Ultrasound images can be manipulated for evaluation in various ways. Post processing includes: 3D imaging analysis, multi planar reconstruction (MPR), maximum intensity projection (MIP), etc.

An imaging direction, backwards relative to a short axis of the human body from the back to the front.

Power in ultrasound describes the energy generated by a wave or in a signal per unit of time. The power is measured in watts (W) and is proportional to the square of the amplitude.

(PD) Power Doppler imaging (PDI) is a Doppler technique, sensitive to low blood flow, allowing a complete visualization of detailed vascular blood structure. This medical imaging method is useable for detecting microbubbles during myocardial contrast echocardiography.

See also Resistive Index.

A power map shows the range of colors corresponding to the power of the Doppler signal in a power mode display.
