Fig. 4From: Computational fluid dynamics study of intra-arterial chemotherapy for oral cancerClassification of horizontal position of catheter tip. Target arteries are the lingual, facial, and occipital arteries. The catheter tip rotates centering on a point 10 mm away from the tip, and the amount of shift from the centerline of the catheter is a quarter of the diameter of the external carotid artery (ECA). Classification of horizontal position of catheter tip is determined in distal view of the ECA. LA lingual arteryBack to article page
