Appreciate your response. Neither of them have been very helpful. I am not looking for what a specific person may have asked as a question. I was interested in what Dr Starr had to say. What was his view of histotripsy and when it would be best used. What the criteria might be that he is using. Since I registered early, I still do not know why I could not connect. There were some others that also had problems connecting last night. Thanks again.
