(boundary between the) white and dark structures/areas Explanation: I couldn't find any example of "valley". That's really a separate question. I can't visualize how it would appear. It's the point at which one stops and the other begins, so it's more like a boundary; even if it's fuzzy, it would contain properties of both. "White and dark structures' is pretty common: the former is hyperechoic and the latter is hypoechoic. Hypoechoic: dark structures/areas on the screen, e.g. vessels, cysts...

For example, there may be multiple structures that have different intensity characteristics, like in the central area of the lungs where various anatomical structures exist. Even when only one anatomical structure is present, its intensity may vary due to the partial volume effect. This occurs frequently with small vessels. In either case, there will be no distinct valley in the histogram. Instead, we adaptively set the threshold for target structure segmentation by finding the curvature extrema of the local histogram (in step 316c). Noticing that peaks in the curvature plot correspond to sharp drops in the histogram, and reflect abrupt changes in intensity distribution, the threshold can be set as the intensity value where the sharpest change occurs. -------------------------------------------------- Note added at 2 hrs (2009-10-27 10:28:57 GMT) -------------------------------------------------- "valley" IS used on sites re CT scans of the lungs, from my findings:) -------------------------------------------------- Note added at 2 hrs (2009-10-27 10:31:21 GMT) -------------------------------------------------- # Subtraction technique for computerized detection of small lung ...
