Recent developments in optical spectroscopic techniques have permitted in vivo, in situ cellular and molecular sensing and imaging to allow for real-time tissue characterization, functional assessment, and intraoperative guidance. The small area sensed by these probes, however, presents unique challenges when attempting to obtain useful tissue information in-vivo due to the need to maintain constant distance or contact with the target, and tissue deformation. In practice, the effective area can be increased by translating the tip of the probe over the tissue surface and generating functional maps of the underlying tissue response. However, achieving such controlled motions under manual guidance is very difficult, particularly since the probe is typically passed down the instrument channel of a flexible endoscope. This paper describes a force adaptive multi-spectral imaging system integrated with an articulated robotic endoscope that allows a constant contact force to be maintained between the probe and the tissue as the robot tip is actuated across complex tissue profiles. Detailed phantom and ex-vivo tissue validation is provided.

Mountney P, Giannarou S, Elson D, et al., 2009, Optical biopsy mapping for minimally invasive cancer screening, Pages: 483-490, ISSN: 0302-9743
The quest for providing tissue characterization and functional mapping during minimally invasive surgery (MIS) has motivated the development of new surgical tools that extend the current functional capabilities of MIS. Miniaturized optical probes can be inserted into the instrument channel of standard endoscopes to reveal tissue cellular and subcellular microstructures, allowing excision-free optical biopsy. One of the limitations of such a point based imaging and tissue characterization technique is the difficulty of tracking probed sites in vivo. This prohibits large area surveillance and integrated functional mapping. The purpose of this paper is to present an image-based tracking framework by combining a semi model-based instrument tracking method with vision-based simultaneous localization and mapping. This allows the mapping of all spatio-temporally tracked biopsy sites, which can then be re-projected back onto the endoscopic video to provide a live augmented view in vivo, thus facilitating re-targeting and serial examination of potential lesions. The proposed method has been validated on phantom data with known ground truth and the accuracy derived demonstrates the strength and clinical value of the technique. The method facilitates a move from the current point based optical biopsy towards large area multi-scale image integration in a routine clinical environment. © 2009 Springer-Verlag.
