Problems solved by technology

Such sharp seams can cause irritation at the patient's sensitive skin and reduce patient comfort
In addition, the deformation of the local coil when adapted to the patient's body can lead to warping and crease formation, especially in the region of such joint lines
This may cause detachment of the composite material in the long term and hinder positioning of the local coil at the patient

Embodiment Construction

[0077] exist figure 1 An embodiment of a magnetic resonance system with a magnetic resonance system 10 , a local coil 26 and electrical connecting lines 27 is schematically shown in FIG. The magnetic resonance system 10 includes a magnet unit 11 having, for example, a permanent magnet, an electromagnet or a superconducting main magnet 12 for generating a strong and in particular homogeneous main magnetic field 13 (static magnetic field B0 ). Furthermore, the magnetic resonance system 10 includes a patient receiving area 14 for receiving a patient. In the present exemplary embodiment, the patient receiving area 14 is formed cylindrically and is surrounded in the circumferential direction of the magnet unit 11 . In principle, however, different configurations of the patient receiving area 14 than the example described are also conceivable.

[0078] The patient can be positioned in the patient receiving area 14 by means of the patient support device 16 of the magnetic resonance...

Abstract

The invention relates to a local coil (26) comprising a flat support body (30), at least one ventilation opening (42), an antenna arrangement (34) for receiving radiofrequency signals in the frequency and power range of a magnetic resonance apparatus (10), the flat support body (30) being made of a reversibly deformable material and being adaptable to the physical shape of a patient (15). The invention also relates to a magnetic resonance system comprising a magnetic resonance device (10), a local coil (26) and an electrical connection line (27). The invention also relates to a method for producing a local coil (26) having at least one frame element (31), an intermediate space (38), at least one filling element (35) and a first housing (32) and a second housing (33). The invention also relates to a tool for use in a method of manufacturing the local coil (26).

Description

technical field [0001] The invention relates to a local coil comprising a flat carrier, at least one ventilation opening and an antenna arrangement for receiving radio frequency signals in the frequency and power range of a magnetic resonance system, wherein the flat carrier is reversibly deformable by means of Constructed of materials and matched to the patient's body shape. Furthermore, the invention relates to a magnetic resonance system comprising a magnetic resonance system, a local coil and electrical connecting lines, as well as a method and a tool for producing a local coil. Background technique [0002] A magnetic resonance tomograph is an imaging device which orients the nuclear spins of an examination object by means of a strong external magnetic field and excites them with an alternating magnetic field to precess around the orientation in order to image the examination object. The precession of the spins or the return from the excited state to a state with lower...
