Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a new ultrasound device that produces sharper images through 3D printed lenses.
With clearer images, doctors and surgeons can have greater control and precision when performing non-invasive diagnostic procedures and medical surgeries. The new device will allow for more accurate medical procedures that involve the use of ultrasound to kill tumors, loosen blood clots and deliver drugs into targeted cells.
The ultrasound device is equipped with superior resin lenses that have been 3D printed. In current ultrasound machines, the lens which focuses the ultrasound waves are limited to cylindrical or spherical shapes, restricting the clarity of the imaging.
With 3D printing, complex lens shapes can be made which results in sharper images. The 3D printed lenses allow ultrasound waves to be focused at multiple sites or shape the focus specially to a target, which current ultrasound machines are unable to do.
