A characteristic of a pixel or voxel that is square or cubic respectively Compare to non-isotropic See the Caret (for Pfile/Functional files) and Surefit (for 2D and 3D anatomical files) pages for instructions on converting non-isotropic voxels to isotropic voxels
Same in all directions; the isotropicity of space means that the outcome of an experiment performed on a closed system does not depend on the orientation of the closed system
Having properties that are the same regardless of the direction of measurement In the isotropic state, all directions are indistinguishable from each other See also anisotropic
In wireless, a theoretical "unity" (0 dB) gain antenna used as a measurement reference Has the assumed characteristic of receiving or transmitting equally well in all directions A dipole antenna roughly approximates an isotropic antenna Back to top kHz Kilohertz, 1,000 Hertz, or one thousand cycles per second Back to top Lavalier Microphone A type of miniature microphone that is usually worn fastened to clothing somewhere near the user's mouth Also referred to as a clip-on or lapel microphone
Equal in all directions Isotropic scattering occurs when light is scattered equally over 4pi steradians Isotropic reflection, in contrast, usually refers to a surface that may have a directional preference, but one that does not depend on the azimuth of the incident vector
