During a sensitivity test, what is primarily measured?

• A. The camera's spatial response
• B. The degree of distortion in imaging
• C. The camera's ability to detect and respond to radiation
• D. The uniform distribution of counts

Answer: (C)

During a sensitivity test, the primary focus is on measuring the camera's ability to detect and respond to radiation. This involves evaluating how well the imaging system can sense different levels of radioactivity and its efficiency in converting that radiation into a measurable signal. High sensitivity in a nuclear medicine camera means it can capture lower levels of radioactivity effectively, which is crucial for obtaining clear and accurate images of physiological processes. Assessing sensitivity helps determine how well the imaging system will perform in clinical situations where detecting small amounts of radioactive tracers is necessary. The sensitivity of the camera directly impacts diagnostic accuracy, enabling practitioners to make informed decisions based on the images obtained during nuclear medicine procedures.
