PyDBS: an automated image processing workflow for deep brain stimulation surgery.

abstract：PURPOSE:Breast masses exhibit variability in margins, shapes, and dimensions, so their detection is a difficult task in mammographic computer-aided diagnosis. Mass detection is usually a two-step procedure: mass identification and false-positive reduction. A new method to automatically detect mass lesions in mammograph...
