Computed tomography

- Same as computerised axial tomography. abbr ct
- A technique that produces a computer-processed x-ray image of a cross section of an internal organ or tissue.
- Technique by which radiation passing through an object is displayed as one slice or layer of that object at a time. image data are processed in three dimensions. conductance (g): transmission of electric current through a material. measured in siemens (s). inversely related to resistance r (ohms). conduction, thermal: heat transfer occurring when more energetic particles collide with — and thus impart some of their heat energy to — adjacent less energetic (slower moving) particles. this action is passed on from one atom (or free electron) to the next in the direction of cooler regions. thus, heat always flows from a warmer to a cooler region. compare conductivity, thermal; thermal diffusion. conductivity, electrical (s): ability of material to transmit electric current. measured in siemens per meter. inversely related to resistivity r. conductivity, thermal (k): material property defining the relative capability to carry heat by conduction in a static temperature gradient. conductivity varies slightly with temperature in solids and liquids and with temperature and pressure in gases. it is high for metals (copper has a k of 380 w·m–1·k–1) and low for gases and porous materials (concrete has a k of 1.0 w·m–1·k–1). compare conduction, thermal.
- Метод, с помощью которого излучение, проходящее через объект, отображается как один фрагмент или слой этого объекта за раз. данные изображения обрабатываются в трех измерениях. проводимость (g): передача электрического тока через материал. измеряется в сименсах (с). обратно пропорционально сопротивлению r (ом). проводимость, тепловая: передача тепла происходит, когда более энергичные частицы сталкиваются и, таким образом, передают часть своей тепловой энергии соседним менее энергичным (более медленным) частицам. это действие передается от одного атома (или свободного электрона) к следующему в направлении более холодных областей. таким образом, тепло всегда перетекает из более теплой области в более холодную. сравните проводимость, теплопроводность; термодиффузия. электропроводность (электрическая): способность материала передавать электрический ток. измеряется в сименсах на метр. обратно пропорционально удельному сопротивлению r. теплопроводность (k): свойство материала, определяющее относительную способность переносить тепло за счет проводимости в статическом температурном градиенте. проводимость незначительно меняется в зависимости от температуры в твердых телах и жидкостях, а также от температуры и давления в газах. он высок для металлов (медь имеет k 380 вт·м–1·к–1) и низок для газов и пористых материалов (бетон имеет k 1,0 вт·м–1·к–1). сравните проводимость, теплопроводность.
