A method whereby motion can be detected in real time during the acquisition of MRI data. This enables the implementation of several algorithms to reduce or eliminate this motion from an image as it is being acquired. The method is an extension of the acceptance/rejection method algorithm called the ...

John S Wenstrand, Todd S Sachs: Resolution and image quality improvements for small image sensors. Agilent Technologies, January 3, 2006: US06983080 (12 worldwide citation)

An image having higher resolution and/or better color is generated from multiple images of a subject taken by a handheld imaging device. The motion of the device, even when a user holds the device steady, gives the images perspectives that differ by an amount ranging from a fraction of a pixel to a ...
