    摘要： Systems and methods for improving the quality of ultrasound images made up of a combination of multiple sub-images include giving more weight to sub-image information that is more likely to improve a combined image quality. Weighting factor information may be determined from the geometry (e.g., angle or path length) of a location of one or more specific transducer elements relative to a specific point within a region of interest or a region of an image. In some embodiments, any given pixel (or other discrete region of an image) may be formed by combining received echo data in a manner that gives more weight to data that is likely to improve image quality, and/or discounting or ignoring data that is likely to detract from image quality (e.g., by introducing noise or by increasing point spread).

    摘要： A method and apparatus for detecting address range overlaps. According to one embodiment, a first mask is generated for a first address range and a second mask is generated for a second address range. A first AND operation is performed on the first address range and the second mask to output a first temporary value. A second AND operation is performed on the second address range and the first mask to output a second temporary value. The first temporary value is then compared to the second temporary value to detect an overlap between the first address range and the second address range. According to an alternate embodiment, a first mask is generated for a first address range and a second mask is generated for a second address range. The first mask is then compared to the second mask to detect an overlap between the first address range and the second address range.

    摘要： An apparent point-source transmit transducers comprises a substantially constant-thickness shell of piezoelectric material in a shape of a spherical-section. Such transducers may be sized such that a single apparent point-source transmit transducer may produce ultrasound waveforms with substantial energy in a medium to be imaged. Use of such transducers in three-dimensional ping-based imaging may permit deeper and higher quality imaging than may be possible with conventional transducers.

    摘要： A scheduling unit is described for scheduling an execution order of a first instruction of a first type and a second instruction of a second type in an instruction stream where the second instruction precedes the first instruction. The scheduling unit comprises a table that records address component identifiers corresponding to the second instruction. An address comparator is coupled to the table. The address comparator compares address component identifiers that corresponds to the first instruction with address component identifiers on the table. The scheduling unit schedules the first instruction to be executed ahead of the second instruction when the address component identifiers differ from the address component identifiers on the table.
