Real-Time Automatic Scheduling and Control System for Positron Emission Tomography Patients Based on Bluetooth Beacon Positioning

The PET scan is one of the commonly used inspection items today. There are many pre-operations to be performed in the inspection process, and there are different medicament cycle times for different inspection sites. At present, medical personnel use manual methods to calculate the estimated shadow time of each device. However, the number of imaging equipment is extremely small, the number of patients is very large, and the reserved patients and temporary patients arrive at the scene at different times, and there are different examination items, bed and medication waiting time calculations, imaging failures and imaging again ... Manual scheduling is extremely complex. Coupled with this changing schedule, it is difficult to announce the estimated time to patients and their families in real time, resulting in family members constantly asking the medical staff about the waiting time and other conditions, which not only consumes the physical and mental strength of the medical staff, but also causes the process to be smooth. Previous research has proposed algorithms for specific inspections to solve the problem of equipment resource allocation, and also calculated outpatient visits for outpatient clinics. However, there is no research aimed at improving the process of positivity.This project proposes a real-time automatic scheduling and control system for PET patients based on Bluetooth Beacon positioning. This system can automatically schedule, estimate, and update the start and end time of various tasks of PET patients in real time. Allocate beds and announce schedule information in real time to automate, optimize and optimize the schedule. This can greatly reduce the work of medical staff, avoid human error, and provide medical staff, patients and family members to view the inspection progress and estimated waiting time in real time, reducing the number of patients and family members to ask medical staff. We expect to implement this system on Android phones to prove the feasibility of the system. We plan to first collect time data of 200 actual patients in the Nuclear Medicine Department of Chang Gung Hospital, Linkou, and put the collected data into another implemented simulation program. The preliminary simulation results on the computer found that the average time difference between manual scheduling and automatic scheduling was 5.17 minutes, and the total examination time of 54% of patients could be reduced by 4 minutes on average. As far as we know, this project is the first to propose a real-time automatic scheduling and control system for PET patients.
