Abstract

Various examples are provided for photoacoustic image reconstruction and processing utilizing a backprojection approach. In one example, among others, a method for producing an image with a photoacoustic imaging system includes scanning an object with a plurality of light beams, detecting a plurality of acoustic signals produced by the light beams, and generating a reconstructed image from the plurality of acoustic signals by filtered backprojection (FBP) that utilizes a weighted ramp filter. In another example, a system includes a plurality of acoustic detector units and a processing unit. The acoustic detector units can receive an acoustic wave and convert it to time dependent electrical signals. The processing unit can reconstruct an image of the subject from the time-dependent electrical signals by FBP that utilizes a weighted ramp filter. In another example, non-transitory computer readable medium stores a program that can cause a processing unit to reconstruct an image.
