Abstract

A conveyor (12) moves a workpiece (WP) past an x-ray source (14) to detect existence and location of any undesirable material included in the workpiece, such as bones, fat, metal, etc. Thereafter, the conveyor carries the workpiece further, wherein a cutter (22) segments the detected undesirable material from the workpiece into a segmented portion (SP) having a visually distinguishable shape, such as square, round, triangular, etc. A worker stationed downstream of the cutter along the conveyor may then easily spot the segmented portion (SP) in a distinguishable shape and offload the segmented portion from the conveyor, while leaving the rest of the workpiece (WP) on the conveyor for further processing. Alternatively, a pickup device (24) may be used to automatically offload the segmented portion from the conveyor. A computer (18) keeps track of the locations of the workpiece and the segmented portion at all times.
