Abstract
Flow estimation is provided. The flow is predicted. A mathematical, logic, machine learning or other model is used to predict flow. For example, the boundary conditions associated with a previous flow, the previous flow, and current boundary conditions are used to predict the current flow. The current flow is corrected using the predicted flow. Velocities may be unaliased based on the predicted flow. The predicted flow may replace the current flow. Prediction may additionally or alternatively be used in determination of lateral or elevational flow.
Claims21
A method for flow estimation in medical diagnostic ultrasound, the method comprising:
- acquiring first velocity data representing flow in a patient at a first time;
- acquiring second velocity data representing flow in the patient at a second time after the first time;
- determining a predicted flow from the first velocity data;
- correcting the second velocity data as a function of the predicted flow;
- and
- displaying an image of the patient as a function of the corrected second velocity data.
In a computer readable storage medium having stored therein data representing instructions executable by a programmed processor for flow estimation in medical diagnostic ultrasound, the storage medium comprising instructions for:
- predicting velocity as a function of flow boundary conditions;
- acquiring, with ultrasound scanning of a patient, estimates of velocity representing the velocity of flow in the patient;
- and
- correcting the estimates of velocity as a function of the predicted velocity.
