Document Summary

Spatial compounding: harmonic imaging, b-flow with coded excitation, panoramic imaging, parallel processing, cardiac strain imaging, real time adaptive filtering, volume imaging. Harmonic imaging improves image quality by sending pulses of some frequency into the body but then imaging echoes of frequency double those sent in. Panoramic imaging expands the image beyond the normal limits of the field of view of the transducer. Spatial compounding is the averaging of frames that view the anatomy from different angles. Coded excitation uses a series of pulses and gaps rather than a single driving pulse. Parallel processing is a sophisticated processing technique that enables rapid image acquisition and very high frs. Elastography is an imaging method that presents qualitative tissue stiffness information on the anatomic display and, in some cases, presents quantitative stiffness information. Smoother images, less pixelated: rtaf (xres,sri, post processing function, goals, reduces speckle/noise, enhance borders of tissues, enhance specular reflectors too, see it as an x next to the focus.
