Abstract:

BACKGROUND: Infrared thermography as a new technology for non-contact temperature measurement has the advantage of non-invasive, fast and convenient. And computer can be used to reconstruct 3D inner temperature field of biological tissue.
OBJECTIVE: For measurement and reconstruction of temperature field in tumor hyperthermia, to propose new methods of 3D temperature field reconstruction for biological tissue.
METHODS: Infrared thermography technology was applied to measure 2D temperature distribution non-contactly of sliced-biomaterial, which based on bi-heat transfer and information of infrared thermal emitter. Temperature information was converted to gray images to be visualized, and pseudo-colorly processed. In addition, every pixel in infrared thermograph was allocated color and opacity by transfer function, so as to reconstruct temperature field of sliced-biomaterial by volume rendering ray casting algorithm.
RESULTS AND CONCLUSION: Experiment results showed that, based on algorithm of infrared thermal emitter and information obtained from thermal infrared imager was converted to temperature and displayed as pseudo-color. And 3D temperature field obtained from sliced-biomaterial was reconstructed with ray casting. It provides new technology and method for measurement and observation of temperature field in hyperthermia.
