The study could help make surgery using ultrasound techniques more precise, the physicists said.Surgeons use ultrasound to treat a range of conditions without having to cut open a patient.The ability to steer ultrasound waves to the precise spot where they are needed could make those treatments even more effective.The ultrasound waves could also be used to guide a drug capsule through the body and activate it, for instance right inside a tumour.Ultrasound waves could already be made to push objects and scientists believed they could also turn them - but the Dundee University team claims to have now proved it.
