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 specif ic 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 th e signal, based on the absorption data, to obtain from a computer device (9) a critically accumulated energy level associated with properties of the specif ic 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.</S DOAB>
