| aberration, spherical | <optics> A lens defect whereby image forming rays of one colour, passing through the outer zones of a lens come to focus at a different distance from the lens than do those of more central rays. With a simple spherical (or plano-spherical) lens the outer rays always meet the axis closer to the lens than do more central rays and the lens is uncorrected or undercorrected. When the reverse is true the lens has been overcorrected. (05 Aug 1998) |

| spherical | Pertaining to, or shaped like, a sphere. (05 Mar 2000) |
| spherical aberration | <microscopy> A lens defect in which image forming rays passing through the outer zones of the lens focus at a distance from the principal plane, different from that of the rays passing through the centre of the lens. The aberration caused by (near-paraxial) monochromatic light rays or electron beams passing through different radii of a lens not coming to the same focus. (05 Aug 1998) |
| spherical amalgam | An alloy for dental amalgam composed of spherical particles instead of filings. (05 Mar 2000) |
| spherical form of occlusion | An arrangement of teeth which places their occlusal surfaces on the surface of an imaginary sphere (usually 8 inches in diameter) with its centre above the level of the teeth. See: Monson curve. (05 Mar 2000) |
| spherical lens | A lens in which all refracting surfaces are spherical. (05 Mar 2000) |
| spherical nucleus | Spinal nucleus of accessory nerve, a slender column of motor neurons extending longitudinally through the central part of the ventral horn of the upper five segments of the spinal cord, giving origin to the spinal part of the accessory nerve. Synonym: nucleus spinalis nervi accessorii, globosus nucleus. (05 Mar 2000) |
| spherical recess | A rounded depression on the inner wall of the vestibule of the labyrinth, lodging the sacculus. Synonym: recessus sphericus, fovea hemispherica, fovea spherica. (05 Mar 2000) |
| anteroposterior projection | The alternative frontal radiographic projection, used mainly in bedside or portable radiography. Synonym: anteroposterior projection. (05 Mar 2000) |
| apical lordotic projection | In computed tomography or other imaging techniques requiring reconstruction from multiple projections, an algorithm for calculating the contribution of each voxel of the structure to the measured ray data, in order to generate an image; the oldest and simplest method of image reconstruction. Synonym: apical lordotic projection. (05 Mar 2000) |
| AP projection | The alternative frontal radiographic projection, used mainly in bedside or portable radiography. Synonym: anteroposterior projection. (05 Mar 2000) |
| axial projection | Radiographic projection devised to obtain direct visualization of the base of the skull. Synonym: axial view, base projection, submental vertex projection, submentovertical projection, verticosubmental view. (05 Mar 2000) |
| base projection | Radiographic projection devised to obtain direct visualization of the base of the skull. Synonym: axial view, base projection, submental vertex projection, submentovertical projection, verticosubmental view. (05 Mar 2000) |
| Caldwell projection | Inclined PA radiographic projection devised to permit visualization of orbital structures unobstructed by the petrous ridges. Synonym: Caldwell view. (05 Mar 2000) |
| radiography, dual-energy scanned projection | A method of producing a high-quality scan by digitizing and subtracting the images produced by high- and low-energy X-rays. (12 Dec 1998) |
