Abstract: To provide an ultrasound diagnostic apparatus and a control method of the ultrasound diagnostic apparatus in which a user can smoothly perform an examination on a subject while simultaneously using a plurality of ultrasound probes. An ultrasound diagnostic apparatus includes a plurality of ultrasound probes having communication circuits that transmit synchronization signals, and operate according to a time sequence including an ultrasonic wave transmission/reception period for transmitting and receiving ultrasonic waves, a waiting period for stopping transmission and reception of the ultrasonic waves, and a synchronization period for synchronization between the ultrasound probes. In a case where any ultrasound probe is in the ultrasonic wave transmission/reception period, the other ultrasound probe is in the waiting period. In a case where any ultrasound probe is in the synchronization period, the other ultrasound probe is also in the synchronization period.

Abstract: Provided are a failure prediction system of an ultrasonic endoscope apparatus, a failure prediction method of the ultrasonic endoscope apparatus, and a non-transitory computer readable recording medium storing a failure prediction program of the ultrasonic endoscope apparatus capable of predicting a failure occurrence timing in the ultrasonic endoscope apparatus. A system controller includes an abnormality detection unit that acquires a reception signal of an ultrasonic vibrator of an ultrasonic endoscope and detects an abnormality of an ultrasonic endoscope apparatus including the ultrasonic endoscope, a storage control unit that stores information on the abnormality detected by the abnormality detection unit in association with time information, and a failure prediction unit that predicts a failure timing of the ultrasonic endoscope apparatus on the basis of the plurality of pieces of abnormality information stored by the storage control unit and time information corresponding the information.

Abstract: An endoscope has an insertion part to be inserted into a living body and an operating part. An endoscope apparatus is connected to the endoscope. The control unit displays an image associated with an operation capable of being executed by the endoscope apparatus on a part of a display screen of a display device. A visual line position detection unit detects a visual line position of an operator of the endoscope. The control unit determines whether or not the operator gazes at the image based on the visual line position detected by the visual line position detection unit. Moreover, the control unit executes the operation associated with the image based on a result of the determination and a command signal input in response to a manipulation by the operator with respect to the operating part.

Abstract: Provided are a failure diagnosis system of an ultrasonic endoscope apparatus, a failure diagnosis method of the ultrasonic endoscope apparatus, and a non-transitory computer readable recording medium storing a failure diagnosis program of the ultrasonic endoscope apparatus capable of performing failure diagnosis of the ultrasonic endoscope apparatus with high accuracy. The system controller acquires a reception signal of an ultrasonic vibrator in a state where ultrasonic waves are not transmitted from the ultrasonic vibrator of an ultrasonic endoscope, and performs failure diagnosis of an ultrasonic endoscope apparatus including the ultrasonic endoscope on the basis of the reception signal.

Abstract: A wireless tag processor includes a radio wave transmitting unit that has plural rows of transmitting part groups each having plural transmitting parts that transmit radio waves, the transmitting parts being aligned along a first direction, and the groups being provided in a second direction crossing the first direction, and that transmits radio waves to a wireless tag provided on a medium, and a control section that makes radio waves be transmitted from plural transmitting parts that is arranged staggered, among two rows of the transmitting parts included in the transmitting part groups that are adjacent to each other in the second direction crossing the first direction, and then, makes radio waves be transmitted from other transmitting parts included in the two rows of transmitting parts.

Abstract: An image of a test chart having a test pattern is taken with an electronic endoscope. A DSP of a processing device generates a test pattern image from image signals input from the electronic endoscope. An image compositor composites the test pattern image and a test mask image having a predetermined reference pattern and generates a test mask composite image. An inspector visually measures positional and rotational displacement amounts of the test pattern with respect to the reference pattern in the test mask composite image displayed on a monitor, and inputs measurement results as displacement amount information to the processing device. The displacement amount information is stored in an EEPROM of the electronic endoscope. The processing device calibrates an endoscope image of a body cavity based on the displacement amount information input from the electronic endoscope.
