Authorization is indeed necessary for performing an ultrasound on a regal patient. This is primarily due to the protocols that govern healthcare practices, which mandate that any medical procedure, including imaging studies like ultrasounds, must be authorized to ensure that it is clinically justified and appropriate for the patient. Authorization helps to protect the patient's rights and ensures that they are fully aware of the procedure being performed on them.

Additionally, the authorization process typically involves obtaining a signed consent from the patient or their legal representative. This consent confirms that the patient understands the nature of the ultrasound, its purpose, the potential risks, and any alternatives available. Without proper authorization, there could be legal and ethical implications for the healthcare provider, as well as concerns regarding patient safety and informed consent.

The other options suggest scenarios where authorization may not be necessary, but these do not align with standard medical practice, which prioritizes patient ownership of their healthcare decisions.
