From Verathon Inc.;
'The BladderScan® BVM 6500 enables physicians quickly and noninvasively to determine UEBW (ultrasound estimated bladder weight) and bladder volume using 3-dimensional V-mode® ultrasound. The BVM 6500 was designed to assist in diagnosis of bladder hypertrophy secondary to obstruction.'

(CWD) Continuous wave (CW) Doppler is an ultrasound imaging mode, which records blood flow velocities along the length of the beam. Continuous wave Doppler uses different crystals to send and receive the signal. The transducer operating in continuous wave mode utilizes one half of the elements and is continuously sending sound waves of a single frequency while the other half is continuously receiving the reflected signals.
The advantages of a continuous wave transducer are a high sensitivity and no Nyquist limit. CW Doppler does not alias but has no depth precision and large gate. The beat frequency is the Doppler shift. CW Doppler echocardiography employs this technique to record the flow of blood through the cardiovascular system.

Cross talk is an ultrasound artifact in which strong sound signals in one directional channel leak into another, appearing as a mirror image of the spectral display on the opposite side of the baseline. Cross talk distinguishes the condition of undesired crossover of transmitted sound waves into the receiving transducer in a continuous wave Doppler system.
Also called Mirror Artifact.

Duplication artifacts can be created through diffraction and refraction on interfaces, also if the acoustical impedances of tissue is too much different and the ultrasound is reflected multiple on tissue layers, where the detected echo does not come from the shortest sound path.
