摘要： An imaging subject (16) is disposed in an examination region (12) for examination. A cover (18) is disposed around the examination region (12). Magnetic field gradient coils (30) impose selected magnetic field gradients on a main magnetic field (B0) within the examination region (12). A radio frequency (RF) coil (36) generates radio frequency excitation pulses in the examination region (12), the radio frequency coil (36) including a plurality of coil elements (381, 382, 383) disposed on the cover (18) distally from the examination region (12). A radio frequency (RF) screen (40) associated with the coil elements (381, 382, 383) shields the coil elements (381, 382, 383) and is disposed about the gradient coils (30) such that the coil elements (381, 382, 383) are mechanically decoupled from the RF screen (40) and substantially acoustically isolated from the RF screen (40) and gradient coils (30).

摘要： The invention relates to magnetic resonance imaging and offers a way to provide even the non expert user with full control of a magnetic resonance imager. The invention achieves this by offering a user interface in is arranged to assign values to at least one attribute used to influence the visual presentation of an acquired magnetic resonance image and in which the values of the at least one attribute are arranged to be chosen from information indicating the effects of their assignment on the content of the visually presented acquired magnetic resonance image.

摘要： A magnetic resonance imaging (MRI) system includes a gradient coil system. The gradient coil system comprises an inner coil configuration (1,2,3) and an outer coil configuration (4,5,6) positioned substantially coaxially with said inner coil configuration (1,2,3). Both coil configurations are attached to a tubular body (7) located between said two coil configurations (1,2,3,4,5,6) and extend substantially coaxially with both of the coil configurations. The tubular body (7) comprises stainless steel rods (10) positioned substantially in an axial direction.

摘要： A diagnostic imaging system (1), in particular a magnetic resonance imaging system. The diagnostic imaging system comprises control system (2) to control the execution of operational items by the diagnostic imaging system. A user interface (3) is coupled to the control system, the user interface including a scheduler module which forms an ordered selection of operational items. The operational items are executed on the basis of the ordered selection. The ordered selection concerns the order, timing and conditions to be fulfilled to execute the operational items. Notably, in an magnetic resonance imaging system the actual acquisition concerns the execution of acquisition pulse sequences to receive magnetic resonance signals which is carried out for the planned geometry, the preferred embodiment comprises a patient support that can be moved among various positions which is used in a multi-station examination.
