coronary bypass minimally invasive surgeries in beagles has been carried out by

Nakagawa et al. [136] using IR imaging. In addition, a physiological saline of

different temperatures was injected through the endoscope channel to see the

changes in cortical images. They concluded that transendoscopic IR imaging

(7–14 mm) may provide a noninvasive functional angiography. Stefanadis et al.

[137] have developed a thermocouple-based thermography catheter and demon-

strated in a human in vivo trial that thermal gradients between healthy and

neoplastic tissue zones could be a useful criterion in the diagnosis of malignancy

in tumors of the bladder. They found significant temperature differences (e.g.,

1 8C) between patients with benign and malignant tumors. ...
