Monitoring of Pediatric Inflammatory Bowel Diseases Using Multispectral Optoacoustic Tomography

In MSOT, laser light is emitted into the target tissue via a handheld probe. Thermoelastic expansion of various molecules in the target area generates ultrasound waves that are detected by the transducer. The detected signals are reconstructed into images using algorithms. Spectral analysis of the optoacoustic signal at different wavelengths in the near-infrared range can detect individual chromophores, such as oxygenated and deoxygenated hemoglobin.
