Pulsed wave (PW) Doppler uses the Doppler principle that moving objects change the characteristic of sound waves. By sending short and quick pulses of sound, it becomes possible to accurately measure the velocity of blood in a precise location and in real …

Using Color Doppler Mode, flow velocities within vessels are color-coded! Vessel networks and flow patterns can be laid out in a complex manner. Using Color Doppler, the intensity of the color is a function of velocity. Flow towards and away from the …

Tissue Doppler Imaging allows for measurements of tissue movement, typically performed on the myocardium. This tool is ideal to assess diastolic function of the left ventricle by placing a sample volume at the mitral annulus, where changes in tissue …

Seeing Hypoxia: High-resolution, in vivo oximetry While methods exist for measuring blood oxygenation, they can be invasive, low temporal and/or spatial resolution, superficial or expensive. Because oxy- and deoxyhemoglobin absorb light differently at …

Listen to the Light: Visualizing Deep Optical Signals with High Resolution! PA-Mode Single Wavelength allows the detection and fusion of photoacoustic signals with detailed anatomical images. Using a tuneable near infrared laser, the subject is …

Digital RF-Mode allows users to acquire, digitize, and save the RF (radio frequency) data from the ultra-high frequency ultrasound signal. Ultrasound transducers convert electrical signals into pressure waves which are transmitted into the tissue …

EKV, or E CG-gated K ilohertz V isualization, allows for increased temporal resolution. By averaging multiple cardiac cycles, typical B-mode frame rates are increased from ~300 frames/sec to up to 10,000 frames/sec! This simple and quick acquisition mode …

What is Elastography? Elastography is a non-invasive imaging technique used for detecting tissue stiffness. It is an established method used for detecting and staging liver fibrosis. Low-frequency vibrations, or shear waves, are introduced into the tissue …

Accurate quantification in ultrasound often depends not only on having a great B-mode image but also on limiting movement within the field of view. ECG and respiration gating can pause the image at one specific time within the cardiac cycle and/or only …

PA EKV stands for Photoacoustic ECG-gated Kilohertz Visualization. This unique software allows for photoacoustic imaging with increased temporal resolution and is ideal for cardiovascular applications. By averaging multiple cardiac cycles, typical PA Mode …
