摘要： Embodiments for ultrasound data processing in an ultrasound system are disclosed. In one embodiment, a mapping table, in which linear operation information is associated with a plurality of diagnostic modes, is stored in a storage unit. If there is an instruction to select at least one of the diagnostic modes, then an ultrasound data acquisition unit transmits/receives ultrasound signals to/from a target object to thereby acquire ultrasound data according to the selected diagnostic mode. A processing unit forms an ultrasound data matrix based on the ultrasound data and retrieves the linear operation information associated with the selected diagnostic mode from the mapping table to form linear operation matrices. Further, the processing unit performs a matrix operation of the ultrasound data matrix and the linear operation matrices.
