International Classification:

F27B 926

US Classification:

432241

Abstract:

The present invention relates to kiln car refractory furniture. In combination, (a) a kiln car having chassis that carries a platform; (b) a curb of a row of a plurality of hollow load-bearing refractory modules aligned along the periphery of the platform of the kiln car; and (c) an insulating amount of refractory insulation dispersed between the modules and laying over the platform of the kiln car. Each load-bearing hollow refractory module further comprises: (i) a hollow body formed of a refractory material having spaced walls and a top wall defining a hollow insulating space; (ii) at least one socket means for supporting a refractory post where the post in turn supports a load of refractory ware; (iii) a securing means for supporting the socket means spaced apart from the platform of the kiln car; and (iv) surfaces on the body adapted to interlock with surfaces on another abutting module. The modules may have an open bottom for passing refractory insulating material therethrough so that an insulating amount of refractory insulating material may be dispersed inside the hollow insulating space. The kiln car furniture modules may also have surfaces adapted to overlap with corresponding surfaces on an interior side wall of a tunnel kiln.

Abstract:

A method for magnetic resonance fingerprinting with out-of-view artifact suppression includes acquiring MRF data from a region of interest in a subject. The MRF data is acquired using a non-Cartesian, variable density sampling trajectory. The MRF data includes data from within a desired field-of-view and data from outside the desired field-of-view. The method also includes generating a set of coil images based on the MRF data with a field-of-view larger than the desired field-of-view, determining a noise covariance based on the MRF data from outside the desired field-of-view, generating a coil combined image using an adaptive coil combination determined based on the noise covariance, applying the adaptive coil combination to the MRF data to grid each frame of the MRF data and generate MRF data with out-of-view artifact suppression. The method also includes identifying at least one property of the MRF data and generating a report.

International Classification:

G01R 33/50
G01R 33/54

Abstract:

A method for quantifying T1, T2 and resonance frequency simultaneously using magnetic resonance fingerprinting (MRF) includes accessing an MRF dictionary using a magnetic resonance imaging (MRI) system. The MRF dictionary is generated by simulating signal evolutions that include associated off-resonance effects for each signal evolution. The method further includes acquiring MRF data from a region of interest in a subject using the MRI system and a MRF pulse sequence having a plurality of radio frequency (RF) excitations and a readout associated with each RF excitation. Each readout includes a plurality of segments and each segment is used to generate a time frame. The method also include comparing the MRF data to the MRF dictionary to identify a plurality of parameters including T1, T2 and resonance frequency for the MRF data and generating a report indicating the at least one of the plurality of parameters of the MRF data.

Abstract:

Example embodiments associated with characterizing a sample using NMR fingerprinting are described. One example NMR apparatus includes an NMR logic that repetitively and variably samples a (k, t, E) space associated with an object to acquire a set of NMR signals that are associated with different points in the (k, t, E) space. Sampling is performed with t and/or E varying in a non-constant way. The NMR apparatus may also include a signal logic that produces an NMR signal evolution from the NMR signals and a characterization logic that characterizes a tissue in the object as a result of comparing acquired signals to reference signals. Example embodiments facilitate analyzing voxels having multiple compartments that may experience magnetic exchange. The compartments may be, for example, an intracellular volume and an extracellular volume in a tissue that experiences magnetic exchange due to the movement of water between the volumes.
