All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic structural diagram of a radiotherapy patient safety monitoring and management system according to an embodiment of the present invention, which is used for monitoring a patient on a treatment table and is connected to an accelerator. The system comprises: the imaging device 1 is used for acquiring a body surface image of a patient. The body surface image comprises current mark points for marking the target area position of the patient. And the upper computer 2 is connected with the camera device 1 and the accelerator.
In this embodiment, because the patient is when preparing to treat, corresponding mark object has been placed in the body surface department that corresponds target area position, like pellet etc. camera device 1 is through obtaining patient's body surface image this moment to obtain the body surface image that has the mark object, the image of mark object is current mark point promptly in the body surface image this moment. Preferably, the imaging device 1 employs a 3D optical camera.
As shown in fig. 2, the upper computer 2 includes an identification unit 11 for identifying whether a coordinate difference between the current mark point and the historical mark point is within a preset range. And the matching unit 12 is configured to acquire the identity information of the patient when the coordinate difference is outside the preset range, and match the identity information with preset treatment plan information. And the adjusting unit 13 is used for adjusting the position of the accelerator according to the coordinate difference when the matching is successful, so that the accelerator acts on the target area position during operation. And a prompt unit 14 for generating first prompt information when the identity information fails to match the treatment plan information.
In this embodiment, the historical mark points are coordinate positions where the object is located when the patient is treated last time. Because human size change, like fat thin change, can lead to the mark point of pasting in same position that camera device 1 monitored to carry out the coordinate position when treating at last patient, different with the coordinate position when the time patient carries out the treatment, the target area position that historical mark point was fixed a position this moment can the deviation appear, the wrong condition of target area position location appears. Therefore, when the recognition unit 11 recognizes that the coordinate difference between the current marking point and the historical marking point is within the preset range, it indicates that the body size of the patient does not change or the change does not affect the positioning of the target area, and the accelerator is turned on for radiotherapy.
When the coordinate difference between the current marking point and the historical marking point is larger than the preset range, the matching unit 12 is used for determining whether the identity information of the patient currently undergoing treatment is consistent with the currently called treatment plan information, wherein the treatment plan information comprises the personal identity information, the medical record information, the preset treatment duration information and the like of the patient. When the matching unit 12 successfully matches the identity information with the treatment plan information, it indicates that the patient is correctly identified, and the adjusting unit 13 adjusts the position of the accelerator according to the coordinate difference between the current mark point and the historical mark point, so that the beam-emitting direction of the accelerator is over against the target position corresponding to the current mark point when the accelerator is in operation, and the treatment is more accurate.
When the matching unit 12 fails to match the identification information with the treatment plan information, indicating that the patient identification is wrong, a first prompt message is generated by the prompt unit 14 to prompt an external patient identification mistake. The first prompt message can be any one or more of sound and light alarm messages.
