Lateral scattering of electrons in bone can significantly impact treatment planning by causing the development of a high dose region in the patient. When electrons are directed toward a treatment area, their interaction with denser tissues, such as bone, leads to scattering. This scattering effect can result in electrons being redirected laterally, which may create areas of increased dose deposition adjacent to the target volume.

In the context of treatment planning, this phenomenon is crucial because it can alter the expected dose distribution, particularly near the interface between soft tissue and bone. This means that while the primary beam is directed towards the tumor, the scattering can inadvertently increase the dose in surrounding normal tissues or even lead to hotspots where the dose is higher than intended. Thus, understanding how electron lateral scattering affects dosimetry is essential for achieving accurate and effective treatment outcomes while minimizing damage to healthy tissues.

The other options do not accurately reflect the consequences of lateral scattering in this context. For example, while decreased dose accuracy and uneven dose distribution might be concerns in broader contexts, the primary and most significant consequence of lateral scattering specifically relates to the creation of high dose regions. Overall, acknowledging this scattering effect is critical for effective treatment planning and ensuring patient safety.
