The correct term to describe c-arm imaging tables is radiolucent. This means that x-rays can pass through the table, allowing the patient to be imaged without obstruction. On the other hand, radiopaque means that x-rays cannot pass through the object, making it visible on an x-ray image. This area on the c-arm table is described as the imaging area. You will typically want as large an imaging area as possible. Pain management tables, Vascular imaging tables, Urology tables, and some surgical tables have large radiolucent imaging areas. These c-arm compatible imaging table tops are normally metal-free and made out of carbon fiber or some other composite material.
