Imaging instruments have the _____ output intensity.

Imaging instruments have the _____ output intensity.

• A. Lowest
• B. Highest
• C. Moderate
• D. Variable

Answer: (A)

In diagnostic ultrasound, safety drives the design and use of the equipment. The beam is produced at the lowest output intensity that still provides an acceptable image quality. This ALARA mindset means the instrument aims for the minimum exposure needed to obtain useful diagnostic information, rather than blasting with higher power. Therefore, the output intensity is kept as low as possible. Saying it is the highest would contradict safety goals, and while modes or settings can adjust exposure, the default and overarching principle is to minimize output. Calling it moderate or variable doesn’t reflect the safety-driven aim of maintaining the lowest practical intensity.
