1. Which mechanism is primarily responsible for volume acquisition in 3D ultrasound transducers?
Electronic beam steering A mechanically moved transducer element A phased array sweep Manual transducer oscillation by the operator
2. Which three transducer types are used for 3D volume acquisition in obstetric and gynecological imaging?
Phased array, annular array, and vector Linear, convex, and transvaginal Curved, micro-convex, and hockey stick Linear, phased array, and transvaginal
3. What is the stated advantage of 3D volume data over conventional 2D cine-loop or video recording?
3D acquisition is faster to perform 3D volume data is superior to 2D video/cine-loop in the information it provides 3D reduces acoustic exposure 3D eliminates the need for operator skill
4. During 3D volume acquisition, what two conditions must be maintained simultaneously once the region of interest is reached?
The operator must angle the transducer and the patient must breathe shallowly The operator must keep the transducer stable and the patient must remain still The operator must sweep manually while the patient holds their breath The patient must move slightly to expose all planes
5. After 3D volume acquisition, what process produces the three-dimensional display from the captured images?
The operator manually aligns the 2D frames The images are sent to a remote workstation for offline processing A computer processes the acquired images & reconstructs them three-dimensionally The transducer directly generates a 3D image without post-processing
6. In multiplanar volume mode, which anatomical plane does the A-plane represent?
Transverse Coronal Longitudinal or sagittal Oblique
7. Around how many axes can a reconstructed 3D volume be rotated in multiplanar mode for comprehensive anatomical evaluation?
One axis only (Z-axis) Two axes (X and Y) Three axes — X, Y, and Z Rotation is not possible in multiplanar mode
