    I am high school student form Turkey and I am preparing a research paper on this topic, mostly on photoacoustic effect and phostoacousic imaging. This presentation was incredibely beneficial for me. Hoping to see photoacoustics more on future.

    Thank you Prof. Wang, that was a video, that persuaded me to start with optoacoustic imaging, and that was about 8 years ago!

    This is absolutely unbelievable. I had no idea this imaging modality even existed. incredible work.

    I participated in Photoacoustic research at the University of Massachusetts in Boston during my undergraduate years. I will be giving a presentation on photoacoustics in a few days, and this seminar has been very helpful.
    There are many great applications for photoacoustics, and I am excited to see what the next twenty years will bring. Thanks!

    41:33 Regarding scanning through thick bone. If you'll forgive the simplification, PAT seems like a type of camera which can effectively 3D scan the shape of it's own lens, but in this case the lens being flesh and bone. So can't you use the accumilated scan data from shallower layers as a waveguide/mask to virtually deblur deeper layers?
    i imagine the scanning process being a raster which gradually goes deeper and deeper, layer by layer. The data from each deeper layer goes through a sort of lens-correction filter, effectively put through a software "virtual lens" made up of the accumilated data from the previous layers.
    A bone may blur your image, but you have the capability to scan the exact structure of the bone, thus you have knowledge of the exact nature of the blurring.

    Indeed it is, the field is growing quickly. The conference at our Photonics West Symposium has grown exponentially each year since its introduction. Keep an eye out, we will be publishing an interview with Lihong Wang in the next week or two.

    This is odd. I can hear any other YT video just fine, but this one is so faint that I can barely make out the words, and word endings sometimes have a weird squelch. I went to your website, and the audio is slightly louder, but I still have to have my speakers turned up all the way to hear what is said.

    Can I get the data sets for the PAT

    This looks highly interesting. Unfortunately, something has happened to the sound, making it barely audible and filled with odd clicks.

    Very interesting. I like how the presenter uses "we used math" in the same way one says "we used magic"

    I just swapped out my new speakers for my old, defective speakers. As I suspected, the volume plays just fine on my old, defective speakers.
    I suspect the problem has to do with the channels used in the sound system. Something isn't coming through the difference in design of my new speakers.
