HIFU is really a very specific kind of focused ultrasound treatment. We should start with a generic article about focused ultrasound and can link in and combine with Focused_ultrasound_for_intracranial_drug_delivery article.
I agree that this article and the Focused ultrasound for intracranial drug delivery article have quite a bit of overlap and could (and should) be separated more. Just looking at the image of the other article shows a generic image of ultrasound therapy, and nothing unique to intracranial drug delivery.
When you refer to focused ultrasound, are you referring to "FUS", which includes multiple types of ultrasound therapies, not just "HIFU"? I am not at all an expert in any of this, I only know what I've read in the small number of academic papers and online articles on the topic. Agreen991 (talk) 20:30, 24 February 2023 (UTC)[reply]
If it is solid, the vibration waves (ultrasound) can be focused, but if it is elastic, they cannot be focused because they are absorbed. This is why thick rubber sheets are used in soundproof rooms.
I agree,
I have a hard time understanding why the general heat transfer formula is written here. At one time, a non-regular teacher at the University of California, Irvine, was employed by an Indian-invented HIFU manufacturer that rented space in a nearby ultrasound inspection machine factory, and since it was written a long time ago, it may have been written at that time. It is a basic heat transfer formula that always appears on exams and is valid in solids such as iron. Applying it to HIFU is irrelevant and meaningless. It seems that there are few people on WIKI who understand engineering.
