What key factor does quality control ensure regarding patient doses?

Quality control in medical imaging and radiation therapy is essential to ensure that patient doses are delivered at optimal levels for both safety and efficacy. This involves implementing procedures and standards to monitor and assess equipment performance, so that the delivered doses are accurate and within clinically acceptable ranges.

By adhering to quality control protocols, healthcare providers can confirm that the amounts of radiation or medication administered to patients are neither too high (which could lead to harmful side effects) nor too low (which might compromise the effectiveness of the treatment). This balancing act seeks to achieve the best possible clinical outcomes while minimizing risk to the patient.

Maintaining optimal dose levels is crucial to ensuring patient safety and the therapeutic effectiveness of treatments in various medical contexts, making this the correct choice.
