Abstract: The neutron emission unit is configured to emit neutrons such that a center axis (Nh) of neutron emission intersects a center axis direction of collimators (23a to 23e). A calculation unit is capable of generating information about an inspection object in the center axis direction of the collimators, based on position information of the neutron detector and/or position information of the neutron emission unit, information about an angle (θ1) at which the center axis of the neutron emission intersects the center axis direction of the collimators, and a neutron amount detected by the neutron detector.

Abstract: A slit lamp microscope of an embodiment includes an image acquiring unit, a memory, and a misalignment information acquiring processor. The image acquiring unit is configured to acquire an image by applying a scan with slit light to an anterior segment of a subject's eye. The memory stores a first image of the anterior segment and a second image that is acquired by follow-up photography performed by the image acquiring unit with reference to the first image. The misalignment information acquiring processor is configured to acquire misalignment information between the first image and the second image by analyzing the first image and the second image after the follow-up photography.

Abstract: In an ophthalmic system of some embodiments, ophthalmic imaging apparatuses include slit lamp microscopes, and information processing system is connected to each ophthalmic imaging apparatus via a communication path. Each ophthalmic imaging apparatus is configured to acquire a three dimensional image by photographing a subject's eye, and transmit the three dimensional image to the information processing system. The information processing system is configured to receive the three dimensional image, store three dimensional images received, perform machine learning and/or data mining based on the three dimensional images, store knowledge acquired by the machine learning and/or data mining, and generate diagnosis support information by performing inference based on a three dimensional image of a subject's eye transmitted from one of the slit lamp microscopes knowledge stored in the knowledge storage.
