Abstract

Apparatus and methods for determining cradle support elevation in an imaging system are described. In one form, the apparatus includes a support rail secured to and between table support legs of a table arrangement. The support rail is maintained substantially parallel with the cradle support. An encoder, coupled to the support rail, generates signals indicative of the cradle support elevation. The encoder signals can be used to determine, using a linear function, cradle support elevation. More specifically, although the cradle support movements are non-linear, the cradle support elevation apparatus provide linear feedback which may be used to determine cradle support elevation.
