Abstract |

内容記述 |
Ultrasound diagnostic equipment, with the high number of facilities equipped with and engineers handling it and its minimal effects on the body, represents a convenient means of examination. It can also be an effective tool for making the first diagnosis for some visceral diseases. However, excepting ultrasound diagnostic equipment hardware, image diagnostic technology research remains confined to relatively narrow areas such as three-dimensionality, elastography, and breast cancer diagnosis. Its versatile and broadly applicable nature is not being sufficiently exploited. This study, taking as an example of widely applicable assisted diagnosis technology, the assisted diagnosis of hepatic regional disorders was demonstrated an expert system-type method that calculates the image's statistical primary features, assigns weights based on experience and obtains averages, and then outputs confidence levels for the three disorders of liver cirrhosis, fatty liver, and cysts. This method in essence quantifies and indicates the presence or absence of disease in terms of confidence level. Evaluation was performed with images from 12 patients. The method produced results that were approximately consistent with a physician's judgment for all of the images. Compared to the conventional physician-conducted method, advantages are evident in the new method's quantification capability, its reproducibility, and its standardization capability as enabled by its ability to reduce the effects of diagnostic equipment setup, composition, speckle noise, and other factors affecting judgment. Furthermore, analysis of results indicated that, because a high correlation between primary features and physician's judgment was obtained, enabling easy analysis and tracking of judgment details, validity can be justified. |
