Fig. 5: Tracing intestinal motility by BioUCT in vivo.
From: Biodegradable ultrasound contrast tape for tracing intestinal motility
a Implanting the BioUCT on the small intestine of a live pig. b Results of blood count (e) and blood chemistry (f) tests within 10 weeks after the implantation of BioUCT in a live pig. c Image of a live pig’s small intestine before and after the implantation of the BioUCT. The scale bar is 10 mm. d B-mode ultrasound image of the pig’s small intestine before the implantation (left), compared to images at day 1 (middle) and day 15 (right) after the implantation of the BioUCT. The scale bar is 10 mm. e The BioUCT enhanced the brightness of the small intestine after the implantation; n  =  3 independent tests. f B-mode ultrasound imaging with a time interval of 15 s. The scale bar is 20 mm. g The placement of the M-mode scanning line. The scale bar is 10 mm. h Time-domain waveform of echoes reflected by the BioUCT. i M-mode ultrasound imaging of the BioUCT for tracing intestinal motility. The amplitude of the intestinal motility increases from 3.13 mm to 7.59 mm after taking Motilium.
