Magnetic resonance method, apparatus and radiofrequency coil for acquiring magnetic resonance data of at least one tooth

摘要

In a magnetic resonance method and apparatus for the acquisition of measurement data of at least one tooth of an examination subject, a pulse sequence is employed that has an echo time TE of less than 0.5 milliseconds, and spatial coding of the acquired measurement data takes place in only two spatial directions. Projection image data are reconstructed from the acquired measurement data. A coil for a magnetic resonance tomography system, which coil is dedicated to dental imaging, has at least one coil element, and each coil element of the coil has an individual acquisition volume that encompasses at least one tooth.

主权项

1. A method to acquire magnetic resonance data from at least one tooth of an examination subject comprising:
operating a magnetic resonance data acquisition unit with a data acquisition sequence to acquire magnetic resonance data from at least one tooth of an examination subject; using, as said pulse sequence, a pulse sequence having an echo time of less than 0.5 milliseconds and that spatially codes the acquired measurement data from said at least one tooth in only two spatial directions; providing the acquired magnetic resonance data to a processor and, in said processor, generating projection image data representing a two-dimensional projection of said at least one tooth from said magnetic resonance data that are spatially coded in only two spatial directions; and making said projection image data available in electronic form at an output of said processor, as a data file.
