If your detection geometry doesn't have full view, then you will not reconstruct the point source exactly. There are some details about this included in the examples under the photoacoustic image reconstruction heading in the k-Wave help.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/implication-about-p-p_rms-p_max-and-p_final#post-7306 Fri, 20 Mar 2020 04:31:03 +0000 jackYANG 7306@http://www.k-wave.org/forum/ <p>Hello everyone,<br /> I used kwave to reconstruct the TR initial pressure distribution,in my opinion, this method can achieve the refocus of focus,just like the TR focus based on the virtual point sound source.But I have a problem,what is the p0_recon mean?it is p p_rms p_max and p_final?I don't know why is there a negative pressure on the sound axis(radial direction ),Finally, I plot the sound pressure distribution of the axial sound, which is like a pulse shape.Can someone explain it here?thanks.<br /> Jack </p>
