An apparatus for imaging an object of interest (401, 402), the apparatus comprising an ultrasound device (404) adapted to emit ultrasonic waves (405) of at least two different frequencies onto the object of interest (401, 402), and an electromagnetic radiation detector (406) adapted to detect electromagnetic fluorescence radiation (407) emitted by the object of interest (401, 402) in response to an absorption of primary electromagnetic radiation and in response to the ultrasonic waves (405). |
