(15) To establish the extent to which a parallax-effect of differing angles of X-ray beam relative to the patient can influence the radiologic assessment of carinal level, we measured the tracheal-vertebral distance at the carina in 29 lateral radiographs of neonates, infants and children, prepared diagrams of the loci of carinal beam intercept of the vertebral column for different angles of beam to body, from tracings of lateral radiographs of two 2-week-old infants, one with trachea of normal length and one with short trachea; of a nine-year-old child with short trachea, and of a ten-year-old with normal trachea, and made radiographs of a postmortem tracheobronchogram of a two-day-old infant at different beam angles.
(16) This prediction was confirmed by the experimental determination of chromatic parallax for two commercially available achromatizing lenses.
(17) The hypothesis was tested that the coupling of parallax shifts between objects depicted on a monitor screen around a fixation point with the head movements of an observer viewing this screen monocularly around a point coinciding with the fixation point is sufficient to create a convincing depth impression and to enable the observer to make reliable estimations of depth.
(18) Traditionally, parallax disparities refer to points that are well defined within the objects, such as edges or boundaries.
(19) Additional experiments indicated that the deficit in performance by MS cats was not reduced either by the administration of amphetamine or by increases in cues for motion parallax.
(20) The next step was to demonstrate that parallax is also significant as a way of segmenting the visual scene into separate objects.
Triangulation
Definition:
(n.) The series or network of triangles into which the face of a country, or any portion of it, is divided in a trigonometrical survey; the operation of measuring the elements necessary to determine the triangles into which the country to be surveyed is supposed to be divided, and thus to fix the positions and distances of the several points connected by them.
Example Sentences:
(1) Diagnostic pitfalls can generally be avoided by insisting on the opportunity for clinical-radiologic-pathologic correlation ("triangulation") before a final diagnosis is made.
(2) The psychological-interpersonal movement into triangulated oedipal object relations is mediated by the elaboration of mature forms of primal scene fantasies in conjunction with the development of a "transitional oedipal relationship" to the mother.
(3) The ultimate triangulation is that the Tories will represent the interests of both the bosses and the workers.
(4) Two horses with osteochondrosis lesions of the shoulder were examined arthroscopically and debrided with instrument triangulation.
(5) Improved treatment of spinal deformities in the elderly and osteoporotic population is dependent on improving the fixation at the metal-bone interface of spinal implants Particularly in osteoporotic vertebrae, the strength of fixation of two triangulated pedicle screws is better than either laminar hooks or single pedicle screws.
(6) The acceptance of the ambivalence and triangulation have the effect that the creative aspects in the later wish for a child are more powerful than the narcissistic or depressive parts.
(7) The cytotoxicities of the modified alkaloids in the in vitro P-388 system were not significantly increased over the unmodified alkaloids, suggesting that the triangulation hypothesis does not apply in this series at least.
(8) Trimming, triangulating, sneaking small policy advantages and wallowing in the narcissism of small differences, the parties seemed locked in a distant and disreputable Westminster charade.
(9) The evaluation phase incorporated the multi-method approach of triangulation to gather data during the implementation phase of the mentored placement.
(10) We developed some instruments to resolve these problems; i.e., scopes with a large diameter for high resolution, a triangulation instrument for multiple cannulations, a needle set-up jig for disk traction suture, a step cannulation system and a two-channel cannula for operating in the narrow lower joint space and a fixing jig for cannulas in the upper and lower joint space to observe the same portion of the discal tissue from both joint space during disk suturing.
(11) Foreign bodies near the posterior ocular wall were optimally evaluated by both radiographic and ultrasonic localization methods to avoid the inherent error of the x-ray triangulation system.
