A surgical method and workflow to improve the efficiency of a surgical procedure by intraoperatively acquiring a digital radiographic image, processing the digital radiographic image, and using information based on the radiographic image to make adjustments during the surgical procedure. The reactivity of the foam forming system can be controlled by the addition of an autocatalytic polyol containing a tertiary amine where the amount of autocatalytic polyol comprises less than 5 percent by weight of the total polyol. By practicing the pitching motion, the relative position of the indicator bands will confirm and teach proper pitching arm and hand position through the multiple underhand pitching sequence of softball pitching action. Additionally, two exemplary systems describe the implementations of two embodiments of the presented methods. , an improved digestion performance in vitro, an improved activity at a pH in the neutral range, an improved stability at low pH, and are stable against protease-degradation, andor are stable in the presence of pepsin and bile salts.
