Gastric assessment by images processing of ultrasound in LabVIEW platform: preliminary results

Abstract

Nowadays, the gold technique in gastric evaluations still is scintigraphy in spite of ionization radiation dose per patient undergoing this procedure. Gastro images with ultrasound technique are controversial, because the stomach is a hollow cavity filled with gas in basal conditions or in fast state. Fortunately, a stomach with food is recommended in gastric motility and gastric emptying assessment. So, a lack of air in stomach contributes in this kind of study and in recordings of excellent images by ultrasound. In this study, a digital image processing of gastric ultrasound is presented. Whole automated routine and implemented filters are described in order to use this procedure in gastric peristalsis and gastric emptying evaluations. Ten volunteers were recruited and required to attend the measurements about dominant frequency, with values of at least 3 cpm. Although the behavior stomach activity is observed in dynamic graph, an analysis in frequency space is performed.
