Summary: The work deals with the study of the detection possibility of the malignant tumors, particularly sarcoma C-180, in biological objects (mice) by applying a new contactless diagnostic method developed on the basis of acoustic modulation spectroscopy. The comparative analysis of registered amplitude-frequency acoustic spectra of the studied healthy and sick objects allows us to detect and determine the dissemination of malignant tumors.
Key words: Acoustic field modulation, malignant tumors, sarcoma of C-180 type, acoustic spectroscopy, anisotropy of tissues.
