Conventional ultrasound (cUS) and functional ultrasound (fUS) both utilize megahertz-level sound waves to image inside the body; however, beyond this, the similarities end. This article aims to ...
A team develops an ultrasensitive broadband transparent ultrasound transducer. The 'ultrasound-photoacoustic dual-modal imaging system' combines molecular imaging contrast with ultrasound imaging, and ...
