Systems for ultrasound beam forming data control
Disclosed are systems and methods which efficiently control storage of and/or access to data which includes repetitive data or data which is used by different modes, processes, etcetera. Embodiments provide control for storage of and/or access to large amounts of data used in ultrasound system beam forming for image generation using a hierarchy of sequencers for controlling storage of and/or access to data. A frame sequencer may provide control at a frame level while an address sequencer is implemented to provide control at a data access level.
1. An ultrasound imaging system comprising:
a memory containing a multi-dimensional array storing information for a number of beam forming parameters of a plurality of lines, wherein the beam forming parameters for each line are individually locatable based on one or more offsets from a reference; and
a memory control having a hierarchy of sequencers controlling access to said information stored in said multi-dimensional array, wherein said hierarchy of sequencers includes a frame sequencer configured to provide a number of line parameters to be used in creating a frame of ultrasound data and an address sequencer that is configured to compute an address for locating the information in the multi-dimensional array for the beam forming parameters based on one or more offsets that are determined from the line parameters provided by the frame sequencer.
2. The system of claim 1 , wherein the one or more offsets is associated with at least one of an image mode, an image zone, and an image line.
3. The system of claim 1 , wherein the beam forming parameters are stored in the multi-dimensional array at the address that is computed by the address sequencer.
4. The system of claim 1 , wherein beam forming parameters are stored at a location that is referenced by a pointer that is stored in the multi-dimensional array at an address that is computed by the address sequencer.
5. The system of claim 1 , wherein said frame sequencer provides control on a line-by-line basis.
6. The system of claim 1 , wherein said frame sequencer is initialized for use in different imaging modes by providing parameters thereto.
7. The system of claim 1 , wherein said reference is a base address and the address for locating the information for the beam forming parameters for each line is determined as an offset from said base address in at least one dimension of said multi-dimensional array.
8. The system of claim 1 , wherein said hierarchy of sequencers are implemented in one or more application specific integrated circuits.
9. The system of claim 1 , wherein said ultrasound imaging system comprises a portable diagnostic ultrasound instrument.
10. The system of claim 1 , wherein said multi-dimensional array comprises at least a three dimensional array.
