Since the incidence of cerebral microbleeds (CMBs) have
come to attention as a potential biomarker of
cerebrovascular disease and dementia, a computer-aided
detection scheme to improve screening is required. In
this work, a novel approach of CMB detection in SWIs is
presented and compared to visual rating. The proposed
method (1) identifies potential CMB candidates with
their corresponding bounding boxes using a multi-scale
Gaussian technique, (2) extracts a set of robust 3D
Radon- and Hessian-based shape descriptors within the
bounding boxes, as well as 2D Radon features computed on
intensity-projection images, and (3) incorporates a
cascade of random forests classifiers to reduce false
detection rates.
