A type of ultrasound scan can detect cancer tissue left behind after a brain tumor is removed more sensitively than surgeons, and could improve the outcome from operations, a new study suggests. The ...

Existing defect detection tools using ultrasound rely on phased array ultrasound. In this method, many transducers are pointed in the same direction to generate an image of that specific area. This ...

A team of Caltech researchers is proposing a radical new technique for killing cancer cells using low-intensity ultrasound waves. The preliminary research is still at an incredibly early stage but ...

For decades, scientists have searched for a safe way to reach deep parts of the human brain without cutting into the skull.

Focused ultrasound from outside the body can safely and reversibly open the blood–brain barrier in patients with Alzheimer’s disease, researchers in Canada have shown for the first time. The technique ...

(a) Functional MRI maps the hand control region of the right primary motor cortex in two patients. (b, c) Gadolinium enhancement in MR images shows successful blood–brain barrier permeabilization in ...

Ultrasonography is an incredibly useful tool in medicine, particularly in emergency departments. It usually takes under a minute for an ultrasonography tool to assess whether a critically injured ...

A helmet that looks more like sports gear than surgical equipment is quietly rewriting what is possible in brain medicine. By ...
