Potter Bucky Diaphragm Victor Model THE degree of high quality radiographs with the Potter-Bucky Diaphragm isdependent entirely on the success of the manufacturer in the application ofthe principles involved. The Victor Model of the Potter-Bucky Diaphragm is the result of intensiveexperimental work on the part of Victor Engineers in collaboration with Dr.Potter, and was not announced until it proved itself to have reached a muchhigher degree of perfection than ever before attained. The design of the grid in the Victor Model differs from that of any other con-struction, and due largely to this the following points of superiority are realized : 1.
