Abstract: A method for determining positron emission measurement information in the context of positron emission tomography is disclosed. The method includes using a marker substance to carry out a positron emission measurement, in a body area of a subject to be examined, to determine positron emission measurement information, and at the same time, generating images of the body area to be examined by way of a second medical method with a time resolution suitable for determining perfusion and/or diffusion information. The method further includes using the images from the second method to determine perfusion and/or diffusion information for at least a part of the measurement period, and evaluating the positron emission measurement information as a function of the perfusion and/or diffusion information.

Abstract: At least two inputs, at least one output and a clock source for the inputs are provided in a multiplexer. Each input balances an input signal and is coupled to a transistor circuit having two transistors with collectors commonly connected to a power potential. The transistor circuit can be supplied with a first balanced input signal on a first input signal path connected to the base of the first transistor, and with a second balanced input signal on a second input signal path connected to the base of the second transistor. The two balanced input signals are able to have a predetermined switching potential applied to them under the clocking of a driver circuit. In addition, two outgoing signal paths from the emitter of each transistor circuit can be combined to form at least two output signal paths for the at least one output. In this arrangement, the two output signal paths can be connected symmetrically with respect to a reference-ground potential.

Abstract: An ultrasound imaging system has a probe containing a 2-D array of transducer elements and a base unit for the phase-delayed driving of the transducer elements of the array. Transmit pulsers digitally controlled by the base unit are provided for the transducer elements in the probe, and an address decoder is provided for the transmitting state, and a multiplexer for the ultrasonic signals in the receiving state. For the transmitting state, the probe and the base unit are interconnected via digital control lines and, for the receiving state, via a number of signal lines that is reduced by the multiplexer factor of the multiplexer.

Abstract: An apparatus for tuning a balanced-to-ground resonator, the resonator including at least one radio-frequency coil, the radio-frequency coil having an inductance forming a resonant circuit in combination with a capacitor, includes two identical differential capacitors which are mechanically coupled so that their respectively capacitances, during tuning, change in a balanced-to-ground fashion. In this tuning arrangement, the dependency of the frequency error on a change of the load of the resonator is negligibly small, so that a separate step or separate circuitry for undertaking frequency correction is not needed.
