainly includes an X-ray source generator, a collimator, and an X-ray sensor. The X-ray sensor is disposed under a target human body at a predetermined distance from the X-ray source generator. The X-ray beam emitted by the X-ray source generator is projected by the X-ray source through an X-ray source to a target human body, and is sensed by the X-ray sensor.

In the traditional medical treatment process, due to the large number of daily consultations and the cumbersome medical procedures, the medical staff may give a situation of transmitting errors when the X-ray command is given to the radiologist, and because of the personal experience of the radiologist. Factors such as professionalism, work mood, temporary negligence, misunderstanding and other factors cannot correctly understand the patient's irradiated parts, so that the X-ray photographs presented by the doctors are returned to the hands of medical staff, and the patients who are not required by the medical staff are correct. X-ray photo.

The use of non-patient correct X-rays by medical staff may lead to misjudgment or diagnosis errors, and may even require patients to perform X-rays repeatedly. In this way, in addition to increasing the number of exposures of the human body to the X-ray beam, it is more likely that the human body will absorb excessive X-ray radiation values. In traditional X-ray equipment, it is impossible to judge that the patient is an adult or a young child. The X-ray radiation dose is designed to be used in adults. It is also possible to expose the X-ray radiation value of a child to a child. Young children are overabsorbed.

The technical means for achieving the above object is to combine a depth camera and an image signal recognition device in a human body part detection and identification device, wherein the image signal recognition device obtains an instantaneous image pixel depth according to the depth camera. The signal is compared with an image pixel depth signal of a predetermined body part pre-stored in a human body part image data storage device.

When the image signal recognition device does not match the image pixel depth signal of the predetermined body part, the human body identification error signal is generated; and when the comparison is recognized, a human body identification is generated correctly. signal.

The processing unit can determine whether the X-ray generator can be triggered to generate an X-ray beam to be selected to the selected part of the human body according to the human body identification error signal and the human body identification correct signal.

The body part error detection device may include an image capturing device.

The human body part error detection device may include a display device connected to the processing unit for displaying an instant image pixel depth signal captured by the depth camera and an image captured by an image capturing device.
