摘要： A low noise digital radiography image capture system employs a two-dimensional array of pixel sites in the image capture panel with each site having an analog-to-digital converter to digitize analog charge values produced by imaging radiation directly into corresponding digital data at the site prior to read-out to subsequent digital data processing electronics thereby avoiding noise and crosstalk problems associated with high frequency read-out of analog information. Fill factor problems caused by inclusion of integrated circuitry on the pixel site are minimized by inclusion of the A/D counter on the opposite side of the substrate support for the pixel site.

摘要： A wireless X-ray detector for a digital radiography system with remote detection of impinging radiation from the system X-ray source onto a sensor panel having amorphous or crystalline silicon photodiodes or metal insulated semiconductor (MIS) sensors. Changes in current in the photodiode bias supply circuit is sensed to generate a signal indicating presence of radiation. Improved detection of X-ray cessation is achieved either by leaving at least one line of sensors connected between the bias supply circuit to a virtual ground during charge accumulation or by using an X-ray presence detector circuit that increases the sensitivity of the detector circuit to bias circuit current changes occurring after onset of the radiation.

摘要： A wireless, independent digital imaging sensor utilizes an external charge balance capacitor to establish a sense voltage at a common node between the charge capacitor and the pixel intrinsic capacitors in the sensor panel. A variable width pulse train responds to the sense voltage to control injection of charge to the external capacitor to maintain a constant voltage at the common equal to a reference voltage. An increase in pulse width above a threshold level representative of the onset of X-ray exposure is detected to generate an output control signal used to control subsequent image acquisition functions of the imaging sensor.

摘要： A radiographic laser printer (14) has high speed memory (16) for storing digital images. The high speed memory (16) includes an array of magnetic or optical disk storage devices which are accessed in parallel from a digital data bus (12). The use of external FIFO memory is eliminated by transferring data from the data bus in interleaved format directly into buffer memories located in the disk storage devices (16).

摘要： A radiographic printer has a laser diode light source (18) which is directly modulated by an input image signal. The laser diode (18) has two operating regions, a linear laser region and a non-linear low-level light emitting region. The laser diode (18) is amplitude modulated in the lasing region and is pulse width modulated in the light emitting region. A programmable digital delay (60) produces the pulse width modulating signal and a digital comparator (34) determines whether the laser diode operates in the amplitude modulation mode or the pulse width modulation mode. A current steering circuit (44), (46), (48), (50) is used in the pulse width modulation mode to rapidly switch the diode on and off. In addition, programmable digital to analog converters (56), (58) are used to compensate for changes in different diode slope efficiencies and threshold currents.
