As you have focussed detectors you will probably do better if you use a reconstruction algorithm that incorporates the directional sensitivity of the detectors.</p> <p>Best wishes,<br /> Ben </p> http://www.k-wave.org/forum/topic/pa-reconstruction-using-focussed-and-non-focussed-transducer-forward-data#post-6701 Thu, 03 Jan 2019 12:12:15 +0000 prabodhkp 6701@http://www.k-wave.org/forum/ <p>Hi,</p> <p>Can we use directly use the universal back-projection (UBP) algorithm for photo-acoustic (PA) reconstruction using PA forward data generated from focused transducer array? Or, I would need to make certain corrections to the algorithm/data ? </p> <p>Thank you.</p> <p>Regards<br /> Prabodh </p>
