impact in the human side the photo acoustic tomography has been commercialized by several companies now I personally work with two of them so for preclinical imaging it has been you know established so there are products available they are being sold for a human imaging it's not there yet so I was not allowed to mention the name of the company which has licensed our IP for human imaging but so we're very happy that this is moving forward so it's going to take some time eventually I'd like to see this is this as a daily used at all
