摘要： The invention relates to means for determining the spatial configuration of a biological body (P) on a surface, particularly on the surface of a patient support (150). One embodiment of these means is a sensor system (110) that can be applied to a patient support (150) and that comprises a plurality of sensor units (111), wherein each of these sensor units (111) has an adjacent sensitive zone (112) in which the presence of a biological body (P) induces a detection signal. The sensor unit may particularly comprise a microwave coil (111).

摘要： Presented are concepts for matching a subject to one or more resources or workflow steps. Once such concept comprises obtaining data associated with a subject, the data comprising, for each of a plurality of parameters, a parameter value relating to the subject. A plurality of data groups for characterising the subject is then generated and a classification process is applied to each data group so as to generate a classification result for each data group. The subject is then matched to one or more resources or workflow steps based on the classification results.

摘要： The invention provides for a medical instrument (100) comprising a magnetic resonance imaging system (104) with an imaging zone (132) and a radiotherapy system (102) configured for irradiating a target zone (138) with a radiation beam (142). The target zone is within the imaging zone. The magnetic resonance imaging system comprises a main magnet (112) with a bore (122) for receiving a subject (136), wherein the imaging zone is within the bore, wherein the bore connects a first entrance (154) and a second entrance (156), wherein the radiation beam defines at least one path through the bore. The magnetic resonance imaging system further comprises a magnetic gradient coil (124) within the bore. The magnetic resonance imaging system further comprises a tubular body coil (129) within the bore. The tubular body coil is surrounded by the magnetic gradient coil. The magnetic resonance imaging system further comprises an RF screen (144) between the magnetic gradient coil and the tubular body coil. The magnetic resonance imaging system further comprises an RF system (130) for providing RF power to the tubular body coil. The magnetic resonance imaging system further comprises an RF feed circuit (146) positioned between the tubular body coil and the RF screen. The RF feed circuit is located within the bore. The RF feed circuit comprises one or more RF power feeds (148, 148') adjacent to the first entrance. The RF power feeds are configured for connecting to the RF system. The tubular body coil further comprises one or more pairs of matching networks (150, 150') for coupling the one or more RF power feeds to the tubular body coil. Each of the one or more pairs of matching networks comprises a first matching network located between the first entrance and the at least one path and a second matching network located between the second entrance and the at least one path. The RF feed circuit comprises at least one transmission line (152). The at least one transmission line is formed from a laminated circuit board (600, 700). Each of the one or more pairs of matching networks is connected by one of the at least one transmission line.

摘要： The present invention provides an exam room shielding (10) for electromagnetically shielding a magnetic resonance imaging system (2), the exam room shielding (10) comprising 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), wherein both longitudinal ends (13) of the tubular shielding device (12) are circumferentially connected to openings (14) of the side walls (11), and the side walls (11) of the shielding (10) 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).The present invention further provides a magnetic resonance imaging system (2) comprising an exam room (1), wherein the exam room (1) has the above exam room shielding (10). The present invention also provides a system (6) comprising the above magnetic resonance imaging system (2) and an additional treatment or diagnosis device (7) 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.
