Point of Care Ultrasound (POCUS) Real-Time 3D or Multi-Plane 2D Ultrasound Imaging Based on Bessel or Focused Beam Steered by a Reflector Driven by Electromagnets or Micro-Motors

Project ID: TECH-2025-34 Background: Despite that there are many companies that develop POCUS devices, many have so many problems with good images, short battery life, heating issues and no 3D images. Traditionally, a one-dimensional (1D) array transducer is used for two-dimensional (2D) imaging, where the transducer and its cable are heavy and bulky,...

Super Resolution Imaging with Modulation of Point Spread Function

Project ID: TECH2024-09 Background High image resolution is a desired outcome in wave-related disciplines such as ultrasound, acoustics, optics, and electromagnetics. However, the spatial resolution of an imaging system is fundamentally limited by the spatial frequency of the point spread function (PSF) of the system due to diffraction. There have...
