40-MHz Ultrasound Imaging with Chirps and Annular Arrays

High-frequency ultrasound (HFU) shows promise for fine-resolution imaging. However, the depth of field (DOF) and penetration depth of HFU waves limit clinical significance. In a previous study using a 17-MHz annular array, we established that chirp coded excitation and synthetic focusing can improve...
