auditory field the space or range within which stimuli will be perceived as sound.
disturbed energy field a nursing diagnosis defined as a disruption of the flow of energy surrounding a person's being that results in disharmony of the body, mind, and/or spirit.
energy field the flow of energy surrounding a person.
extended field in radiation therapy, such as for malignant lymphoma, an area of irradiation beyond the involved field. See also under irradiation.
high-power field the area of a slide visible under the high magnification system of a microscope.
individuation field a region in which an organizer influences adjacent tissue to become a part of a total embryo.
inverted Y field in radiation therapy, such as for malignant lymphoma, a circumscribed area of irradiation below the diaphragm, covering the spleen, extending down the midline, and branching inferiorly to form tails across the inguinal areas.
involved field in radiation therapy, such as for malignant lymphoma, the irradiated area when irradiation has been limited to sites of detectable macroscopic disease. See also under irradiation.
low-power field the area of a slide visible under the low magnification system of a microscope.
magnetic field that portion of space about a magnet in which its action is perceptible.
mantle field in radiation therapy, such as for malignant lymphoma, a circumscribed area of irradiation around the shoulders and chest, including the neck, clavicular regions, axillae, and mediastinum. See also under irradiation.
morphogenetic field an embryonic region out of which definite structures normally develop.
operating field (operative field) an isolated area where surgery is performed; it must be kept sterile by aseptic techniques (see surgical asepsis). Called also surgical field.
sterile field an operative field that is properly sterile according to surgical asepsis. It includes having all furniture and equipment covered with sterile drapes and all personnel being properly attired.
surgical field operative field.
visual field (F) (vf) the area within which stimuli will produce the sensation of sight with the eye in a straight-ahead position.

the sphere of influence of a magnet.

magnetic field

Etymology: Gk, magnesia, lodestone; AS, feld
the region around any magnet in which its effects can be detected.

magnetic field

An MRI term for the magnetic lines of force (flux) which extend from a north polarity and enter a south polarity of a magnet to form a closed loop around the outside of a magnetic material.

Magnetic field

The three-dimensional area surrounding a magnet, in which its force is active. During MRI, the patient's body is permeated by the force field of a superconducting magnet.

magnetic field (MF),

n the lines of force that surround a moving charged particle or a magnet.
