Which transducer type was used to create the TV image of the uterus?

• A. Linear array
• B. Phased array
• C. Single-element mechanical
• D. Tightly curved array

Answer: (D)

For TV (real-time) imaging of the uterus, the transducer needs to be placed close to the uterus with high-resolution detail in the shallow pelvic space. An endocavitary transducer that is tightly curved has a small footprint and a curved emitting surface, which concentrates the beam and focuses it for shallow depths. This design provides excellent near-field resolution and a wide, sweepable field of view ideal for pelvic organs like the uterus. The flat surface of a linear array is better for superficial structures but isn’t optimal for deep pelvic access; phased arrays are great for cardiac windows but aren’t the typical choice for endovaginal imaging; a single-element mechanical transducer is bulky and slower, not ideal for real-time TV imaging. So the tightly curved array transducer fits best for creating a TV image of the uterus.
