Tokyo, September 27, 2018 — Casio Computer Co., Ltd. announced today that it will launch an English version of D’z IMAGE, its cloud-based service that enables physicians to efficiently learn about findings from dermoscopic examinations.*
- Inspection of pigmented lesions such as skin tumors and moles with a special magnification instrument called a dermatoscope.
In June 2015, Casio created D’z IMAGE, a free online cloud-based service in Japanese that gives access to dermoscopy case data, and the service has been well received. The site allows physicians to efficiently learn about findings from dermoscopic examinations* by using image analysis functions that clarify the structure of lesions and their blood vessel distribution.
Casio will now launch an English version of the site, to enable even more physicians to utilize the service. Like the Japanese version, the new English site will offer:
- Case data with findings allowing users to refer to typical cases of conditions such as malignant melanoma and basal cell carcinoma
- Diagnostic training that can deepen user knowledge for diagnosis by answering daily questions
- Image analysis tools that make it easy for users to understand the features of a lesion by converting it into an image that makes the lesion structure clear
- Learning content that uses illustrations to explain structural findings and the characteristics of colors appearing on the skin
The content of the English site will also be continually expanded.
Main Features of D’z IMAGE
Case Data with Findings
As of September 27, 2018, the site offers 1,440 case images with findings, and the number will continue to grow. The current data has been compiled with the cooperation of Dr. Yaei Togawa (Assistant Professor, Department of Dermatology, Chiba University Graduate School of Medicine), Dr. Yosuke Yamamoto (Assistant Professor, Department of Dermatology, Chiba University Hospital), Dr. Hiroshi Koga (Senior Lecturer, Department of Dermatology, Shinshu University School of Medicine), and Dr. Akane Minagawa (Assistant Professor, Department of Dermatology, Shinshu University School of Medicine). Users can refer to typical cases for conditions such as malignant melanoma, basal cell carcinoma, and seborrheic keratosis, and important parts of the images corresponding to findings can be highlighted. It is also possible to display images of manifested legions with findings, to make learning even more effective.
This function allows users to deepen their knowledge of diagnosis through repeated training based on the answering of daily questions. Each day, the physician is given a question about a case image with findings. Users can also learn by referencing images showing manifested legions, and by highlighting relevant parts of images that correspond to findings.
Image Analysis Tools
This function uses image conversion technology jointly developed by Professor Masaru Tanaka (Head of Dermatology at the Tokyo Women’s Medical University Medical Center East), Dr. Toshitsugu Sato (Director of Sato Dermatology Clinic) and Casio. When uploading an image captured during a dermoscopic examination, the site converts it into an image that makes the lesion clear and the features of the lesion easier to discern. Users can select from three types of converted images: a compositionally enhanced image that makes minute changes in a lesion clearly visible, a blood vessel enhanced image that highlights the appearance of blood vessels that are difficult to recognize with the naked eye, and a colorized blood vessel image that conforms to the fluorescent antibody method used for pathological testing of tissue specimens.
Under the supervision of Dr. Togawa, this function uses illustrations for new learners of dermoscopy about the characteristics of colors and structural findings appearing on the skin. Users can learn the basics of dermoscopy via visual images. The content is helpful for acquiring the skills of dermoscopic examination, which usually require years of experience and are difficult for new learners to acquire.
