Whole-body coil arrangement for an open magnetic resonance scanner for use with a second diagnostic and/or therapeutic modality
A whole-body coil arrangement for an open magnetic resonance scanner for use with a second diagnostic and/or therapeutic modality is proposed. The whole-body coil arrangement includes at least one coil conductor and a radio-frequency shield. The whole-body coil arrangement is embodied at least in part as essentially transparent to the second modality.
1. A whole-body coil arrangement for an open magnetic resonance scanner for use with a second diagnostic and/or therapeutic modality, comprising:
a coil conductor;
spaced-apart magnet sections;
a radio-frequency shield extending through bores of the spaced apart magnet sections that covers an open area between the spaced apart magnet sections; and
a plastic cylindrical carrier element;
wherein the coil conductor is constructed from a metal layer applied to an inside surface of the carrier element, wherein a thickness of the metal layer is chosen according to a penetration depth of the second diagnostic and/or therapeutic modality;
wherein the radio-frequency shield is at least partially a fine-meshed grid and is applied to a surface of the carrier element opposite the inside surface;
wherein the coil conductor and/or the radio frequency shield consists of aluminum;
wherein the second diagnostic and/or therapeutic modality comprises an emitter for generating radiations, and
wherein the whole-body coil arrangement is configured to be at least partially transparent in the open area such that the whole-body coil arrangement is penetrable by the radiations generated by the second diagnostic and/or therapeutic modality.
2. The whole-body coil arrangement as claimed in claim 1 , wherein the whole-body coil arrangement is configured to be transparent in the open area of the open magnetic resonance scanner.
3. The whole-body coil arrangement as claimed in claim 1 , wherein the whole-body coil arrangement is configured to be essentially transparent.
4. The whole-body coil arrangement as claimed in claim 1 , wherein an attenuation property of the whole-body coil arrangement is homogenous in the transparent area.
5. The whole-body coil arrangement as claimed in claim 1 , wherein the whole-body coil arrangement is a cylinder comprising two cylindrical and/or rectangular coaxial magnet sections.
6. The whole-body coil arrangement as claimed in claim 1 , further comprising a rotator for rotating the whole-body coil arrangement so that the coil conductor is rotated out of influence of the second diagnostic and/or therapeutic modality.
7. An open magnetic resonance scanner, comprising:
spaced apart magnet sections; and
a whole-body coil arrangement for use with a second diagnostic and/or therapeutic modality comprising an emitter for generating radiations, the whole-body coil arrangement comprising:
a coil conductor;
a radio-frequency shield extending through bores of the spaced apart magnet sections of the open magnetic resonance scanner that covers an open area between the spaced apart sections; and
a plastic cylindrical carrier element;
wherein the coil conductor is constructed from a metal layer applied to an inside surface of the carrier element, wherein a thickness of the metal layer is chosen according to a penetration depth of the second diagnostic and/or therapeutic modality;
wherein the radio-frequency shield is at least partially a fine-meshed grid and is applied to a surface of the carrier element opposite the inside surface;
wherein the coil conductor and/or the radio frequency shield consists of aluminum;
wherein the whole-body coil arrangement is configured to be at least partially transparent in the open area such that the whole-body coil arrangement is penetrable by the radiations generated by the second diagnostic and/or therapeutic modality.
8. The open magnetic resonance scanner as claimed in claim 7 , wherein the whole-body coil arrangement is mounted to be rotatable.
9. The open magnetic resonance scanner as claimed in claim 7 , wherein the whole-body coil arrangement is a cylinder.
10. A medical device, comprising:
an open magnetic resonance scanner comprising a whole-body coil arrangement and spaced apart magnet sections, the whole-body coil arrangement comprising:
a coil conductor,
a radio-frequency shield extending through bores of the spaced apart magnet sections of the open magnetic resonance scanner that covers an open area between the spaced apart magnet sections; and
a plastic cylindrical carrier element;
wherein the coil conductor is constructed from a metal layer applied to an inside surface of the carrier element;
wherein the radio-frequency shield is at least partially a fine-meshed grid and is applied to a surface of the carrier element opposite the inside surface;
wherein the coil conductor and/or the radio frequency shield consists of aluminum; and
a second diagnostic and/or therapeutic modality comprising an emitter for generating radiations, wherein a thickness of the metal layer is chosen according to a penetration depth of the second diagnostic and/or therapeutic modality,
wherein the whole-body coil arrangement is configured to be at least partially transparent in the open area such that the whole-body coil arrangement is penetrable by the radiations generated by the second diagnostic and/or therapeutic modality.
11. The medical device as claimed in claim 10 , wherein the second modality is a beta radiation modality and/or an X-ray radiation modality.
