Abstract: A system with integrated tracking includes a procedure-specific hardware component (112 or 116) disposed at or near a region of interest. A field generator (114) is configured to generate a field with a field of view covering the region of interest. A mounting device (115) is connected to the field generator and is coupled to the procedure-specific hardware. The field generator is fixedly positioned by the mounting device to permit workflow access to the region of interest without interfering with the field generator and to provide a known position of the field generator relative to the region of interest. A tracking device (110) is configured to be inserted in or near the region of interest to be tracked within the field of view of the field generator to generate tracking data.

Abstract: 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.

Abstract: The invention provides for a medical instrument (200, 300, 400, 500, 600, 700) comprising a magnetic resonance imaging system (204) operable for acquiring magnetic resonance data (266) from a subject (236) within an imaging zone (232) and an external beam radiotherapy system (202) operable for irradiating a target zone (238) within the imaging zone. The medical instrument further has a radiation beam generation system (208, 302, 302′, 302″) operable for generating a radiation beam (242, 304, 304′, 304″) and a radiation beam detection system (243, 502, 502′) operable for acquiring radiation beam detection data (270) descriptive of the radiation beam. Instructions cause a processor (248) controlling the instrument to receive (100) planning data (260) descriptive of a spatially dependent radiation dose and generate (102) external beam radiotherapy control commands (264) using the radiation dose. The instructions causes the processor to repeatedly: control (106) the external beam radiotherapy system to irradiate the target zone using the external beam radiotherapy system control commands; generate (108) the radiation beams using the radiation beam generation system; measure (110) the radiation beam detection data using the radiation beam detection system; acquire (112) the magnetic resonance imaging data using the magnetic resonance imaging system, generate (114) a magnetic resonance image (268) using the magnetic resonance image data, determine (116) a registration (274) of the magnetic resonance image to the radiation beam detection data; calculate (118) a mapping (276) using the registration; and modify the external beam radiotherapy system control commands using the mapping.

Abstract: An exam room shielding (10) for electromagnetically shielding a magnetic resonance imaging system (2) includes: a ceiling, a floor, side walls (11) interconnecting the ceiling and the floor, and a tubular shielding device (12), which is arranged to surround an examination tube (3) of the magnetic resonance imaging system (2). Both longitudinal ends (13) of the tubular shielding device (12) are circumferentially connected to openings (14)of the side walls (11) which form the outline of an U-shaped room (15) with the longitudinal ends (13) of the tubular shielding device (12) interconnecting the lateral flanks (16) of the U-shaped room (15). A magnetic resonance imaging system (2) includes an exam room (1), with the above exam room shielding (10). An additional treatment or diagnosis device (7) can be located at an outer circumference of the tubular shielding device (12). This separates the space inside the exam room into a compartment free of RF noise, i.e. the space surrounded by the exam room shielding, for MR scanning, and a compartment outside the shielding, in which an operator can move for operating the MR imaging system and/or preparing a person for a MR scan.
