The goal of this research was to design and evaluate an infrared (IR) prototype device for the detection of the blood temperature during a surgical operation for coronary bypass implantation. The idea was to study a low cost portable device to be placed near the region of interest. We chose a pyroelectric sensor for its high qualitycost ratio. Because this kind of sensor detects only a variable infrared source, we used an electromechanical chopper for modulating the radiation. The output signal was analysed using a dedicated electronics; then an acquisition board is employed for processing the signal using a PC. Prototype assessment was made with laboratory equipment and in vivo measurements during surgical operation of a little pig.

Abstract
The goal of this research was to design and evaluate an infrared (IR) prototype device for the detection of the blood temperature during a surgical operation for coronary bypass implantation. The idea was to study a low cost portable device to be placed near the region of interest. We chose a pyroelectric sensor for its high qualitycost ratio. Because this kind of sensor detects only a variable infrared source, we used an electromechanical chopper for modulating the radiation. The output signal was analysed using a dedicated electronics; then an acquisition board is employed for processing the signal using a PC. Prototype assessment was made with laboratory equipment and in vivo measurements during surgical operation of a little pig.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
