Which element relates to electrode placement in a dosimetric plan?

• A. Electrode placement
• B. Expected outcomes
• C. Safety checks
• D. Modality choice

Answer: (A)

Where the electrodes are placed determines the path of the current and the tissue that receives the dose. In a dosimetric plan, specifying electrode placement directly sets where contact occurs, the size and orientation of the electrodes, and how the current distributes across the treatment area. This controls current density, coverage, and penetration, which in turn drives the therapeutic effect and safety. If placement is off, the target tissue may not receive adequate stimulation or heating, and nearby structures could be affected.

Other elements like what outcomes you expect, safety checks, or the overall modality describe goals, safety procedures, or type of therapy, but they do not define where the electrodes actually go.
