Abstract

A method of searching video content for specific subject matter of interest augments traditional image data analysis methods with analysis of contemporaneously gathered non-image data. One application involves video recordings of medical procedures performed using a medical device. When a user desires to locate portions of video recordings showing a medical event of interest, one or more medical device system events likely to correspond to the occurrence of the medical event of interest are identified from one or more procedure event logs. Timestamps associated with these system events are used to identify candidate video clips from the procedure video recordings. Image data analysis is performed on the candidate video clips to determine whether each candidate video clip contains the medical event of interest.

Claims24

Dependent claims

A method comprising:

receiving a user command to locate one or more video clips showing a medical procedure event of interest, that is a portion of a medical procedure performed on a medical system, from one or more medical procedure video recordings of the medical procedure:
identifying, from one or more medical system event logs that record the occurrence of medical system events, during performance of the medical procedure on the medical system, and the time of occurrence of medical system events on the medical system, one or more medical system events occurring on the medical system during the medical procedure likely to correspond to the occurrence of the medical procedure event of interest;
identifying one or more candidate video clips from the one or more medical procedure video recordings, using one or more timestamps corresponding to each of the one or more identified medical system events occurring on the medical system;
determining, by analyzing the image data of the one or more candidate video clips, whether each of the one or more candidate video segments is an identified video segment that contains the medical procedure event of interest;
and
presenting to a user at least one identified video segment.

3 more elements

A device for performing a video search, comprising:

a user interface;
and
a processing unit operatively coupled to the user interface, the processing unit including one or more processors, wherein the processing unit is configured to:
receiving, via the user interface, a user command to locate one or more video clips showing a medical procedure event of interest, that is a portion of a medical procedure performed on a medical system, from one or more medical procedure video recordings of the medical procedure;
identifying, from one or more medical system event logs, that record the occurrence of medical system events. during performance of the medical procedure on the medical system,. and the time of occurrence of medical system events on the medical system, one or more medical system events occurring on the medical system during the medical procedure likely to correspond to the occurrence of the medical procedure event of interest;
identifying one or more candidate video clips from the one or more medical procedure video recordings, using one or more timestamps corresponding to each of the one or more identified medical system events occurring on the medical system;
determining, by analyzing the image data of the one or more candidate video clips, whether each of the one or more candidate video segments is an identified video segment that contains the medical procedure event of interest;
and
presenting to a user at least one identified video segment.
