Abstract
Various systems are provided for an ultrasound imaging system. In one example, a method comprises learning a travel path profile and one or more pressures applied along the travel path profile in response to an external handle force and acquiring an ultrasound image along the travel path profile by applying one or more pressures against an acquisition surface of a patient via a robot without the external handle force.
Claims18
A method, comprising:
- defining an anatomical structure model using machine learning to identify one or more anatomical structures of interest;
- learning a travel path profile to a structure of interest of the one or more anatomical structures of interest and one or more pressures applied along the travel path profile in response to an external handle force directly applied to a probe handle of a probe via a user;
- receiving confirmation that a correct ultrasound image has been acquired;
- setting a scan protocol for an anatomical region;
- and
- acquiring an ultrasound image along the travel path profile by applying one or more forces against an acquisition surface of a patient via a robot without the external handle force;
- wherein the travel path profile is one travel path profile of a plurality of travel path profiles corresponding to a scan protocol type, wherein the plurality of travel path profiles in the scan protocol are executed in an order different than the order learned.
4 more elements
A system, comprising:
- an ultrasound device comprising an ultrasound probe;
- a robot comprising an arm configured to couple to the ultrasound probe;
- and
- a controller with computer-readable instructions stored on non-transitory memory thereof that when executed enable the controller to:
- adjust the robot to a learning mode to learn a travel path profile to a structure of interest;
- wherein the learning mode comprises a velocity control mode, the velocity control mode comprising translating a handle force of the ultrasound probe into a velocity command, wherein the handle force comprises an external force directly applied to a handle of the ultrasound probe via a user's hand;
- instruct the robot via a proportional-integral-derivative controller to actuate the ultrasound probe along an x-y plane, wherein the robot applies a pressure to the ultrasound probe in combination with the pressure applied by the user's hand;
- disable the robot from acquiring an ultrasound image when the handle force is applied;
- adjust the robot to an image acquisition mode in response to an absence of the external force being applied to the ultrasound probe;
- and
- acquire the ultrasound image along a travel path, wherein the travel path profile is one travel path profile of a plurality of travel path profiles corresponding to a scan protocol type, wherein the plurality of travel path profiles in a scan protocol are executed in an order different than the order learned.
8 more elements
A method for acquiring an ultrasound image, comprising:
- learning a plurality of travel path profiles, each travel path profile comprising a travel path, one or more velocities, one or more probe forces, and one or more orientations, wherein the learning is in response to an external force being applied by a user's hand directly to a handle of an ultrasound probe to which a hand of a robot is coupled, wherein one or more velocities are learned via measurements taken by a force sensor and a force gauge based on a handle force and wherein one or more probe forces and one or more orientations are learned based on probe forces applied angled to an acquisition surface of a patient;
- and
- acquiring the ultrasound image via only the robot in response to the external force being absent, wherein the robot is signaled to execute one or more velocities, one or more probe forces, and one or more orientations learned along the plurality of travel path profiles, wherein the ultrasound image is acquired from a travel path of the plurality of travel path profiles corresponding to a scan protocol type, wherein the plurality of travel path profiles in the scan protocol are executed in an order different than the order learned;
- wherein at least one of the probe forces is dynamically adjusted relative to the learned pressure based on patient body type.
