Classification: CPC A  G | IPC A  G

Claim 15:
16. A method for multiplex photoacoustic imaging of a volume, the method comprising:
(a) contacting the volume with a contrast agent comprising a plurality of radiation-absorbing components, each member of the plurality of radiation-absorbing components comprising a metallobacteriochlorin, a metallochlorin, or a combination thereof, at least one of which comprises a radiation-absorbing component selected from the group consisting of MBC-1, MBC-2, and MBC-3, wherein M is selected from the group consisting of copper and manganese;
(b) exposing the volume to radiation with a wavelength of 650-1070 nm, wherein the radiation is calibrated to wavelengths that are differentially absorbed by the plurality of radiation-absorbing components;
(c) differentially detecting ultrasonic waves generated in the volume by the radiation as it is differentially absorbed by the plurality of radiation-absorbing components; and
(d) generating a photoacoustic image therefrom of the volume or a part thereof containing the administered contrast agent, wherein the photoacoustic image is generated from the differentially detecting ultrasonic waves.
