Abstract

Seven Figures.  —In the INSTRUMENTATION article, "Isometric, Three-Dimensional Viewing of Ultrasonograms," published in the December Archives (93:1362-1365, 1975), the legends for the seven illustrations were in error.The legend for Fig 1 should have read "Fig 1.—Schematic B-scan illustrating isometric tilting. Top, Schematic drawing of four simulated echoes as seen on B-scan, in which two-dimensional position is optimally seen, but echo amplitude is not apparent. Center, Display `tilted' in isometric view so that amplitude as well as relative position is seen. Bottom, Display `tilted' 180° from top view, giving optimal appreciation of relative amplitude but degrading position information."The incorrect designation (in italics) and the correct legend for the other six illustrations follow:

Fig 2, A: Fig 2.  —Conventional sector B-scan of eye with vitreous hemorrhage and retinal detachment, shown devoid of gray scale. Scan is horizontal plane of eye with cornea to left and optic nerve to right.
