Abstract:
1. A method for finding the location, P′, and size, r′, of a pulmonary nodule in a high-resolution three-dimensional computed tomography (CT) image, the method comprising: (a) selecting a set of initial processing parameters including an initial location, P (b) computing an initial new location P (c) incrementally increasing size, r (d) computing a new location P (e) computing a size metric with a three-dimensional density-based sizing template function in a fourth computer process performed by a computing device; (f) repeating steps (c) through (e) until the size metric is less than the target value; (g) returning the location, P′, and the size, r′, from the previous iteration of steps (c) through (e) in a fifth computer process performed by a computing device.
