Fig. 3From: Void characteristics and tortuosity of calcium silicate-based cements for regenerative endodontics: a micro-computed tomography analysisSchematic of the A-start algorithm. AC(t) denotes the actual distance between the starting point and a temporary point, while HC(t) is the distance between the temporary and end points at iteration process t. The total cost TC(t) is computed by adding the two functionsBack to article page
