Abstract
In an ultrasound imaging system, an ultrasound scanning assembly (USC) provides volume data (VD) resulting from a three-dimensional scan of a body (BDY). A region of interest detector (RDT) detects a region within the volume data (VD) characterized by a variation of at least one data parameter, which exceeds a margin. A slice generator (SLG) may then generates-slices (SX) from the region that has been detected. These slices (SX) can be displayed on a display device (DPL).
Claims9
An ultrasound imaging system comprising:
- an ultrasound scanning assembly arranged to provide volume data resulting from a three-dimensional scan of a body;
- a region of interest detector arranged to detect a region within the volume data characterized by a variation of at least one data parameter, which exceeds a margin, by comparison of a set of local values, which have been determined for the at least one parameter based on a portion of the volume data, with at least one of the following:
- (a) a set of global values, which have been determined for the at least one parameter based on the volume data in its entirety;
- and
- (b) another set of local values, which have been determined for the at least one parameter based on another, adjacent portion of the volume data.
6-7. (canceled)
A method of ultrasound imaging involving an ultrasound scanning assembly arranged to provide volume data resulting from a three-dimensional scan of a body, the method comprising:
- a region of interest detection step in which a region of interest within the volume data characterized by a variation of at least one data parameter, which exceeds a margin, is detected by comparison of a set of local values, which have been determined for the at least one parameter based on a portion of the volume data, with at least one of the following:
- (a) a set of global values, which have been determined for the at least one parameter based on the volume data in its entirety;
- and
- (b) another set of local values, which have been determined for the at least one parameter based on another, adjacent portion of the volume data.
A computer program product for an ultrasound imaging system comprising
- an ultrasound scanning assembly arranged to provide volume data resulting from a three-dimensional scan of a body:
- a programmable processor,
- the computer program product comprising a set of instructions, which when loaded into the programmable processor, enables the programmable processor to carry out a region of interest detection step in which a region of interest within the volume data characterized by a variation of at least one data parameter, which exceeds a margin, is detected by comparison of a set of local values, which have been determined for the at least one parameter based on a portion of the volume data, with at least one of the following:
- a) a set of global values, which have been determined for the at least one parameter based on the volume data in its entirety;
- and
- b) another set of local values, which have been determined for the at least one parameter based on another, adjacent portion of the volume data.
