Early diagnosis of skin cancer by ultrasound frequency analysis

High-Frequency Ultrasound Examination in the Diagnosis of Skin Cancer.

Ultrasound above 14 MHz images epidermis, dermis, and subcutaneous tissues in real time. Tumor depth is ascertained with B-mode. Three-dimensional imaging depicts nonpalpable, in-transit, and satellite lesions. Doppler blood flow technologies measure tumor neovascularity and map vascular structures. Three-dimensional Doppler histogram reconstruction measures tumor aggression and metastatic pote...

Assessment of the diagnostic capability of ultrasound in early diagnosis of nephrolithiasis: a feasibility study

Towards Prevention and Early Diagnosis of Skin Cancer: Computer-aided Analysis of Dermoscopy Images

Melanoma, the deadliest form of skin cancer, must be diagnosed early for effective treatment. Irregular pigment network and streaks are important clues for melanoma diagnosis using dermoscopy images. This thesis describes novel image processing approaches for computer-aided pigment network and streaks detection on dermoscopy images. Our methods provide meaningful visualization of these structur...
