Abstract

A computerized system was developed to carry out the clinical diagnosis of cutaneous melanoma. The main objective of the system is to produce a real-time first level diagnosis of skin lesion images acquired by a color TV camera. The algorithms are based on research activities started in 1985 at the National Cancer Institute of Milan. Color slides of skin lesions were used as a training field for studying and tuning the image analysis procedures. A prototype system was then developed to capture and analyze skin lesion images on a real-time basis. More than 200 images were acquired and the first level diagnosis output by the system was compared with the diagnosis of expert clinicians. The obtained results were judged very encouraging by the clinicians, and research is in progress to improve and refine the system. The diagnostic procedure is based on image processing and understanding techniques, automatic lesion contour recognition, feature extraction (feature components derived from lesion shape, color and texture) and computation of a malignancy index. The malignancy index depends on the lesion feature values and a thesaurus collecting the system knowledge; the histologic results of clinically diagnosed malignant lesions are used to upgrade the system knowledge.
