摘要： There is provided a method for sensing a sample. The method includes the following steps: first a light beam is directed onto the sample. The sample transmits at least a portion of the light beam to form a transmitted light beam. Next, the transmitted light beam is received at an acoustic transducer. The acoustic transducer absorbs at least a portion of the transmitted light beam and in response generated an acoustic wave. Subsequently, an electrical signal is generated at the acoustic transducer. The electrical signal is generated based on at least a portion of the acoustic wave.

摘要： Various embodiments are described herein for a system and associated method for performing collagen assessment of an object using Photoacoustic Image (PA) data obtained for the object, wherein the method is performed by a processing unit and the method comprises: obtaining beamformed PA image data for the object using at least three wavelengths related to chromophores including collagen, oxyhemoglobin and deoxyhemoglobin, the three wavelengths being less than 1000 nm; performing spectral decomposition on the beamformed PA image data using the three wavelengths to obtain data that is used for generating at least one collagen map; and determining a collagen score for the at least one collagen map.

摘要： Various embodiments are described herein for an imaging device and associated method for performing fluence compensation on a photoacoustic (PA) image of at least a portion of an object for sets of RF acoustic response signals that are obtained using different illumination wavelengths. A first set of RF acoustic response signals is fluence matched to a second set of RF acoustic response signals by determining relative frequency data for first set of RF acoustic response signals relative to the second set of RF acoustic response signals and using the relative frequency data to filter the first set of RF acoustic response signals.
