    摘要: A computed radiography system including a stimulating light source such as a laser, a photostimulable glass imaging plate (PGIP) substantially transparent to the stimulating light positioned such that the stimulating light impinges the PGIP perpendicularly thereto producing photostimulated luminescence light (PLL), a light collector having a light reflecting inner surface proximate the PGIP for collecting PLL emitted from the PGIP and having a hole or slot therein for admitting stimulating light into the light collector and onto the PGIP. An optical filter in communication with the light collector for blocking stimulating light waves and passing PLL therethrough. A light detector receives PLL from the optical filter and the light collector, mechanism providing relative movement between the PGIP and the stimulating light source, and mechanism including an analog to digital converter for converting the collected and detected PLL to a diagnostic readout. The system is particularly useful in mammography.

    摘要: An inkjet printing apparatus and method of operating an inkjet printhead provides an inkjet orifice of the printhead that is located within a predetermined spacing of less than 1000 micrometers, and more preferably in a range of 50-500 micrometers for printing high resolution images. Electrical drive signals are provided to the printhead, the drive signals being adapted to enable the printhead to generate a droplet. In response to the drive signals, a free spherical droplet is formed between the orifice and a receiver member and deposits a droplet upon the receiver member substantially without presence of an attached or detached ligament of printing liquid that would otherwise provide an artifact mark on the receiver member.

    摘要: An ink jet printer capable of increasing spatial resolution of a plurality of marks to be printed thereby and method of assembling the printer. The printer comprises a print head body having a nozzle block including a plurality of adjacent ink channels of predetermined pitch "P" for printing an image on a receiver. The nozzle block is slidably disposed in the print head body and thus is movable relative to the print head body. A displacement mechanism is connected to the nozzle block for slidably moving the nozzle block a predetermined distance "P.sub.1 " less than pitch P. Before the nozzle block is moved, the channels are enabled in order to eject ink droplets which have pitch P for defining a first spatial resolution of the marks on the receiver. The displacement mechanism then moves the nozzle block the predetermined distance P.sub.1 to a second position. The channels are again enabled while the nozzle block is in this second position. Additional marks are then formed intermediate the marks formed when the nozzle block was in its first position. All the marks formed on the receiver now define a second spatial resolution greater than the first spatial resolution of the marks, so that the image has increased spatial resolution.

    摘要: An apparatus in which a plurality of developer rollers develop a latent image recorded on a flexible photoconductive member. The photoconductive belt is deflected by the developer material to wrap around at least a portion of the first two developer rollers forming wrapped development zones. The last developer roller may either have the photoconductive belt wrapped about a portion thereof, or the photoconductive belt may remain in an undeflected condition. The developer rollers having the photoconductive belt wrapped thereabout rotate in opposite directions. A blanket of developer material is formed between the last two developer rollers. An apparatus of this type optimizes development of the latent image recorded on the photoconductive member.

    摘要: Ink jet printing apparatus and method for improved accuracy of ink droplet placement on a receiver medium by compensating for jet direction variabilities between ink nozzles. More specifically, the invention is an ink jet printing apparatus and method for printing an output image on a receiver medium in response to an input image file having a plurality of pixels. The apparatus includes a print head and a nozzle integrally attached to the print head. The nozzle has a droplet placement characteristic (e.g., undesired placement of the droplet on the receiver medium) associated therewith. A waveform generator associated with the nozzle generates an electronic waveform including a plurality of electronic pulses to be supplied to the nozzle for adjusting the droplet placement characteristic. In this manner, the invention compensates for the undesired droplet placement characteristic, so that the droplet is accurately placed on the receiver medium irrespective of physical variabilities between nozzles.

    摘要: The contrast of an electrographic image or a region of interest of an electrographic image having low contrast is enhanced by developing the electrographic image with toner using a development electrode which is biased to a potential which has a value near the average potential of the image but outside of the range of values of potential corresponding to image features selected for enhancement. The voltage potential of the electrographic image is measured to determine the average potential in the region of interest. The development electrode bias is set at a potential near the average potential but outside of the range of potentials corresponding to the image features selected for enhancement in the region of interest of the image. When developed with toner, the toner image has enhanced contrast. If the image is a xeroradiographic image, diagnostic capability of low contrast regions can be enhanced.

    摘要: A radiation image storage panel includes a layer of transparent stimulable phosphor, a filter layer for strongly absorbing stimulating radiation and transmitting emitted radiation, and a radiation diffusing layer. The filter layer absorbs the beam of stimulating radiation so that an image recorded in the storage panel is not blurred by scattered stimulating radiation during readout, and the diffusing layer increases the escape efficiency of the emitted light from the storage panel.
