Final answer:
The true statement regarding decreased frame rate is that increased line density will lead to a decreased frame rate. Higher frame rates, not lower, are preferred for real-time 2D imaging and improving temporal resolution in ultrasound technology.
Step-by-step explanation:
The true statement regarding decreased frame rate is: D) Increased line density will lead to a decreased frame rate.
Decreased frame rates can affect various aspects of ultrasound imaging. To elaborate:
- A) Decreasing frame rates will not improve color Doppler evaluation. Higher frame rates are typically preferred because they provide more real-time information and better temporal resolution.
- B) Decreased frame rates are not preferred for real-time 2D imaging because real-time imaging requires a higher frame rate for better visualization of moving structures.
- C) Decreased frame rates will not improve temporal resolution; in fact, the opposite is true. Higher frame rates improve temporal resolution, which is the ability to accurately detect changes in the image over time.
- The correct answer is D), as increased line density means more lines are scanned per frame, which takes longer and thus reduces the frame rate.
