| 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. |

| integrated neutron flux | <radiobiology> Sum (integral) of the neutron flux (neutrons per unit time per unit area, see flux) over all time, total number of neutrons which passed through a unit area. Important figure-of-merit in testing effects of neutron radiation on materials, and in assessing how long such materials can survive exposure to neutron sources (such as fission reactor cores and D-T fusion plasmas).

| unidirectional flux | The flux of a substance from one surface of a boundary layer or membrane to the other, disregarding any counterbalancing flux in the other direction, as measured by tracer technique. (05 Mar 2000) |
| flux | <radiobiology> The total amount of a quantity passing through a given surface per unit time. Typical quantities include (magnetic) field lines, particles, heat, energy, mass of fluid, etc. Common usage in plasma physics is for flux by itself to mean magnetic field flux, unless specified otherwise.

| flux, light | <microscopy> Sometimes called luminous flux, the visible portion of the radiant energy emitted by a light source. It is measured in lumens per solid angle. In electrical engineering, it is analogous to the lines of force in a magnetic field, spoken of as magnetic flux. (05 Aug 1998) |

| 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 flux |
Magnetic flux, is a measure of quantity of magnetism, taking account of the strength and the extent of a magnetic field. The flux through an element of area perpendicular to the direction of magnetic field is given by the product of the magnetic field density and the area element. More generally, magnetic flux is defined by a scalar product of the magnetic field density and the area element vector. ...
