A brain-computer interface is a direct communication pathway between a human brain and an external device. It allows users to act on their environment by using only brain activity, without using peripheral nerves and muscles. The paralyzed person controls the brain-computer interface device by performing mental activities which are associated with actions that are dependent on the BCI application. The device is used to acquire the brain signals. Signal processing techniques are then applied to the acquired signals for feature extraction. The classification stage serves as a means of...

Breast cancer is the uncontrolled growth of abnormal cells that start in the breast. It was and still the most common cancer diagnosed in women worldwide. In this book, Computer-aided detection (CADe) and Computer-aided diagnosis (CADx) systems are developed and applied to the standard MIAS and DDSM databases to distinguish between the different breast tissues. In both CAD systems, regions of interest (ROIs) are selected then a set of 422 features are extracted and normalized. The features selection is performed using statistical methods such as t-test, KS-test and W-test and other methods by...

Computed Tomography(CT)is a widely used imaging technique in medical diagnosis. It relies on collecting data about an object from multiple views representing its projections and subsequently using these data to construct an image. Among the latest advances in CT is the utilization of cone-beam geometry of x-ray projections is used instead of the usual planar fan beam.This technique is called Cone Beam CT(CBCT)and promises even faster yet safer 3D imaging compared to previous CT technologies. Present reconstruction methods are classified into two main categories, namely;analytical and...
