Answer #1

Image acquisition depends on the activity administered. Administered activity is characterized by the plot of NEC or noise equivalent counts. When the activity is increased up to the peak, the dose of radiation to the patient is increased and time for image acquisition is decreased.

Increasing the activity also increases radiation dose even to the staff who is involved in administering activity. Increasing administered activity has no such effectiveness in improving image quality. These are the drawbacks.
