“…Correlation of temperature history with cellular responses for short non-isothermal laser exposures has been a longstanding challenge. 3 Future surgical procedures will likely employ intraoperative thermal imaging 4 with feedback control of laser dose based on known cell-specific thermal damage kinetics 5,6 to ensure desired therapeutic effects. However, predicting cellular outcomes based on laser dose kinetics is inherently difficult.…”

Abstract. We measured threshold temperatures for cell death resulting from short (0.1-1.0 s) 514-nm laser exposures using an in vitro retinal model. Real-time thermal imaging at sub-cellular resolution provides temperature information that is spatially correlated with cells at the boundary of cell death, as indicate by post-exposure fluorescence images. Our measurements indicate markedly similar temperatures, not only around individual boundaries (single exposure), but among all exposures of the same duration in a laser irradiance-independent fashion. Two different methods yield similar threshold temperatures with low variance. Considering the experimental uncertainties associated with the thermal camera, an average peak temperature of 53 ± 2• C is found for laser exposures of 0.1, 0.25, and 1.0 s. Additionally, we find a linear relationship between laser exposure duration and time-averaged integrated temperature. The mean thermal profiles for cells at the boundary of death were assessed using the Arrhenius rate law using parameter sets (frequency factor and energy of activation) found in three different articles.

“…The real-time anatomical and pathophysiological information provided by ioTI may contribute to safely improving the extent of tumor resection. 44 The presence of a tumor often alters the homeostasis of the surrounding tissue and ioTI measurements are sensitive to this change. Changes in homeostasis that affect temperature can be due to low density in tumor microvessels, 45,46 edema in the surrounding tissues due to increases in the volume of white matter caused by tumor growth, 45,46 lower metabolism in the cortex overlying intracranial tumors, due to the "disconnection effect" caused by edema, 45,46 or tumor necrosis, typically caused by reduction of tumor vasculature and metabolic activity.…”

“…Limitations of this technology include a lack of software that can autodelineate the tumor margin, a need for cameras with higher spatial resolution, and limited tissue penetration depth (<0.5 mm). 44 Ultimately, infrared thermography could become a vital addition to high-resolution neurosurgical microscopes that can accurately distinguish between normal and cancerous tissue using diverse multimode technologies.…”
