Issue Date: | 2013 | Source: | Gao, F., Zheng, Y., Feng, X., & Ohl, C.-D. (2013). Thermoacoustic resonance effect and circuit modelling of biological tissue. Applied Physics Letters, 102(6). | Series/Report no.: | Applied physics letters | Abstract: | In this letter, thermoacoustic resonance effect is predicted from theoretical analysis with series resistor-inductor-capacitor resonance circuit model and then observed experimentally using muscle tissue illuminated by multi-pulse microwave source. Through model fitting, the circuit parameters are extracted to characterize quantitatively the resonant response of the tissue. Coherent demodulation is applied to obtain the enhanced signal-to-noise ratio and spatial information by treating tissue as a communication channel. This physical phenomenon shows significantly higher sensitivity than conventional single microwave pulse induced thermoacoustic effect, enabling the potential design of low-power thermoacoustic imaging device for portable and on-site diagnosis. | URI: | https://hdl.handle.net/10356/100405 http://hdl.handle.net/10220/10992 |
