A question about ultrasound

We do ultrasound of the heart with a probe which is smaller than other probes but it is still wider than the spaces in between the ribs. How do we see a good picture of heart without any interference of the ribs. Perhaps we should see bands of ribs and in between the bands the heart itself. thanks

I am not 100% sure but...

I think the key point might that it is an ultrasound scan.
The ultrasound pulses are actually focused and this focus point is scanned across the region of interest.
I suspect also that the timing between emitting the pulse and receiving the reflection
is used to determine the depth of field of the image, thus allowing intervening structures (like ribs) to be ignored.

But I think ribs will block the passage of ultrasound?

I have actually had an ultrasound heart scan,
(they found nothing wrong thankfully)

It was some time ago and my memory is a bit blurry,
but as I remember they scanned from beneath the ribs pointing up.

So I guess you may be correct that the ribs might distort the image.

I do heart ultrasound myself, We do scan from stomach(from beneath the ribs) too but most of the scan is done while rib cage is between the probe and heart.
