'Incorporating the latest advances in technology, the CTS-6000 digital B/W ultrasound system provides exceptional imaging quality and complete diagnostic capabilities. It is equipped with extensive analysis package, super broadband multifrequency probes and disk storage capacity, a complete system that fully meets different clinical needs.
CTS-6000 sets a new standard for digital ultrasound imaging.'

In a color map, colors are allocated to Doppler shift frequencies corresponding to flow. Color (colour, Brit.) maps may also display Doppler amplitude, signal power, variance, or the gray levels of the B-mode image.

See also Color Amplitude Imaging, Color Priority, and Color Saturation.

The color priority determines which signal of B-mode and Doppler, detected from the same location will be displayed in a given pixel. Low color priorities will allow solid tissue to conceal Doppler shifts at the same location; a high priority ensures that color will overwrite the gray scale image.
Also called color-echo write priority or angio write priority.

(CEUS) Contrast agents increase the reflection of ultrasonic energy, improve the signal to noise ratio and caused by that the detection of abnormal microvascular and macrovascular disorders. Contrast enhanced ultrasound is used in abdominal ultrasound (liver sonography) as well as in cerebrovascular examinations e.g., for an accurate grading of carotid stenosis. The used contrast agents are safe and well tolerated.

The quality of the enhancement depends on:
The additional use of ultrasound contrast agents (USCAs) may overcome typical limitations like poor contrast of B-mode imaging or limited sensitivity of Doppler techniques. The development of new ultrasound applications (e.g., blood flow imaging, perfusion quantification) depends also from the development of pulse sequences for bubble specific imaging. In addition, contrast enhanced ultrasound improves the monitoring of ultrasound guided interventions like RF thermal ablation.

The dynamic range in signal processing is the range between the minimum low intensity and maximum high intensity signals that a system is capable of displaying.
