摘要: An image read-out and reproducing apparatus comprises an acousto-optic modulator, and a change-over device for guiding zero-order light and first-order light radiated by the acousto-optic modulator to a predetermined optical path. A deflector deflects a light beam to scan an image-recorded image information sheet or a recording sheet in a main scanning direction, and a sub-scanning device moves the image information sheet or the recording sheet normal to the main scanning direction. When the image information sheet is moved by the sub-scanning device, zero-order light is guided by the change-over device to the predetermined optical path and deflected to scan the image information sheet, thereby to carry out image read-out from the image information sheet. When the recording sheet is moved by the sub-scanning device, first-order light is guided by the change-over device to the predetermined optical path, modulated in accordance with image signals and deflected to scan the recording sheet, thereby to reproduce the image on the recording sheet.

摘要: N numbers of ultrasonic transducers are arranged at a tip of an ultrasonic probe. A wire from each transducer is connected to a multiplexer (MUX). The MUX selectively switches M numbers of the ultrasonic transducers to be driven out of the N numbers of the ultrasonic transducers. A short-circuit switch is connected to each of the ultrasonic transducers. The short-circuit switches short-circuit adjacent L numbers of the ultrasonic transducers, and simultaneously drive the L numbers of the ultrasonic transducers as a single ultrasonic transducer. A CPU changes the number L in accordance with the frequency band of the ultrasonic waves which is set by an operation unit.

摘要: An image signal representing radiation image information on an object stored on a stimulable phosphor sheet is read out by scanning the stimulable phosphor sheet with a stimulating light beam and photoelectrically detecting light emitted from the stimulable phosphor sheet upon stimulation thereof by a photodetector having a photoelectric surface. A variable transmittance medium whose transmittance to the light emitted from the stimulable phosphor sheet upon stimulation thereof is variable continuously or stepwise is inserted into the optical path of the light between the stimulable phosphor sheet and the photoelectric surface of the photodetector The transmittance of the variable transmittance medium is changed according to the amount of light emitted from the stimulable phosphor sheet upon stimulation thereof so that the photoelectric surface is not saturated by an excessive amount of light impinging thereupon.
