摘要

The axillary brachial plexus nerve block provides excellent surgical anaesthesia for the elbow, forearm, and hand. By using the ultrasound scanning technique, researchers can identify the location of the axillary artery during the surgery and performclinicalanalysis on physiological effect of nerve blockby measuring the diameter of the axillary artery. However, manual assessment and measurement of the ultrasound imagecan be inaccurate,restricted to intra and inter observer variability and time consuming.The objective of this paper is to propose a precise axillary artery diameter measurement method by using a series combination of image processing techniques. The imagesare smoothed by Weiner, Frost and followed by anisotropic diffusion filters. Manual thresholding is applied to the image and followed by level set segmentation. The precision of the artery measurement before and after the image processing techniques is gauged by evaluating the standard deviation of the diameter parameters.The findings show that the measured diameter of processed image has smaller standard deviation of 0.019 mm as compared with original image of 0.045 mm.The studyconcludes that the processed image can clearly indicate the location of the axillary artery.
