An apparatus (1) for selective cell or virus destruction within a living organism (2) comprises an acoustic transmitter (6), arranged to transmit an acoustic signal into a first portion (3) of the organism, and a control unit (7) designed to control characteristics associated with the acoustic signal, including to set the frequency for the signal to a value which causes specific cells (5) within the first cellular portion (3) to be damaged. The apparatus further comprises an absorption measuring device (8) which provides acoustic absorption data from a second portion of the organism, said second cellular portion (4) including the specific cells (5). Further, the control unit (7) is arranged to control characteristics such as the power and/or intensity of the signal, based on the absorption data, to obtain from a computer device (9) a critically accumulated energy level associated with properties of the specific cells (5), and, during a period of exposure, to control the power of the acoustic signal in such a way that the total energy of the signal during the period of exposure will not exceed a critically accumulated energy level.
