What is regarded as the depth of peak dose (D-Max) for clinical electron beams?

The depth of peak dose (D-Max) for clinical electron beams is typically around 1.0 cm. This point represents the depth at which the deposited dose of radiation is highest when using electron therapy, making it crucial for clinicians aiming to maximize treatment effectiveness while minimizing exposure to surrounding healthy tissues.

In clinical practice, the D-Max is significant because it helps determine the optimal placement of the treatment beam relative to the tumor. With electron beams, the dose distribution is primarily superficial, which is advantageous for treating skin lesions or tumors located just beneath the surface of the skin. Knowing that the peak dose occurs at approximately 1.0 cm allows medical dosimetrists and radiation oncologists to plan treatments accurately and ensure that the prescribed dose is delivered at the intended location effectively.

The depth of D-Max can vary slightly based on factors such as the energy of the electron beam and the specific treatment technique being used. However, 1.0 cm serves as a standard reference point for many clinical applications involving electron therapy.
