For Real-time Monitoring of Functional Processes

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 different wavelengths, photoacoustic imaging can be used to generate a high resolution parametric map of the oxygen saturation of blood completely non-invasively.

This allows for the real-time monitoring of functional processes with the added advantage of having this oximetry data fused with high resolution anatomical images.

Oxy-Hemo mode can be used for:

• Hypoxia assessment within the tumor microenvironment
• Ischemia measurement in stroke and myocardial infarction
• Longitudinal assessment of angiogenesis
• Hemodynamic response to therapy
• Studies of placental oxygenation

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. Learn more.
