| 설명 | 인체의 장기나, 병적인 모양, 종양의 위치, 림프절의 비대 등에 대한 진단을 내리기 위해 시행하는 방사선학적인 검사방법이다. 현재 많이 쓰이고 있는 컴퓨터단층촬영술(CT: computerized tomography)과는 다른 방법으로 시행하며, 그 해상도가 컴퓨터단층촬영보다는 뛰어나 비록 고가이긴 하지만, 많이 쓰이고 있다. 또한 인체에 무해하고, 여러 가지 면에서 사람을 단층으로 분리시켜 볼 수 있는 등 장점이 많다. 단점은 심장박동기를 설치한 사람이나, 주위에 장을 띠는 물체를 몸에 지니고 있는 중환자 등에서는 이용할 수 없고, 복부장기에 대한 진단에는 컴퓨터단층촬영보다 불리한 것으로 되어 있으며, 무엇보다 설치비와 그 시술비가 비싸다는데 가장 큰 단점이 있다. |

| 설명 | 다른 말로 MRI=Magnetic Resonance Imaging 자기공명영상이라고도 한다. 인체의 장기나, 병적인 모양, 종양의 위치, 림프절의 비대 등에 대한 진단을 내리기 위해 시행하는 방사선학적인 검사방법이다. 현재 많이 쓰이고 있는 컴퓨터단층촬영(CT=computerized tomography)과는 다른 방법으로 시행하며, 그 해상도가 컴퓨터단층촬영보다는 뛰어나 비록 고가이긴 하지만, 많이 쓰이고 있다. 또한 인체에 무해하고, 여러 가지 면(plane)에서 사람을 단층시켜 볼 수 있다. 단점은 심장박동기를 설치한 사람이나, 주위에 자장을 띠는 물체를 몸에 지니고 있는 중환자 등에서는 이용할 수 없고, 복부장기에 대한 진단에는 컴퓨터단층촬영보다 떨어지는 것으로 되어 있다. |

| toroidal magnetic cusps | A hybrid confinement scheme operating at high beta. A region of closed toroidal magnetic flux with high-beta plasma is separated by a narrow sheath from the surrounding field, which contains externally produced poloidal components arranged in a toroidal line-cusp configuration. Plasma migrating to the outer sheath is temporarily mirror-confined before being removed in a divertor system. (09 Oct 1997) |

| advanced toroidal facility | <physics> A large stellarator device developed at Oak Ridge National Lab (ORNL), but now retired. Acronym: ATF (09 Oct 1997) |
|---|---|
| toroidal | <radiobiology> In the shape of a torus, or doughnut. Or: Coordinate indicating which part of the torus a particle is in. (Azimuthal coordinate, toroidal angle, etc.) Or: General term referring to toruses as opposed to other geometries. (for example, tokamaks and stellarators are examples of toroidal devices.) (09 Oct 1997) |
| toroidal beta | <radiobiology> Plasma beta using the toroidal magnetic field, i.e. Plasma pressure divided by toroidal field pressure. See: beta. (09 Oct 1997) |
| toroidal current | <radiobiology> Current flowing in the toroidal direction (the long way) around a torus. (As distinct from poloidal currents flowing through the centre of the torus and around to the outside, the short way.) (09 Oct 1997) |
| toroidal divertor | <radiobiology> Divertor created by extracting toroidal field field lines at some point, forming an external loop outside the torus. Has the disadvantages that it breaks the axial symmetry of the torus, which converts a relatively simple, mostly 2-dimensional geometry to a comples 3-dimensional geometry. For an illustration refer to page 135 of Gross (reference 4). (09 Oct 1997) |
| toroidal field coils | <radiobiology> Coils in a toroidal system, typically wound around the torus in a solenoid-like arrangement, used to generate the toroidal magnetic field. Each turn completely surrounds the plasma. (09 Oct 1997) |
| toroidal flux | <radiobiology> Magnetic field flux in the toroidal direction. See: magnetic fields. (09 Oct 1997) |
| magnetic | 1. A magnet. "As the magnetic hardest iron draws." (Milton) 2. Any metal, as iron, nickel, cobalt, etc, which may receive, by any means, the properties of the loadstone, and which then, when suspended, fixes itself in the direction of a magnetic meridian. Source: Websters Dictionary (01 Mar 1998) |
| magnetic attraction | The force that draws iron or steel toward a magnet. (05 Mar 2000) |
| magnetic axis | <physics> This typically refers to the location of the innermost flux surface in a toroidal device, the one which encloses no volume and has therefore degenerated from a flux surface into a single field line. Roughly, the circle through the middle of the dough of the donut. Additionally, in systems with magnetic islands (see entry below), each island has a local magnetic axis, distinct from the overall magnetic axis of the torus. (09 Oct 1997) |
| magnetic confinement | <physics> Use of magnetic fields to confine a plasma. (Confinement involves restricting the volume of the plasma and/or restricting particle or energy transport from the centre of the plasma to the edge.) (09 Oct 1997) |
| magnetic confinement fusion | <physics> Method of fusion which uses magnetic fields / magnetic bottles to confine a hot plasma until fusion occurs. (09 Oct 1997) |
| magnetic field | The sphere of influence of a magnet. (05 Mar 2000) |
| magnetic field gradient | In magnetic resonance imaging, a magnetic field that varies with location, superimposed on the uniform field of the magnet, to alter the resonant frequency of nuclei and allow recovery of their spatial position. Synonym: field gradient. (05 Mar 2000) |
| magnetic implant | A tissue-tolerated, magnetised metal placed within the bone to aid in denture retention; a similar magnet is placed in the overlying denture to complete the field. (05 Mar 2000) |
