He has made significant contributions to the field of ultrasound imaging, holding three patents that showcase his innovative approach to technology. His work has implications for medical imaging and diagnostics, enhancing the capabilities of ultrasound technology.

Latest Patents

One of his latest patents is an acoustic coupler and ultrasound imaging method. This invention provides an acoustic coupler capable of achieving both low elastic modulus and high deformability required for ultrasound imaging. The acoustic coupler is strategically placed between a probe for transmitting ultrasound waves and a subject. It comprises a hydrogel that includes a copolymer containing water. The copolymer consists of a monofunctional monomer with one ethylenically unsaturated group and a polyfunctional monomer with two to six ethylenically unsaturated groups. The molar ratio of the monofunctional monomer to the polyfunctional monomer is more than 90 and less than or equal to 3500. Another significant patent is for an ultrasound imaging apparatus. In this invention, a laser beam is applied to a photoacoustic wave generation source multiple times during the reception period of ultrasound waves. This process generates multiple photoacoustic waves, which are then received by a reception unit of the ultrasound imaging apparatus. The positions of these waves on a time axis are adjusted, and the waves are averaged to generate a photoacoustic image based on the obtained signal.
