PRODUCT FEATURES: Customized for use with complementary RaySafe Pro-Stand and Pro-Slit Camera X-ray Pinhole Assemblies One of the specifications and chief features of an X-ray tube is its focal spot size, a very important factor in the resolution to be achieved during a radiologic examination. A small focal spot size will provide the maximum resolution. However, there are other factors in the construction of an X-ray tube, such as the heat dissipation within the target, which limits the minimum size of the target. In order to determine the focal spot size of an X-ray tube, a small and precise pinhole is often used. Its size must be very small compared to the focal spot to be measured. TECHNICAL DATA
