Description

Information processing device, information processing method, and recording medium Technical Field The present invention relates to an information processing apparatus, an information processing method, and a computer program. Background The radiologist uses medical images such as mammography images to determine whether or not a lesion is present. Here, the judgment of the presence or absence of a lesion or the like is carefully performed by the radiologist, but on the other hand, the radiologist may have to interpret a plurality of medical images, and there is a possibility that the lesion is ignored. For example, patent document 1 discloses a technique of calculating whether there is a risk of physical lesions or the like by computer image analysis on mammography images in which potential lesions cannot be observed with naked eyes. Prior art literature Patent literature Patent document 1 U.S. patent application publication No. 2017/0249739 specification Disclosure of Invention (Problem to be solved by the invention) For example, the manner in which the medical image is presented depends on factors such as the display used by the radiologist or the environment in which the radiologist interprets the image. And the risk of computation will also vary depending on such factors. However, the technique of patent document 1 does not consider these factors in calculating the above risk, and therefore the calculated risk deviates from the actual situation, which increases the possibility that lesions in medical images are ignored. The present invention has been made in view of such circumstances, and an object thereof is to provide an information processing apparatus, an information processing method, and a computer program capable of suppressing a situation in which lesions in medical images are ignored. (Means for solving the problems) According to the present invention, there is provided an information processing apparatus including a data acquisition unit that acquires medical image data and additional data including at least 1 of display-related data defining a presentation style of an image displayed on a display unit of a display and environment data representing an ambient environment of the display, and a data calculation unit that calculates, based on the medical image data and the additional data, omission-suppressing data that suppresses omission of lesions in the medical image data. According to the present invention, the data calculation unit can calculate data (neglect suppression data) for suppressing the lesion from being ignored in the medical image data. Since the neglect suppressing data is based on additional data including at least 1 of the display related data and the environment data, the neglect suppressing data takes the above factors into consideration, and as a result, it is possible to suppress a situation in which lesions in the medical image are ignored. Various embodiments of the present invention are illustrated below. The embodiments shown below may be combined with each other.
