Abstract
Compounding of data representing a same location is provided. The level of compounding is tuned. Different levels of compounding between averaging and selecting a maximum or minimum and/or between minimum and maximum are provided. Ultrasound data to be compounded is weighted. The weights are defined by a smoothly varying functions from a zero value to a unity value or one. The weight for each of the data to be compounded is a function of all of the data to be compounded. One or more variables in the weighting function allows selection of the level of compounding. As a result of these weighting characteristics, a compromise or tuned level of compounding between minimum and selection of a maximum value is provided.
Claims28
A method for compounding ultrasound data representing a same spatial location, the method comprising the acts of:
- (a) weighting first and second data as a function of first and second weights, respectively, the first and second weights each a function of both the first and second data, the first and second weights being other than zero values;
- and
- (b) compounding weighted first and second data.
A system for compounding ultrasound data representing a same spatial location, the system comprising:
- a memory for storing first and second weights, the memory having first and second inputs for receiving first and second data, the first and second weights each responsive to both the first and second data, the first and second weights being other than zero values;
- and
- a filter for weighting the first and second data with the first and second weights, respectively, and for compounding the weighted first and second data.
A method of compounding data representing a same spatial location, the method comprising the acts of:
- (a) weighting first and second data as a function of first and second weights, respectively, the first and second weights responsive to a first function that smoothly varies from a minimum value to a maximum value;
- and
- (b) compounding weighted first and second data.
A system for compounding ultrasound data representing a same spatial location, the system comprising:
- a memory for storing first and second weights, the first and second weights responsive to a first function that varies smoothly from a zero value to a unity value;
- a filter for weighting the first and second data with the first and second weights, respectively, and for compounding the weighted first and second data.
A method of compounding ultrasound data representing a same spatial location, the method comprising the acts of:
- (a) selecting in response to user input a level of compounding from a range between minimum and a maximum of first and second data;
- and
- (b) compounding the first and second data as a function of the level of compounding.
