Evaluating clinical near-infrared surgical camera systems with a view to optimizing operator and computational signal analysis.

ABSTRACT:

Significance

As clinical evidence on the colorectal application of indocyanine green (ICG) perfusion angiography accrues, there is also interest in computerizing decision support. However, user interpretation and software development may be impacted by system factors affecting the displayed near-infrared (NIR) signal.

Aim

We aim to assess the impact of camera positioning on the displayed NIR signal across different open and laparoscopic camera systems.

Approach

The effects of distance, movement, and target location (center versus periphery) on the displayed fluorescence signal of different systems were measured under electromagnetic stereotactic guidance from an ICG-albumin model and in vivo during surgery.

Results

Systems displayed distinct fluorescence
