The ultrasound image provided shows the liver and diaphragm imaged in a coronal plane with characteristic rib shadows and costophrenic angles. The orientation of the image and the structures visualized suggest that the transducer is placed in the right mid-axillary line, with the sound beam directed coronally — this is a classic right coronal scanning approach.
Key features supporting this:
The liver appears superiorly in the image.
Multiple echogenic lines (representing the ribs) run obliquely, casting acoustic shadows.
The diaphragm and adjacent lung base are seen clearly, which is commonly imaged through the right intercostal spaces in a coronal plane.
Comparison of answer choices:
A. Anterior: Would show a more transverse view of the liver and not typically image the diaphragm and lung this way.
B. Posterior: Not used for upper abdominal scanning due to shadowing from the spine and posterior ribs.
C. Left coronal: Would show the spleen and left kidney — not the liver as seen here.
D. Right coronal — Correct. This image was obtained using the right coronal (intercostal) approach through the right flank.
