Final answer:
The radiologic portion of the procedure is designated as 'radiological supervision and interpretation' when performed by two physicians, typically including a radiologist.
Step-by-step explanation:
When a procedure is performed by two physicians, the radiologic portion of the procedure is designated as radiological supervision and interpretation. This situation often arises in procedures where a radiologist, who specializes in interpreting medical images, works in conjunction with another physician who is performing a treatment or a diagnostic procedure. Radiography technicians, on the other hand, are skilled professionals who operate diagnostic imaging equipment, such as X-ray machines, computed tomography (CT) machines, and magnetic resonance imaging (MRI) scanners, to assist in the diagnosis and treatment of medical conditions.
