A cineloop is a period of images, stored digitally as a sequence of individual frames. Cineloops recorded at high frame rates may contain more frames than were displayed during the examination.

(CCI) A major limitation of the use of ultrasound contrast agents is the problem that signals from the microbubbles are mixed with those from tissue, so that the distribution of the microbubbles is not optimally displayed either in Doppler or gray scale.
Coherent contrast imaging is a high frame rate implementation of inverting the phase of alternate sound pulses and summing the resulting echoes. The symmetrical signals from linear reflectors are cancelled leaving those from non-linear scatterers, with the advantage that the cancellation is performed without the need to transmit two pulses per image line so that bubble destruction is minimized. Coherent contrast imaging yields best results in the vascular phase of phospholipid microbubbles (such as Definity and SonoVue).

The dwell time (also called ensemble length or packet size) is the transmitting duration of ultrasonic waves focused at one place or the Doppler samples for each line of sight. The reduction of the dwell time is of use if threshold pressures are exceeded.
The sensitivity to slow flow and accuracy of Doppler measurement increase with longer dwell times. With increased dwell times, the frame rates decrease and the capability of Color Doppler images to depict fast changes in hemodynamics is limited.
