Abstract

This disclosure describes a system, a method, and a computer program that enable calculation of prevalence of repeated medical imaging at a medical facility. In one embodiment, a computer receives packets transmitted over a communication network, where the packets include data related to operation of one or more medical imaging devices at the medical facility. The computer performs deep packet inspection (DPI) of the packets, and extracts, from results of the DPI, values indicative of medical images acquired using the one or more medical imaging devices. The computer identifies, based on the values, instances of repeated images, where a repeated image involves acquiring images of the same patient and body part multiple times, utilizing a certain type of medical imaging device within a predetermined period. The computer calculates, based on the instances, a value indicative of the prevalence of repeated medical imaging at the medical facility.

Claims

1. A system configured to calculate prevalence of repeated medical imaging, comprising:

a computer configured to;

receive packets transmitted over a communication network, wherein the packets comprise data related to operation of one or more medical imaging devices at a medical facility;

perform deep packet inspection (DPI) of the packets;

extract, from results of the DPI, values indicative of medical images acquired using the one or more medical imaging devices;

identify, based on the values, instances of repeated images;

wherein a repeated image involves acquiring images of the same patient and body part multiple times, utilizing a certain type of medical imaging device within a predetermined period; and

calculate, based on the instances, a value indicative of the prevalence of repeated medical imaging at the medical facility.

2. The system of claim 1, wherein the communication network comprises a networking device that has a mirror port that is configured to duplicate the packets, which are transmitted over the communication network;

and wherein the computer is connected to the mirror port and is configured to receive the packets via the mirror port.

3. The system of claim 1, wherein at least some of the values identify one or more of the following:

patients being imaged, types of images being acquired, and body parts being imaged.

4. The system of claim 1, wherein at least some of the repeated images are not stored in a Picture Archiving and Communication System (PACS) server of the medical facility.

5. The system of claim 1, wherein at least some of the repeated images were deleted from a PACS server of the medical facility.

6. The system of claim 1, wherein the computer is further configured to alert about excessive repeated medical imaging responsive to the prevalence reaching a predetermined threshold;

and wherein the predetermined threshold is calculated based on results of DPI of other packets transmitted over one or more communication networks.

7. The system of claim 1, wherein the computer is further configured to identify, based on the results of the DPI of the packets, additional values identifying technicians who acquired medical images, and to calculate values indicative of prevalence of repeated medical imaging by each of the technicians.

8. The system of claim 7, wherein the computer is further configured to alert about excessive repeated medical imaging by a certain technician responsive to prevalence of repeated medical imaging by the certain technician reaching a predetermined threshold.

9. The system of claim 1, wherein the computer is further configured to identify, based on the results of the DPI of the packets, additional values identifying body parts that were imaged, and to calculate values indicative of prevalence of repeated medical imaging of different body parts.

10. The system of claim 1, wherein the computer is further configured to identify, based on the results of the DPI of the packets, additional values that identify models of medical imaging devices that were utilized, and to calculate values indicative of prevalence of repeated medical imaging when utilizing different models of medical imaging devices.

11. The system of claim 1, wherein the computer is further configured to receive additional packets transmitted over communication networks of multiple medical facilities, wherein the additional packets comprise data related to operation of additional medical imaging devices at the multiple facilities;

perform DPI of the additional packets;

extract, from results of the DPI of the additional packets, additional values indicative of medical images acquired using the additional medical imaging devices;

identify, based on the additional values, additional instances of repeated medical imaging;

calculate, based on the additional instances, values indicative of the prevalence of repeated medical imaging at the multiple medical facilities; and

report a comparison between the prevalence of repeated medical imaging at the medical facility and the prevalence of repeated medical imaging at the multiple medical facilities.

12. The system of claim 1, wherein the packets are not transmitted in response to a query of the computer to a PACS server.

13. A method for calculating prevalence of repeated medical imaging, comprising:

capturing packets transmitted over a communication network, wherein the packets comprise data related to operation of one or more medical imaging devices at a medical facility;

performing deep packet inspection (DPI) of the packets;

extracting, from results of the DPI, values indicative of medical images acquired using the one or more medical imaging devices;

identifying, based on the values, instances of repeated images;

wherein a repeated image involves acquiring images of the same patient and body part multiple times, utilizing a certain type of medical imaging device within a predetermined period; and

14. The method of claim 13, further comprising alerting about excessive repeated medical imaging responsive to the prevalence reaching a predetermined threshold;

wherein the predetermined threshold is calculated based on results of DPI of other packets transmitted over one or more communication networks of one or more medical facilities.

15. The method of claim 13, further comprising capturing additional packets transmitted over communication networks of multiple medical facilities, wherein the additional packets comprise data related to operation of additional medical imaging devices at the multiple facilities;

performing DPI of the additional packets;

extracting, from results of the DPI of the additional packets, additional values indicative of medical images acquired using the additional medical imaging devices;

identifying, based on the additional values, additional instances of repeated medical imaging;

calculating, based on the additional instances, values indicative of the prevalence of repeated medical imaging at the multiple medical facilities; and

reporting a comparison between the prevalence of repeated medical imaging at the medical facility and the prevalence of repeated medical imaging at the multiple medical facilities.

16. The method of claim 13, further comprising:
