Abstract
A system for guiding ultrasonic probe positioning using scoring-based canonical view simulation model including a catheter coupled to at least a transducer, wherein the at least a transducer is configured to receive ultrasound data, a localization system configured to detect probe position data as a function of a location of the catheter, at least a processor communicatively connected to the at least a transducer and the localization system, and a memory communicatively connected to the at least a processor, and containing instructions configuring the at least a processor to receive the ultrasound data and the probe position data, generate, using a scoring-based canonical view simulation model, a movement vector as a function of the ultrasound data and the probe position data, determine, using the movement vector, real-time guidance data, and display the real-time guidance data to a user through a user interface.
Core Innovation
The disclosed system and method guide ultrasonic probe positioning by combining ultrasound data from a catheter-coupled transducer with probe position data from a localization system. A reinforcement-learning-trained scoring-based canonical view simulation model generates a movement vector and real-time guidance data, including a performance metric that compares user actions with optimal movement predicted by the model. The guidance and metric are displayed to the user in real time through a user interface.
The system also incorporates guidance overlays on ultrasound images or a three-dimensional anatomical model, along with auditory or haptic feedback. In addition, the description details training the model using paired ultrasound and computed tomography data with virtual sensors positioned in computed tomography-derived anatomy. The supplied content does not include the background section, so the problem being solved is not explicitly described in patent.
Claims Coverage
The independent claims cover two inventive features directed to a system and a method for generating real-time ultrasonic probe-position guidance.
System for guiding ultrasonic probe positioning
The system includes a catheter coupled to a transducer, a localization system, a processor, and memory containing instructions. The processor receives ultrasound data and probe position data, uses a reinforcement-learning-trained scoring-based canonical view simulation model to generate a movement vector and real-time guidance data comprising a performance metric by comparing user actions with optimal movement predicted by the model, and displays the guidance and metric to the user in real time.
Method for guiding ultrasonic probe positioning
The method comprises receiving ultrasound data from a catheter-coupled transducer and probe position data from a localization system. The method uses a reinforcement-learning-trained scoring-based canonical view simulation model to generate a movement vector, determines real-time guidance data comprising a performance metric by comparing user actions with optimal movement predicted by the model, and displays the guidance and metric to the user in real time.
The independent claims cover system and method implementations of model-based ultrasonic probe guidance, generating movement vectors and evaluating user actions against predicted optimal movement to output real-time guidance.
