Abstract: Systems, apparatuses, and methods provide for matching unassigned patient data to individual patients. For example, such operations include collecting data from a plurality of data sources in a plurality of formats. Data information Machine time stamps are converted from collected data to universal time zone data time stamps. A same patient is matched to the collected data based on the universal time zone data time stamp. A quality estimate of the match is quantified. The match and quality estimate of the match are transferred to a user interface.

Abstract: The invention provides for a magnetic resonance system (100) comprising a magnet (104) for generating a main magnetic field within the measurement zone and a magnetic field gradient system (110, 112) for generating a gradient magnetic field within the measurement zone in at least one direction by supplying current to a set of magnetic gradient coils (112) for each of the at least one direction. Instructions cause a a processor (130) controlling the magnetic resonance system, wherein execution of the machine executable instructions causes the processor to acquire (200) the magnetic resonance data by controlling the magnetic resonance system with pulse sequence commands. The pulse sequence commands (140) cause the magnetic resonance system to acquire the magnetic resonance data according to a magnetic resonance fingerprinting technique. The pulse sequence commands specify a train (500) of pulse sequence repetitions (502, 504), each with a fixed repetition time (302). Each repetition comprises either a radio frequency pulse (310) chosen from a distribution of radio frequency pulses or a sampling event (404) occurring at a fixed delay (316) from the start of the pulse sequence repetition. The pulse sequence commands specify the application of gradient (308) magnetic fields in the at least one direction by controlling the supplied current to the set of gradient coils. Each of the set of magnetic gradient coils the integral of current supplied is a constant for each fixed repetition time. The instructions further cause the processor to calculate (202) the abundance of each of a set of predetermined substances by comparing the magnetic resonance data with a magnetic resonance fingerprinting dictionary (144).

Abstract: A magnetic field z-gradient coil is manufactured by inserting elements (38) into openings (36) on an outside of an insulating carrier (32), wrapping an electrical conductor turn (34) around the outside of the insulating carrier with one side of the wrapped electrical conductor alongside elements inserted into openings on the outside of the insulating carrier, removing the elements alongside the one side of the wrapped electrical conductor from the openings, and repeating to wrap conductor turns of a z-gradient coil (20) around the electrically insulating carrier. A transverse magnetic field gradient coil is manufactured by laying electrical conductor (44) onto a mold (50) with a keying feature (46, 46a) extending along the conductor engaging a mating keying feature (52, 52a) of the mold that defines a winding pattern (56), attaching an insulating back plate (58) to the resulting coil section opposite from the mold, and removing the mold.
