摘要： Timing in a medical imaging system. The system comprises a magnetic resonance imaging (MRI) subsystem and a non-MRI subsystem. Operation of the non-MRI subsystem involves a timing signal within a radio frequency (RF) cabin of the MRI subsystem. Basing each non-MRI subsystem timing signal on a time base common between the MRI subsystem and the non-MRI subsystem. The non-MRI subsystem can be a medical imaging subsystem. The non-MRI medical imaging subsystem can be a positron emission tomography (PET) subsystem. Each non-MRI subsystem timing signal that based on the common time base can be created using the same model of equipment used for creating timing signals in the MRI subsystem. At least one stage of the non-MRI subsystem timing signal based on the common time base can be created using the same equipment used for creating timing signals in the MRI subsystem.

摘要： The invention relates to calibration phantoms used in connection with medical imaging devices such as PET, MR, etc., and particularly in connection with hybrid systems such as MR/PET systems. In some cases, the phantoms have distinguishable, machine-readable identification features that allow the imaging system to identify them automatically, without operator intervention. In other cases, even where the phantoms do not have such distinguishable, machine-readable identification features, if the imaging system is appropriately configured with cameras and/or appropriate image analysis software, the imaging system can still identify the phantoms automatically.

摘要： PET signals are amplified in a hybrid PET/MR system. An amplifier structure is provided for operation in the magnetic field of the MR magnets. By filtering to remove signals at the MR frequency (e.g., about 123 MHz) as part of the amplification circuit, the amplification circuit may be positioned within the RF cabin, within the magnetic field, and even within a same housing as the MR magnets. MR interference may be reduced by staged amplification. The filtering may be bi-directional, such as using parallel and series traps. Digitization of the PET signals may be provided within the magnetic field with no or little interference with MR operation.

摘要： A partitioned pipeline read-out circuit architecture eliminates real-time constraints from off-chip read-out control electronics in a solid-state radiation detector system, so that an efficient decoupled architecture is possible. The front-end electronics includes a multi-channel ASIC with independently triggered charge sensitive pre-amplifiers, shaper circuits, and switched sample-and-hold capacitor circuits for each photodiode or pixel of the detector module. With this structure, individual photodiodes of the photodetector array can detect and store scintillation events independently and randomly. The ASIC is interfaced to an external successive approximation A/D converter for conversion and subsequent input to a data processing apparatus.
