Abstract: A storage device of an ophthalmologic image display device of an embodiment stores a three dimensional data set acquired by scanning a subject's eye using OCT. An image processor forms, based on the three dimensional data set, a B-mode image, front images, and composite front image obtained from the front images. A display controller displays the B-mode image, front images and composite front image in a predetermined layout. The display controller displays distinguishment color information for distinguishment between the front images by colors and slice area information that indicates a partial region of the B-mode image corresponding to a slice area of the three dimensional data set represented by each front image in a color according to the distinguishment color information, and displays a composite front image based on the front images, each of which is expressed by a color according to the distinguishment color information.

Abstract: A blood flow measuring unit of a blood flow measurement apparatus of an embodiment includes an optical system for applying an OCT scan to an eye fundus and obtains blood flow information based on data acquired by the OCT scan. A movement mechanism moves the optical system. A controller applies a first movement control to the movement mechanism to move the optical system in a first direction orthogonal to an optical axis of the optical system by a predetermined distance from the optical axis. A judging unit judges occurrence of vignetting based on a detection result of return light of light incident on the eye through the optical system after the first movement control. The controller applies a second movement control to the movement mechanism to further move the optical system based on a judgement result obtained by the judging unit.

Abstract: A sputtering device capable of satisfying various requirements is provided. The sputtering device includes a rotation and revolution table, multiple sputtering targets, an RF plasma source, and a load-lock chamber 102. The rotation and revolution table is arranged inside a pressure-reducible container 101 and is rotatable by independent control. The multiple sputtering targets are arranged on a revolution orbit of the rotation and revolution table so as to correspond to multiple workpieces 107 to be set on the rotation and revolution table. The RF plasma source performs plasma treatment. The load-lock chamber 102 is used for setting the multiple workpieces on the rotation and revolution table. The rotation and revolution table is configured by arranging multiple rotation mounts 105 on a revolution table 104, and the rotations of the revolution table 104 and the multiple rotation mounts 105 are independently controllable.

Abstract: A blood flow measurement apparatus of an aspect example includes a scanning optical system, a front image acquiring unit, a region-of-interest determining processor, a scan controller, and a blood flow information acquiring unit. The scanning optical system applies OCT scanning to a fundus of a subject's eye. The front image acquiring unit acquires a front image of the fundus. The region-of-interest determining processor determines a region of interest that intersects a blood vessel by analyzing the front image based on a condition set in advance. The scan controller controls the scanning optical system to apply a repetitive OCT scan to the region of interest. The blood flow information acquiring unit acquires blood flow information based on data collected by the repetitive OCT scan.
