High Frequency Ultrasound for High Resolution Skin Imaging

Abstract: High frequency and broadband ultrasound in the frequency range above 20 MHz is an efficient modality for the non invasive and high resolution imaging of skin structures and skin diseases like skin tumors and inflammatory processes. However, special system designs and signal processing strategies have to be applied to account for the strong and frequency dependent attenuation of high frequency ultrasound in tissue. In this paper the design of an ultrasound imaging system with a minimum spatial resolution of abo… Show more

“…Furthermore, a much finer echo texture is visible in the dermis, which indicates the better spatial resolution as well. In dermatological diagnostics, skin lesions are of great relevance 13,16,18 . Established 20MHz range sonography is so far mainly applied to non invasively measuring the depth of lesion penetration into healthy skin tissue for surgery planning.…”

“…While the advantage of standard 20 MHz sonography is the capability to image the whole skin, spatial resolution is relatively poor. Utilizing higher frequencies and increasing the bandwidth, resolution can significantly be improved while the penetration depth decreases at the same time because of the frequency dependent attenuation [13][14][15][16] . High resolution imaging of the uppermost skin layers is especially of interest with respect to skin lesion investigations.…”
