Sound scan showdown
Whole cross-sectional human ultrasound tomography
A giant sound ring could scan your whole body—and the comments are already spiraling
TLDR: Researchers say they can now use a ring-shaped ultrasound system to capture full-body slices and help with things like fat measurement and needle guidance. Commenters were less calm than the paper, immediately connecting it to Midjourney, swapping links, and debating whether this is a medical breakthrough or a startup-origin drama thread.
Scientists have unveiled a new ultrasound setup that can make full cross-section pictures of the human body—think a whole slice of your abdomen or thigh at once, instead of the smaller, probe-by-probe views doctors usually get today. The big promise? Seeing body fat patterns without radiation, and even helping track biopsy needles in real time. In plain English: a less squishy, less operator-dependent way to look inside you using sound.
But the real action was in the comments, where readers instantly turned this into a "wait, is this that Midjourney thing?" detective story. One commenter pointed straight at Midjourney’s medical post, while another jumped in with a Caltech explainer, basically saying, “Receipts, people.” Then came the tech wonk energy: one reader claimed this research is basically the origin story for Midjourney’s much-hyped scanner and started unpacking why scanning through a big water tank over long distances is a very different beast from a normal ultrasound wand.
Not all the reactions were hard science. One commenter dropped the thread’s accidental dad joke of the day, lamenting they’d wanted a career in tomography but just couldn’t find the right elective lane. That gave the whole discussion a wonderfully nerdy, slightly chaotic vibe: part breakthrough buzz, part startup sleuthing, part “missed my calling.” The mood? Curious, impressed, and just suspicious enough to keep the drama delicious.
Key Points
- •The article presents a whole cross-sectional human ultrasound tomography system for in vivo imaging in both reflection and transmission modes.
- •The system uses a custom 512-element circular ultrasound receiver array and a rotating transmitter to image full cross-sections of the abdomen and thighs.
- •The authors report uniform in-plane resolution across the imaged cross-section.
- •Sequential scans from the system showed strong agreement with corresponding clinical MRI images.
- •The article highlights two applications: assessing abdominal adipose thickness without ionising radiation or mechanical deformation, and video-rate localization of biopsy needles relative to tissue features.
