Universal Lesion Detection (ULD) in computed tomography plays an essential role computer-aided diagnosis. Promising ULD results have been reported by multi-slice-input detection approaches which model 3D context from multiple adjacent CT slices, but such methods still experience difficulty obtaining a global representation among different slices and within each individual slice since they only ...

Recently, the linear-quadratic equation has been used to construct the dose-response relationships of ionizing radiation. The radiobiological theory on which this relationship is based indicates that at low doses, the risk of a biological lesion being formed should depend linearly on dose if a single event is required or quadratically on dose if two events are required. The same approach has al...

Background Computer Aided Diagnosis (CAD) systems have been developing in the last years with aim of helping diagnosis and monitoring several diseases. We present a novel CAD system based on hybrid Watershed-Clustering algorithm for detection lesions Multiple Sclerosis. Methods Magnetic Resonance Imaging scans (FLAIR sequences without gadolinium) 20 patients affected by Sclerosis hyperintense w...
