A method and apparatus for dispensing powdered material provides for processing a volume of powdered material to be dispensed so that density of the processed material is modified to substantially uniform density, and further for distributing multiple dosages of the powdered material in a time-efficient, precise manner. A workload analysis unit then determines a target whose data is moved from an HDD to an SSD in units of n_segments. Expected areas for these transmitters are then determined. A medical image belonging to a patient historical exam category and having at least one CAD identified pattern is displayed to a user via the user interface. The enclosure has a screen positioned on the top surface to prevent particles from entering or damaging the leadless sensor. The upright image is formed on the convex surface of a fiber optic imaging taper, which transfers the image to the flat bottom of the taper where it can be viewed through an eyepiece or digitized by a detector array.
