Auto calibration of a cone-beam-CT.
PURPOSE This paper introduces a novel autocalibration method for cone-beam-CTs (CBCT) or flat-panel CTs, assuming a perfect rotation. The method is based on ellipse-fitting. Autocalibration refers to accurate recovery of the geometric alignment of a CBCT device from projection images alone, without any manual measurements. METHODS The authors use test objects containing small arbitrarily posi...

There are many points of contact between film and psychology. Across the decades, scholars have made film the object of psychological analysis,1 while psychiatrists and psychologists pervade cinema and television, from Alfred Kinsey to Hannibal Lecter.2 Early documentary films addressing psychology include Glub Glub and the Monkeys (Robert Allen, 1975), about the research of Robert and Joan Hin...
متن کاملFilming chimpanzee gestures.
The Sonso community of chimpanzees has its own reality television show. However, the show isn’t on any cable network; it’s for the benefit of science. By capturing the chimps’ daily lives and interaction on camera, researchers hope to understand how their gestures evolved and find clues to the origins of human language. Catherine Hobaiter, a field primatologist from St. Andrews University, Scot...
متن کاملStandard edge detection algorithms versus conventional auto-contouring used for a three-dimensional rigid CT-CT matching
Background: To reduce uncertainties of patient positioning, the Computerized Tomography (CT) images acquired at the treatment planning time can be compared with those images obtained during radiation dose delivery. This can be followed during dose delivery procedure as Image Guided radiotherapy (IGRT) to verify the prescribed radiation dose delivery to the target as well as to monitor ...

Vesicular release of neurotransmitter is the universal output signal of neurons in the brain. It is generally believed that fast transmitter release is restricted to nerve terminals that contact postsynaptic cells in the gray matter. Here we show in the rat brain that the neurotransmitter glutamate is also released at discrete sites along axons in white matter in the absence of neurons and nerv...
