| working through | In psychoanalysis, the process of obtaining additional insight and personality changes in a patient through repeated and varied examination of a conflict or problem; the interactions between free association, resistance, interpretation, and working out constitute the fundamental facets of this process.

| through | 1. From end to end of, or from side to side of; from one surface or limit of, to the opposite; into and out of at the opposite, or at another, point; as, to bore through a piece of timber, or through a board; a ball passes through the side of a ship. 2. Between the sides or walls of; within; as, to pass through a door; to go through an avenue. "Through the gate of ivory he dismissed His valiant offspring." (Dryden) 3. By means of; by the agency of. "Through these hands this science has passed with great applause." (Sir W. Temple) "Material things are presented only through their senses." (Cheyne) 4. Over the whole surface or extent of; as, to ride through the country; to look through an account. 5. Among or in the midst of; used to denote passage; as, a fish swims through the water; the light glimmers through a thicket. 6. From the beginning to the end of; to the end or conclusion of; as, through life; through the year. Origin: OE. Thurgh, urh, uruh, oruh, AS. Urh; akin to OS. Thurh, thuru, OFries. Thruch, D.

| through drainage | Drainage obtained by the passage of a perforated tube, open at both extremities, through a cavity; in addition, the cavity can be washed out by a solution passed through the tube. (05 Mar 2000) |
| through transfer imaging | The production of an ultrasound image by detection and analysis of sound on the opposite side of the body from the emitting transducer. Synonym: through transfer imaging. (05 Mar 2000) |
| endorectal pull-through procedure | Removal of diseased rectal mucosa along with resection of the lower bowel, followed by anastomosis of the proximal stump to the anus, in order to spare rectal muscle function. (05 Mar 2000) |
| annular illumination | <microscopy> The result of placing a stop in the first focal plane of the condenser to produce an illuminating cone of light with all the light flux near the surface of the cone. The central part of the cone will be dark. This arrangement is often used for a darkfield effect in low-power work by transmitted light. The condenser must be correctly focused and centreed. By reflected light, darkfield illumination is attained with an annular con-denser fitted around the objective for opaque objects. Annular illumination implies that the object is lighted from all sides. (05 Aug 1998) |
| bright field illumination | <microscopy> The method of lighting the specimen with a solid cone of rays. Transmitted bright field illumination is performed by a substage condenser. Reflected bright field illumination is performed by a vertical illuminator. Compare: dark field illumination (05 Aug 1998) |
| vertical illumination | <microscopy> Bright field illumination by light from the objective which is reflected or scattered from the (usually opaque) object. Illumination is by means of a vertical illuminator placed above the objective. Light is brought into a side tube and directed toward the back aperture of the objective by a tiny mirror or prism, or else by a full-aperture transparent-reflector (thin glass plate) 45[macron] to the axis of the bodytube. (05 Aug 1998) |
| central illumination | axial illumination |
| contact illumination | Illumination of the eye by means of an instrument in contact with the cornea or bulbar conjunctiva. Critical illumination, the precise focusing of the light source directly upon the object being examined. Dark-field illumination, a procedure in which a black circular shield is used to block the majority of the vertically directed rays of light (e.g., the field is dark), and a circumferential, suitably angled, mirrored surface is used to direct the peripheral rays horizontally against the object, thereby reflecting the light vertically through the objective lens and along the optical axis; thus, the object is well illuminated in a contrasting dark background. Synonym: dark-ground illumination. (05 Mar 2000) |
| dark field illumination | <microscopy> Any method of illumination which illuminates the specimen but does not admit light directly to the objective. It may be by substage (dark field) condensers, by stagespot lighting, by special condensers fitted around special objectives for reflected illumination or by the slit ultramicroscope. (05 Aug 1998) |
| through illumination |
Passage of light through the walls of an organ or cavity for medical examination. SEE: transillumination.
