Abstract

A method, system, and computer program product for predictive maintenance. A method may include receiving operation data associated with one or more injection systems, wherein the operation data includes one or more operation parameters associated with one or more operations of the one or more injection systems; determining one or more prediction scores for the one or more injection systems based on the operation data, wherein the one or more prediction scores include one or more predictions of one or more operation failures or misuses for the one or more injection systems; and providing maintenance data associated with the one or more operation failures or misuses, wherein the maintenance data is based on the one or more prediction scores.

First claim

The invention claimed is:

1. A predictive maintenance system comprising:
one or more injection systems including an injector including an injector motor configured to one of: (i) move a plunger to deliver fluid from a syringe of the injector and (ii) power a pump to pump fluids from a fluid source of the injector;
one or more force sensors configured to measure a force of the injector motor of the injector needed to one of: (i) move the plunger to deliver fluid from the syringe of the injector and (ii) power the pump to pump fluids from the fluid source of the injector, for the one or more injection systems for one or more injection operations;
a computer system comprising one or more processors programmed or configured to:
receive operation data associated with the one or more injection systems, wherein the operation data includes one or more operation parameters associated with the one or more injection operations of the one or more injection systems, and wherein the one or more operation parameters include for each of the one or more injection systems the force of the injector motor thereof measured by the one or more force sensors for the one or more injection operations;
determine one or more prediction scores for the one or more injection systems based on the operation data including for each of the one or more injection systems the force of the injector motor thereof measured by the one or more force sensors for the one or more injection operations, wherein the one or more prediction scores include one or more predictions of one or more operation failures or misuses for the one or more injection systems associated with a build-up of wear, contrast and/or dirt in connection therewith such that an effect of the build-up of wear, contrast and/or dirt for each of the one or more injection systems is determined by a comparison of the force of the injector motor thereof for a current or more recent injection operation to the force of the injector motor thereof for one of a previous injection operation and a calibration operation of the injector motor;
provide maintenance data associated with the one or more operation failures or misuses, wherein the maintenance data is based on the one or more prediction scores; and
disable, based on the maintenance data, the one or more injection systems from performing an injection operation.

2. The predictive maintenance system of claim 1 , wherein the maintenance data includes a prompt to a user to initiate at least one maintenance action associated with the one or more injection systems.

3. The predictive maintenance system of claim 2 , wherein the at least one maintenance action includes at least one of the following: scheduling a service for the one or more injection systems, operating the one or more injection systems in a specific manner indicated by the maintenance data, or any combination thereof.

4. The predictive maintenance system of claim 1 , wherein the one or more operation parameters include a cleanliness rating associated with a cleanliness of the one or more injection systems, the predictive maintenance system further comprising:
one or more image capture devices configured to capture one or more images of the fluid source and the injector of the one or more injection systems, and wherein the one or more processors are further programmed or configured to:
determine the cleanliness rating based on the one or more images.

5. The predictive maintenance system of claim 1 , wherein the one or more operation failures or misuses for the one or more injection systems include at least one of the following: failure of an electrical component, failure of a software component, failure of a mechanical component, receiving, with the one or more injection systems, user input from a user of the one or more injection systems that causes the one or more injection systems to operate contrary to one or more predefined operation thresholds, or any combination thereof.

6. A computer program product for predictive maintenance, the computer program product comprising at least one non-transitory computer-readable medium comprising one or more instructions that, when executed by at least one processor, cause the at least one processor to:
control one or more force sensors to measure a force of an injector motor of an injector needed to one of: (i) move a plunger to deliver fluid from a syringe of the injector and (ii) power a pump to pump fluids from a fluid source of the injector, for one or more injection systems for one or more injection operations;
receive operation data associated with the one or more injection systems, wherein the operation data includes one or more operation parameters associated with the one or more injection operations of the one or more injection systems, and wherein the one or more operation parameters include for each of the one or more injection systems the force of the injector motor thereof measured by the one or more force sensors for the one or more injection operations;
determine one or more prediction scores for the one or more injection systems based on the operation data including for each of the one or more injection systems the force of the injector motor thereof measured by the one or more force sensors for the one or more injection operations, wherein the one or more prediction scores include one or more predictions of one or more operation failures or misuses for the one or more injection systems associated with a build-up of wear, contrast and/or dirt in connection therewith such that an effect of the build-up of wear, contrast and/or dirt for each of the one or more injection systems is determined by a comparison of the force of the injector motor thereof for a current or more recent injection operation to the force of the injector motor thereof for one of a previous injection operations and a calibration operation of the injector motor;
provide maintenance data associated with the one or more operation failures or misuses, wherein the maintenance data is based on the one or more prediction scores; and
disable, based on the maintenance data, the one or more injection systems from performing an injection operation.

7. The computer program product of claim 6 , wherein the maintenance data includes a prompt to a user to initiate at least one maintenance action associated with the one or more injection systems.

8. The computer program product of claim 7 , wherein the at least one maintenance action includes at least one of the following: scheduling a service for the one or more injection systems, operating the one or more injection systems in a specific manner indicated by the maintenance data, or any combination thereof.

9. The computer program product of claim 6 , wherein the one or more operation parameters include a cleanliness rating associated with a cleanliness of the one or more injection systems, and wherein the one or more instructions further cause the at least one processor to:
control one or more image capture devices to capture one or more images of the fluid source and the injector of the one or more injection systems; and
determine the cleanliness rating based on the one or more images.

10. The computer program product of claim 6 , wherein the one or more operation failures or misuses for the one or more injection systems include at least one of the following: failure of an electrical component, failure of a software component, failure of a mechanical component, receiving, with the one or more injection systems, user input from a user of the one or more injection systems that causes the one or more injection systems to operate contrary to one or more predefined operation thresholds, or any combination thereof.
