Final answer:
Spatial compounding offers better visualization of fibroids by increasing penetration far field and resolution.The correct option is B.
Step-by-step explanation:
In order to visualize fibroids better by increasing penetration far field and resolution, spatial compounding would be a better control option.
Spatial compounding involves using multiple ultrasound beams and images from different angles to create a single composite image. This technique improves image quality and reduces artifacts, resulting in enhanced visualization of fibroids.
On the other hand, persistence is a control option that maintains previously acquired images and overlays them on the current imaging frame, providing temporal averaging and reducing noise, but it does not specifically enhance penetration or resolution for fibroid visualization.
Coded excitation is a technique used to improve signal-to-noise ratio and penetration, but it does not directly relate to visualization of fibroids.
Elastography is a technique used to assess tissue elasticity and stiffness, but it is not primarily focused on improving fibroid visualization.The correct option is B.
