  Multispectral and hyperspectral imaging (MSI/HSI) can provide clinically
relevant information on morphological and functional tissue properties.
Application in the operating room (OR), however, has so far been limited by
complex hardware setups and slow acquisition times. To overcome these
limitations, we propose a novel imaging system for video-rate spectral imaging
in the clinical workflow. The system integrates a small snapshot multispectral
camera with a standard laparoscope and a clinically commonly used light source,
enabling the recording of multispectral images with a spectral dimension of 16
at a frame rate of 25 Hz. An ongoing in patient study shows that multispectral
recordings from this system can help detect perfusion changes in partial
nephrectomy surgery, thus opening the doors to a wide range of clinical
applications.
