PA EKV
High frame-rate cardiac imaging with photoacoustics
Measure Oxygenation in the Heart with Greater Precision
Allows for photoacoustic imaging with increased temporal resolution.
PA EKV
Long axis view of a mouse left ventricle showing oxygen saturation (red, white, blue) in the anterior myocardium coregistered with anatomical ultrasound.
Single wavelength PA EKV
Longitudinal view of the common carotid artery of a mouse coregistered with anatomical ultrasound.
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 frame rates are increased from approximately 5 frames/sec to hundreds of frames/sec allowing visualization of dynamic changes in photoacoustic signal over the entire cardiac cycle.
Unlock the ability to detect oxygen saturation and total hemoglobin dynamically throughout the cardiac cycle for assessment of:
- Myocardial hemodynamics
- Myocardial hypoxia and ischemia
- Progression of angiogenesis
Multispectral PA EKV imaging also opens up molecular imaging cardiac applications using photoacoustic contrast agents such as:
- Cell tracking
- Biomarker imaging
