Abstract
A magnetic resonance apparatus has a positioning unit and a patient bed. The positioning unit can store a number of positions of the patient bed and can automatically position in an imaging volume the associated examination regions established by a marking unit in a diagnostic data acquisition procedure predetermined by a measurement control unit. The positioning unit can detect dimensions of a patient by evaluation of the number of positions of the patient bed and transfer these dimensions to a monitoring module. The monitoring module adapts the RF transmitting power to the patient according to the dimensions.
Claims5
A magnetic resonance apparatus comprising:
- a movable patient bed adapted to receive an examination subject thereon;
- a positioning unit connected to the patient bed for detecting respective positions of the patient bed and for changing the position of the patient bed;
- a marking unit adapted to establish different examination regions of the examination subject;
- said marking unit being connected to said positioning unit and supplying information to said positioning unit regarding the different established examination regions, and said positioning unit detecting at least one dimension of the examination subject by evaluating said information;
- said positioning unit associating respective positions of the patient bed with the respective examination regions established by the marking unit, and storing at least two different positions of said patient bed to allow substantially uninterrupted, successive examination of the examination regions, respectively associated with the stored positions, by successively automatically moving the patient bed between said at least two different positions stored by said positioning unit.
