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.
