Abstract :
High frequency, broadband ultrasound providing high resolution is found to satisfy several clinical and diagnostic requirements in dermatology. The imaging procedure with strongly focused single element transducers can be optimized by application of a modified scan concept (B/D-Scan concept, “brightness/depth”). Furthermore, texture features and attenuation estimates can be obtained from the echo data with appropriate procedures in order to differentiate tissue layers, skin appendix structures and pathologic changes. Results from these procedures are discussed and parameter images are presented
