✦ Synopsis

We introduce a simple ray tracing method for measuring the vertex radius of curvature in situ, based on projecting spot array rays onto the surface of an aspheric mirror, and receiving the incident and the reflected rays. The method was used to measure the vertex radiuses of curvature of a spherical mirror and a paraboloidal mirror, the relative accuracy of better than 0.5% has been obtained.

A method is described in which the volumes of intracerebral haematomas were measured by a method of best-fitting circles, in 23 consecutive patients. The results were compared with computer measurements of the haematoma volumes. The two measures corresponded well: mean difference 0.14 cc (-0.5%), ra
