A one piece plastic drain pan (24) is mounted to an examination end (14) of a urology table (10). The pan includes an integrally constructed vertical inner end wall (28), a sloping outer end wall (34), a pair or opposite side walls (30), (32), and a bottom wall (36) through which a drain port (38) is defined. The plastic material, particularly in the side walls has sufficient plastic memory that as a physician leans against the outer end wall (34), the side walls bow outward compressing the end walls toward each other. When the pressing force is removed, the end walls return themselves to the non-flexed position and the end walls move apart. Plates (50, 52) clamp the inner end wall (28) of the plastic drain pan securely therebetween. The plates have flanges (54) which are received in mating slots (56) in the examination end (14) of the urology table. A folding screen arrangement (60) provides a convenient storage surface for examination tools and separates stones, tissue, and the like from drained fluids. The drain pan has integrally connected horizontal flanges (42, 44) adjacent the side walls and a rolled flange along the outer end wall.

An x-ray imaging system incorporating a television imaging chain is disclosed. The system includes automatic gain control circuitry, operable upon the video signal produced by the camera of the television imaging chain. The gain control circuitry affords automatic gain control capability for increasing the video gain in response to an undesired decrease in video output signal level. The gain control circuitry, however, is constrained in that it includes circuitry for establishing a minimum video gain which is always maintained during a study, irrespective of increases in brightness of an overall sample window area of the image, which could otherwise cause undesirable darkening of areas of interest in the image when the sample window also includes uninteresting structure which happens to exhibit a bright field.
