Figure 2. Porcine in-vivo validation trial.
(a) Position of the novel laparoscopic device and standard electrode platform (E32) on the anterior serosal surface of the porcine stomach. The devices were separated by a 45 mm gap. (b) A typical 80 s segment of slow wave recordings from the positions shown in (a). The top three channels are from the laparoscopic device and the bottom three channels are from the standard platform. A time lag of approximately 6.5 s is noted in the detection of slow wave events between the two devices.
