individuation field

field (fēld)

1. an area or open space, as an operative field or visual field.

2. a range of specialization in knowledge, study, or occupation.

3. in embryology, the developing region within a range of modifying factors.

auditory field  the space or range within which stimuli may be perceived as sound.

individuation field  a region in which an organizer influences adjacent tissue to become a part of a total embryo.

morphogenetic field  an embryonic region out of which definite structures normally develop.

visual field  (F) (vf) the area within which stimuli will produce the sensation of sight with the eye in a straight-ahead position.

individuation field

n.

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.
