摘要： A digital X-ray image processing apparatus for exposing an X-ray transmitted through an object onto a photostimulable phosphor plate, for scanning the photostimulable phosphor plate by using an excitation beam to obtain an X-ray image, and for reading the X-ray image. The digital X-ray image processing apparatus includes an image storage unit for storing the X-ray image used for an actual read when diagnosing the object and a histogram storage unit for storing a standard histogram of the X-ray image. The standard histogram is formed by an intensity and frequency of the X-ray. Also provided is a first monitor unit for displaying the standard histogram read out from the histogram storage unit and a read conditions determination unit for determining actual read conditions of the X-ray image based on a latitude of the intensity of the X-ray in the standard histogram.

摘要： A digital X-ray image read apparatus having a correction function. The apparatus includes an excitation beam generation source for irradiating the excitation beam onto a photostimulable phosphor plate to generate a fluorescent light. A collection unit collects the fluorescent light of the photostimulable phosphor plate after excitation and a photomultiplier unit, connected to the collection unit, converts the fluorescent light to an analog electrical signal after multiplication. An analog-to-digital converter, connected to the photomultiplier unit, converts the analog electrical signal to a digital X-ray image signal. A correction unit, connected to the analog-to-digital converter, corrects the digital X-ray image based on a predetermined formula obtained from an amount of the fluorescent light and an afterglow thereof. An image memory connected to the correction unit, stores the X-ray image after correction.

摘要： Ultrasonic transducer having a plurality of piezoelectric elements arranged in a matrix, and a method for fabricating them. L shaped printed wiring boards are respectively bonded to each arrays of piezoelectric elements arranged in azimuthal direction. The bonding points of the L shaped printed wiring board to respective piezoelectric element are located at edge portion of respective back electrode. The other branch of L shaped printed wiring boards are stretched vertically to the surface of the piezoelectric elements matrix. A backing plate is formed by molding on the back side of the piezoelectric elements matrix leaving the top of the L shaped printed wiring board protruded from the molded surface of the molded backing plate. Such configuration prevents the reflection from the wiring plate of the piezoelectric element. A flexible printed wiring board is provided with wiring pattern having bonding areas positioned corresponding to the matrix of piezoelectric elements. So, the bonding of the printed wiring board to each of the piezoelectric element is easy. After the bonding, the printed wiring board is cut and bent vertically to the matrix surface to form the L shape. The matrix of piezoelectric elements may be cut out from a large size piezoelectric element before the molding of the backing plate or after its molding.

摘要： An ultrasonic diagnostic apparatus protected from multi-reflection of sound echoes. Multi-reflection is avoided by eliminating the reflection from the surface of an electro-sound transducer. This invention eliminates the surface reflection of the transducer by following three methods:(a) changing a direction of each surface of an array of transducer elements to direct the reflected sound wave away from the main direction of the sound beam;(b) applying an acoustic matching layer to a surface of a piezo-electric device of the transducer to cancel out phases of sound waves reflected by the surfaces of the layer and the device; and(c) providing an acoustic matching surface on a front or back face of the piezo-electric device to cancel out phases of sound waves reflected by the surface of the device.

摘要： A digital X-ray apparatus forms a latent image of an object on a photostimulable phosphor plate as an energy distribution pattern using X-ray energy and reads the latent image using an excitation light beam. A plate, of a material which does not transmit the excitation light beam, has holes formed therein with photostimulable phosphor positioned in the holes, the photostimulable phosphor emitting a fluorescent light when irradiated by the excitation light beam, the emitted light beam gathered and a corresponding signal produced. The excitation light beam reflected from the photostimulable phosphor plate is also gathered and a signal responsive thereto also is produced. A method of production by stacking and bonding plural metal sheets having appropriate patterns of holes therein with the photostimulable phosphor and a transparent protection film layer thereon provides the structure of the photostimulable phosphor plate.
