— Ultrasound-based imaging technique becomes a promising way to acquire normal or abnormal condition of most human organ since it provides several advantages compared to other imaging modalities. This study used ultrasound imaging modality to acquire colon images and determine the wall-thickness of the colon. Wall thickness is important parameters for evaluating the condition of colon, especially for the people with irritable bowel condition. Three different parts of colon were scanned during this study; ascending part, transverse part and descending part. Manual measurement of cross-sectional area and wall-thickness of colon was done by the radiologist during image acquisition process. In order to obtain clear image and ensure measurement accuracy, several steps of image processing; pre-processing, filtering, cropping, and textural segmenting were done. The results showed that the result from the measurement after image processing relatively closed to that of the manual, with the value of standard deviation of 0.02. The output from this study can be used for further study in assessment of various colon diseases that based on the cross-sectional area and the wall thickness of the colon like inflammatory bowel disease (IBD).
