A device for imaging an object of interest (401, 402). The apparatus is responsive to absorption of primary electromagnetic radiation, an ultrasound apparatus (404) adapted to emit ultrasound of at least two different frequencies (405) onto an 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 ultrasound (405). |
