Attorney, Agent or FirmInternational ClassG01V 003/00AbstractMethods and systems obtain three-dimensional images of object morphology using nuclear magnetic resonance imaging. Most preferably, an object is immersed in a volume of imaging fluid. An image is then generated by nuclear magnetic resonance imaging representative of a spatial distribution of the imaging fluid. The three-dimensional image sequences that are obtained thus represent a contoured outline of the image fluid which conforms to the morphology of the object being imaged. These three-dimensional image sequences are then processed to produce a digital array of the object which may be displayed.Field of SearchPARTICLE PRECESSION RESONANCETo obtain localized resonance within a sample Using a nuclear resonance spectrometer system Determine fluid flow rate Measuring anatomical characteristic or force applied to or exerted by body Measuring fluid pressure in body Ultrasonic With therapeutic device Doppler effect (e.g., fetal HR monitoring) Magnetic resonance imaging or spectroscopy Combined with therapeutic or diverse diagnostic device | |
