| transverse carpal ligament | <anatomy> A strong fibrous band crossing the front of the carpus and binding down the flexor tendons of the digits and the flexor carpi radialis tendon and the median nerve; in so doing it creates the carpal tunnel. Synonym: retinaculum flexorum, deep part of flexor retinaculum, flexor retinaculum, ligamentum carpi transversum, ligamentum carpi volare, volar carpal ligament. (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) |
| PA projection | The standard frontal chest film projection; radiographic skull projection with the petrous ridge superimposed on the orbits. Synonym: posteroanterior projection. (05 Mar 2000) |
| visual projection | A perceptual synthesis involving visual mechanisms. (05 Mar 2000) |
| Rhese projection | Oblique radiographic view of the skull to show the optic foramen. (05 Mar 2000) |
| Granger projection | G. View, reversed half-axial view; uncommonly used PA view of the skull. (05 Mar 2000) |
| Waters' projection | A PA radiographic view of the skull made with the orbitomeatal line at an angle of 37 |
| point projection | <microscopy> A method of producing enlarged images by means of X rays. The specimen is placed close to a point source of X rays and the magnification achieved is the ratio of source-image to source-object distance. Resolution depends primarily on the diameter of the source. (05 Aug 1998) |
| cross-table lateral projection | <radiology> Lateral projection radiography of a supine subject using a horizontal X-ray beam. (05 Mar 2000) |
