Abstract: The invention provides for a medical apparatus (100, 200, 300) for treating cells of a subject comprising at least one transducer (102, 224) with a vibrating surface (116). The transducer further comprises an applicator (118, 600) for attaching the vibrating surface to an outer surface of the subject (108, 218). The transducer is operable to vibrate at a frequency between 10 Hz and 1000 Hz. The medical apparatus further comprises a controller (104, 222, 230) for controlling the vibration of the transducer. The controller is operable for causing the transducer to vibrate for greater than a predetermined period of time for treating the cells. The predetermined period of time is greater than one hour.

Abstract: A medical apparatus (200, 300, 400, 500) determines the concentration distribution of sonically dispersive elements (606, 2001) within a subject (306, 604, 1004), wherein the medical apparatus comprises: a memory (212) for storing machine executable instructions (224, 226, 228, 230, 232, 318) and a processor (206) for executing the machine executable instructions. Execution of the instructions cause the processor to: receive (100) shear wave data (214) descriptive of the propagation of shear waves (310, 608, 1118) within the subject for at least two frequencies; determine (102) a mechanical property (316, 618, 620) of the subject using the shear wave data at each of the at least two frequencies; determine (104) a power law relationship (218, 702) between the at least two frequencies and the mechanical property; and determine (106) the concentration distribution of the sonically dispersive elements within the subject using the power law relationship and calibration data (222, 704, 800).
