Stationary anterior phased array coil for simultaneous PET-MR imaging

摘要

A PET-MR apparatus includes an MR imaging system for acquiring MR signals and a PET system for acquiring PET emissions of the patient. The PET-MR apparatus also includes an anterior surface coil configured to receive MR signals from a volume-of-interest of the patient in the bore and resulting from the emitted RF pulse sequence and a coil positioning structure mounted to the PET-MR apparatus and configured to receive the anterior surface coil thereon and position the anterior surface coil proximate to the volume-of-interest of the patient without coming in contact with the patient, with the coil positioning structure being configured to provide both a vertical adjustment of the anterior surface coil relative to a coronal plane of the patient and an angular adjustment of the anterior surface coil relative to the coronal plane of the patient.

1. A PET-MR apparatus comprising:
a magnetic resonance (MR) imaging system having a plurality of gradient coils positioned about a bore of a magnet, and an RF coil assembly coupled to a pulse generator to emit an RF pulse sequence for use in acquiring MR signals from a patient in the bore; a positron emission tomography (PET) system having a detector array positioned around a PET tube encircling the bore, with the detector array being controlled to acquire PET emissions of the patient; an anterior surface coil configured to receive MR signals from a volume-of-interest of the patient in the bore and resulting from the emitted RF pulse sequence; and a coil positioning structure mounted to the PET-MR apparatus and configured to receive the anterior surface coil thereon and position the anterior surface coil proximate to the volume-of-interest of the patient without coming in contact with the patient, the coil positioning structure being configured to provide both a vertical adjustment of the anterior surface coil relative to a coronal plane of the patient and an angular adjustment of the anterior surface coil relative to the coronal plane of the patient.
