Image stitching for real-time laparoscopic hyperspectral imaging.

ABSTRACT: Hyperspectral imaging (HSI) shows significant promise in the medical field for tissue detection and perfusion assessment. To extend its application to intraoperative diagnosis, laparoscopic cameras combining a high resolution color video and simultaneous HSI were developed. Spatial scanning in these cameras is performed through a push-broom motor driving a line-scan spectrograph. However, long acquisition times and the necessity of absolute immobility for patient and operator currently limit its usability in the operating room. To provide a hyperspectral acquisition alternative to the traditional push-broom motor approach, we have developed an HSI stitching pipeline that enables freehand line scanning. Our method utilizes the dual recording capability of the camera, which has both an RGB a
