| Summary: | In this letter, we present a method named microwave-acoustic phasoscopy (MAPC) by collecting both scattered microwave energy and microwave-induced thermoacoustic wave energy for tissue characterization. Different from conventional amplitude and spectrum analysis, we propose to evaluate the microwave-acoustic phase for tissue characterization. Theoretical analysis and experiment verification are performed to show a good agreement. Four different biological tissues are well differentiated in phase region using the proposed MAPC. This attempt of exploring intrinsic relationship between scattered microwave and induced thermoacoustic signals simultaneously provides phase contrast for tissue characterization, showing significant potential in developing phase-contrast imaging prototype based on MAPC theory. |
