Clinical Application of Ultra-High-Frequency Ultrasound. [PDF]

J Pers Med, 2022
Musculoskeletal ultrasound involves the study of many superficial targets, especially in the hands, wrists, and feet. Many of these areas are within the first 3 cm of the skin surface and are ideal targets for ultra-high-frequency ultrasound. The high spatial resolution and the superb image quality achievable allow foreseeing a wider use of this novel ...

Prurigo Nodularis at Ultra-High-Frequency Ultrasound [PDF]

Diagnostics
Here, we describe the case of a 48-year-old female patient with prurigo nodularis, where B-mode and color-Doppler ultrasound of one nodule was performed; this revealed hypoechoic dermal and hyperechoic epidermal thickening with lesion hypervascularity ...

Bandwidth limitations of ultra high frequency–radio frequency identification tags [PDF]

IET Microwaves, Antennas & Propagation, 2013
Fundamental bandwidth limitations on the design of ultra high frequency (UHF) radio frequency identification (RFID) tags are investigated. This study was conducted by considering the optimum equivalent‐circuit network necessary for bandwidth broadening in single resonant UHF–RFID tags with conjugate matching.
