摘要： A magnetic resonance imaging system connectable to a respiration monitor configured to provide an output signal whose level represents a respiration state. A prospective acquisition scheme for acquiring magnetic resonance images at each of a set of selected respiration states is provided, the triggering on the selected respiration states being based on predetermined threshold output signal levels of the respiration monitoring means, Respiration states at which magnetic resonance images were actually acquired, are compared with the selected respiration states according to the prospective acquisition scheme and predetermined ranges of tolerance of the selected respiration states, The prospective acquisition scheme is modified, if one of the actual respiration states lies outside the predetermined range of tolerance of the selected respiration state, and magnetic resonance imaging acquisition is executed pursuant to the modified prospective acquisition scheme.

摘要： The invention provides for a method of operating a magnetic resonance imaging system. The method comprises the steps of: acquiring (200) first magnetic resonance data (142) by controlling the magnetic resonance imaging system with pulse sequence instructions (140), reconstructing (202) one or more first image (144) from the first magnetic resonance data, and assigning (204) the one or more first image to a first memory group of a set of memory groups (300). The method further comprises repeatedly performing the following steps: acquiring (206) sequential magnetic resonance data (148) by controlling the magnetic resonance imaging system with the pulse sequence instructions, reconstructing (208) one or more sequential image (150) from the sequential magnetic resonance data, computing (210) a distance measure (152) between the one or more sequential image and each of the set of memory groups, assigning (214) the one or more sequential images to a chosen memory group if the distance measure between the chosen group and the one or more sequential images is within a predetermined range, creating (216) a subsequent memory group (304) in the memory if the one or more sequential images is not assigned to the chosen memory group, and assigning (218) the one or more sequential image to the subsequent memory group if the subsequent memory group is created.

摘要： A medical apparatus (1100) comprising a magnetic resonance imaging system and an interventional device (300) comprising a shaft (302, 1014, 1120). The medical apparatus further comprises a toroidal magnetic resonance fiducial marker (306, 600, 800, 900, 1000, 1122) attached to the shaft. The shaft passes through a center point (610, 810, 908, 1006) of the fiducial marker. The medical apparatus further comprises machine executable instructions (1150, 1152, 1154, 1156, 1158) for execution by a processor. The instructions cause the processor to acquire (100, 200) magnetic resonance data, to reconstruct (102, 202) a magnetic resonance image (1142), and to receive (104, 204) the selection of a target volume (1118, 1144, 1168). The instructions further cause the processor to repeatedly: acquire (106, 206) magnetic resonance location data (1146) from the fiducial marker and render (108, 212) a view (1148, 1162) indicating the position of the shaft relative to the target zone.
