ABSTRACT:
A B-scan ultrasonoscope which can be used for scanning tissue, for example the human eye, and displays the shape and character of the tissue. The echo pulses received are converted into digital signals whose amplitudes represent the reflectivity of the tissue. The digital signals are then displayed on a color display in accordance with a desired color scale, with individual digital increments respectively representing preselected colors. Alternate increments are maintained as black, whereby the active colors are interleaved with bands of black. In this manner, tissue interfaces are more easily seen and visual acuity is improved.
