[0002] Medical imaging technology has become a key component of the modern medical system. These technologies can not only provide accurate disease diagnosis, but also play an irreplaceable role in early lesion detection, treatment plan formulation and efficacy evaluation. Therefore, improving the efficiency of appointments for these examinations can not only greatly optimize the allocation of medical resources and reduce the idle time of medical equipment, but also significantly improve patient experience, shorten the treatment cycle and speed up recovery.

[0003] In the actual medical appointment system process, the appointment efficiency is low, which will lead to uneven resource allocation and appointment time conflicts. And when patients and doctors have difficulty obtaining real-time equipment status information, it will lead to inaccurate or delayed appointment decisions, greatly affecting the efficiency of diagnosis and treatment.

[0004] Medical imaging equipment such as CT scans and X-ray examinations involve ionizing radiation, and proper management is crucial for patient safety. However, the existing manual appointment system fails to effectively implement radiation dose monitoring and early warning mechanisms, which may increase patients' long-term radiation risks. Such technical and operational limitations may not only endanger patient safety, but also limit the transparency and efficiency of medical services.

[0005] Therefore, how to effectively improve the efficiency of medical resource allocation through automation and intelligent means, and monitor radiation dose to ensure the safety of the medical process has become an urgent problem to be solved. Summary of the invention

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention and implement it, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the scope of protection of the present invention.

[0036] Example

[0037] The present invention provides an intelligent reservation method for the imaging department, such as Figure 1 As shown, the specific steps include:

[0038] S1. Obtain the initial appointment schedule and patient information; the patient information specifically includes the patient's personal information, radiation dose information and examination item data. Specifically, the appointment schedule and patient information to be filled in are obtained from the hospital system.

[0039] S2. Data preprocessing, updating the initial appointment schedule, including deleting the expired time and its appointment schedule, and adding the newly opened appointment time on the 30th day from the current day.

[0040] Import patient information and examination item data into the rule base, and use four eigenvalues ​​to form a 1×4 matrix to represent the key points of different examinations under different rule requirements, and output eigenvalues ​​to describe the key features of the examination items. This includes importing the patient's physical data and examination data, and representing the type of examination item as a one-dimensional matrix according to the rule base, and using a matrix composed of multiple eigenvalues ​​to describe the key points of different examinations under different rule requirements.

[0041] S3. Input the patient's personal information, feature values ​​and updated time information into the scoring function, and perform a multi-dimensional comprehensive scoring of the patient information and examination items according to the imaging department's examination rule library. Specifically, the following steps are included:

[0042] S31: extracting time information from the updated appointment schedule, including the date of the available appointment, the specific time period and the corresponding imaging examination equipment.

[0043] S32: The imaging examination rule base specifically includes sequence rules, exclusion rules and hospital management rules. The key points of the sequence rules include: considering the age of the patient, giving priority to young and elderly patients; considering whether the patient needs to be fasting, the examination that requires fasting should be arranged in the morning time period; considering whether the patient is an emergency patient, emergency patients should be given priority; the key points of the hospital management rules include: for some enhanced examinations (such as enhanced CT and vascular examinations, etc.), specific examination equipment should be given priority; the key points of the exclusion rules include: avoiding conflicts in some examinations, such as the time interval between abdominal enhanced CT and vascular examinations of more than 24 hours. Due to different examination types, the specific content of the above examination rules will vary, but the rule base framework can be adjusted according to the specific content of various imaging examination rules.

[0044] According to the radiology examination rule library, multi-dimensional comprehensive scores are given to patients and their related examination items, the importance of each rule is evaluated and the scoring function parameters are adjusted.

[0045] S33: Based on the preprocessed information, the score of the examination item for a certain rule is obtained through the scoring function. When the rule is met, a lower score (negative number) is awarded; when the rule is not met, a higher score (positive number) is awarded. The rules of the scoring function are set according to the examination rule library of the imaging department. The scoring function and parameters are different for different examination items. For example, in MRI and CT systems, because the rule library is not completely consistent, there are differences in the scoring function, and the scoring function can adjust the parameters according to the specific situation.

[0046] S4. Compare the total score of the examination items to be scheduled for the current patient with the feasible threshold for rationality check; if the total score of the current patient is reasonable, compare it with the total score of the existing alternative patients. For each available appointment time period, all examination items of all patients to be scheduled are traversed, and the total score of all patients to be scheduled are sorted in descending order. According to the sorting result, a preliminary updated appointment schedule is output.

[0047] S5. Calculate the patient's imaging examinations within one year based on the patient's radiation dose information to obtain the cumulative total radiation dose, such as X-ray examinations and CT examinations. The specific calculation method is to count the cumulative radiation doses of all X-ray examinations, CT examinations and other imaging examinations with ionizing radiation that the patient has undergone within one year. MRI examinations are not included in the calculation range.

[0048] Set a safe radiation dose threshold. When a patient with a risk of exceeding the radiation dose limit is initially updated in the appointment schedule, the patient's appointment information is screened out, the screened appointment schedule is output, and an early warning message is sent to the doctor, technician, and patient. The radiation dose warning is performed after it is determined that a certain examination of the patient has been scheduled.

[0049] like Figure 3 and Figure 4 , the present invention uses 1000 simulation data as an example, performs intelligent system appointment and manual appointment respectively, and counts the total time consumption and rule compliance rate. The total appointment time consumption of the present invention is much less than that of manual appointment, and in terms of rule compliance rate, it is better than manual sorting, especially exclusion rules (all data p<0.05). It also provides a radiation dose warning function, which can effectively evaluate and prompt radiation risks, and further optimize inspection arrangements.

[0050] The present invention also provides an intelligent appointment system for the imaging department. Figure 2 As shown, specifically including:

[0051] The information docking module is used to obtain the initial appointment schedule and patient information; patient information specifically includes patient personal information, radiation dose information and examination item data.

[0052] The preprocessing module is used to update the initial appointment schedule; import the patient's personal information and examination item data into the rule base, and output feature values, which are used to describe the key characteristics of the examination items.

[0053] The multi-dimensional evaluation module is used to input the patient's personal information, characteristic values ​​and updated schedule into the scoring function, conduct a multi-dimensional comprehensive scoring of the patient information and its examination items, and output the total score of the examination items to be scheduled; traverse all patients to be scheduled and their examination items, sort the total score of all patients to be scheduled from large to small, and output a preliminary updated appointment schedule based on the sorting results.

[0054] The radiation dose warning module is used to calculate the total radiation dose based on the patient's radiation dose information and set a safe radiation dose threshold. When a patient with a risk of exceeding the radiation dose standard is initially updated in the appointment schedule, the patient's appointment information will be screened out, the screened appointment schedule will be output, and a warning message will be sent to the patient and physician ends.
