Abstract: A multi-channel switching system (100) for an MRI gradient coil system is characterized in that the number of channels controlled by the power amplifiers is smaller than the number of switches and the number of channels controlled by the power amplifiers is smaller than the number of coil elements in the coil system. Current in each of the coil elements can be switched to flow in either a positive or negative direction or to bypass the respective coil element and power to the switch elements is delivered via a smaller amount of power lines using a power distribution system providing floating power to each of the switches. This allows to electrically connect matrix coil elements dynamically within a pulse sequence to generate dynamically switched magnetic field profiles and therefore reduce the number of gradient power amplifiers, gradient cables and power supplies needed.

Abstract: A receiving device and a method for operating a receiving device are provided in which a signal is divided into two separate signal parts. The two signal parts are demodulated simultaneously and, from the demodulated signals, the difference is formed. After the formation of the difference, an information item is obtained from the difference signal and compared with a predetermined information item. In the case of correspondence of the obtained information and the compared information, a wake-up signal is generated.

Abstract: In a method to associate k-space lines with echo trains of raw magnetic resonance data, parallel k-space lines orthogonally intersect a plane at respective intersection points. Each echo train has a trajectory length, and the k-space lines are associated with the echo trains such that a sum of trajectory lengths of all echo trains is minimal. The trajectory length TL of an echo train is defined by TL = ? i = 1 L - 1 ? ? P i ? P i + 1 _ wherein L is a sequence of k-space lines, Pi is an intersection point of the i-th k-space line of the echo train with the plane; and PiPi+1 is the length of the path from the i-th intersection point to the (i+1)-th intersection point.

Abstract: A method of producing a replicate or derivative of an array of molecules, the array having a spatial arrangement of separate samples of molecules, includes creating, for each sample, at least one spatially limited effective area which is separate from the effective areas of the other samples, a surface, provided with a binding adapter or binding properties, of a carrier bordering on the effective areas. The molecules are amplified by means of amplifying agents in the effective areas for creating replicates or derivatives of the samples. The replicates or derivatives of the samples are bound to the carrier by means of the binding adapter or the binding properties, so that a spatial arrangement of the replicates or derivatives of the samples on the carrier corresponds to the spatial arrangement of the samples in the array. The carrier having the copies of the samples is removed from the array.

Abstract: A method is presented for accelerating magnetic resonance imaging. In 3D MRI, the k-space in the phase encoding plane is divided into two symmetric parts and three asymmetric parts. Different sampling densities are applied in different parts. Images are reconstructed by iteratively minimizing a cost function when random sampling is applied in each part. A phase constraint term is added into the cost function to improve the quality of the reconstruction by exploiting the conjugate symmetry of k-space.
