Abstract
Dynamic thermal imaging has improved bulk tissue characterization, but fails to capture subtle thermal property differences in heterogeneous systems. We present focal dynamic thermal imaging (FDTI), a simple, label-free, and high-resolution technology for delineating tissue heterogeneity. Stimulation of focal regions of absorptive materials with a narrow beam, low power, and low cost 405 nm laser locally perturbs the thermal equilibrium. Measurement of phantoms, ex vivo tissue, and in vivo animal models of cancer reveals finite structures of materials and delineates diseased from healthy tissue. Portable FDTI holds promise to capture the heterogeneous nature of malignant tissue.
