Acoustic quantification (AQ) is a noninvasive technique which provides online left ventricular (LV) area/volume waveforms. The filling portion of the AQ waveform can be used to assess LV diastolic properties. Analysis of signal-averaged AQ curves enhances the waveforms and allows reliable, quantitative, and automated analysis.

Color kinesis uses automated border detection technology based on backscatter data to display both the magnitude and timing of endocardial motion in real time. The color kinesis display superimposes a color overlay on the two-dimensional echocardiographic image; the number of color pixels represents the magnitude of endocardial motion, while the different colors represent the timing of endocardial motion according to a predefined color scheme.

- The study investigated how temperature influences the stability of two contrast agents, Albunex and FS069, by examining their reflective properties under high dose ultrasound.
- The experimental setup involved using a latex balloon in a water tank, with varying temperatures (8°C, 22°C, 37°C) and ultrasound power levels (0, 20, 25, 30 dB) to assess changes in video intensity over time.
- Results showed that higher temperatures improved contrast enhancement, while a significant decrease in intensity over time was more evident in Albunex compared to FS069, highlighting the need for temperature control to maintain consistency in contrast enhancement.
