A radiation imaging system is provided. The radiation imaging system comprises an irradiation control apparatus configured to control a timing of radiation irradiation by a radiation generating apparatus and a radiation imaging apparatus configured to communicate by at least one synchronous communication method to synchronize with the radiation irradiation. The irradiation control apparatus comprises a determination unit configured to determine an imaging mode that has been set and a synchronous communication method which can be supported by the radiation imaging apparatus, and a control unit configured to control, based on the determination result, the timing of the radiation irradiation by a synchronous communication method corresponding to the imaging mode.

Radiation imaging system, radiation control apparatus and method of controlling radiation imaging system

An image processing apparatus includes a communication interface and a controller. The communication interface is configured to acquire a first video image capturing an outside area of a moving body. The controller is configured to cause a second video image corresponding to a display region of the first video image to be displayed on a display apparatus. The controller is also configured to detect at least a portion of a detection object in the display region of the first video image, determine whether one or more conditions are met based on a relative positional relationship between the moving body and the detection object and, when it is determined that the one or more conditions are met, cause a first marker corresponding to the detection object to be superimposed on the second video image and displayed on the display apparatus.

Image processing apparatus

An imaging apparatus includes a converter configured to convert an analog signal obtained from detected interference light into a digital signal and a clock generator configured as an interferometer including an optical path through which part of light emitted from a light source passes, the optical path being split into a first optical path and a second optical path having an optical path length difference therebetween, to generate a clock used by the converter sampling the analog signal at a frequency corresponding to the optical path length difference. The converter includes n A/D converters, n being an integer of at least 2, and is configured to change phases of n clocks obtained from the clock to produce a phase difference therebetween, and to generate a clock having an n-times frequency from the n clocks and n analog signals obtained from the analog signal using the n A/D converters.

Imaging apparatus

An SS-OCT apparatus includes a clock generator configured as an interferometer including an optical path through which part of light emitted from a light source passes, the optical path being split into a first optical path and a second optical path having an optical path length difference relative to the first optical path, to generate a clock used by a converter sampling an analog signal; a tomographic image obtaining unit configured to obtain a tomographic image of a fundus by using a digital signal converted from the analog signal sampled by the converter using the generated clock; and a scan unit configured to scan illumination light across the fundus at a scan angle of 47 degrees or more in air. The tomographic image obtaining unit is configured to obtain a tomographic image of the fundus at a distance of 4.0 mm more within an eyeball in a depth range.
