Plane wave imaging challenge [PDF]
2016 IEEE International Ultrasonics Symposium (IUS), 2016 The plane wave imaging challenge(PICMUS) has been introduced for the first time to IUS in order to encourage participants to compete and share their knowledge in medical ultrasound plane wave imaging. To participate in this challenge, we have chosen the contrast enhanced delay and sum (CEDAS) post signal processing method. This technique have been used

Omega-K Algorithm Using Plane Wave Approximation for Forward-Looking Imaging Radar [PDF]
Journal of Electromagnetic Engineering and Science, 2022 We propose an Omega-K algorithm that uses plane wave approximation for image formation in forward-looking imaging radar (FIRA) with the multi-input/double-output configuration.

A Radon diffraction theorem for plane wave ultrasound imaging
The Journal of the Acoustical Society of America, 2023 The rising demand on high frame rate ultrasound imaging applications necessitates the development of fast algorithms for plane wave image reconstruction. We introduce a new class of plane wave reconstructions that relies on a relation between receive data and image data in the Radon domain.
