A printing method comprising: forming a first image utilizing a liquid toner comprising carrier liquid and pigmented polymer particles having a first color; transferring the first image to an intermediate transfer member; forming at least one additional image utilizing a liquid toner comprising at least one carrier liquid and pigmented polymer particles having a second color, different from the first color; transferring the at least one additional image to the intermediate transfer member overlaid on the first image, to form a composite image on the intermediate transfer member; and further transferring the composite image to a further substrate, wherein said polymer particles in said first liquid toner and in at least one of said additional liquid toners have different compositions, aside from colorants, the differences in composition including at least one of different polymers or blends of polymers, different amounts or types of placticizers, different amounts of solvated liquid and different compositions of solvated liquid.
摘要:
A multicolor electrostatic imaging system includes an electrostatic imaging surface, apparatus for supplying an electrostatic image on the electrostatic image surface, and multicolor supply apparatus for supplying a liquid toner of a selectable color to the electrostatic imaging surface. The supply apparatus has a multiplicity of jet outlets, including a set of jet outlets for supplying toner of the selectable color directly to the imaging surface, the set of jet outlets being distributed among the multiplicity of jet outlets. Finally, developing apparatus is provided for developing the electrostatic image using the liquid toner, and transfer apparatus is provided for transferring the developed image to a substrate.
摘要:
Apparatus for image transfer including an image bearing surface arranged to support a liquid toner image thereon, including image regions and background regions ,rigidizing means for rigidizing the toner image at the image regions, and squeegee means separate from the rigidizing means for removing excess liquid from the toner image after rigidization thereof, prior to transfer of the image to a substrate.
摘要:
Improved diagnostic imaging methods and systems for automatically controlling variable parameters used when translating detected radiation intensities caused by radiation that has passed through an object and impinged on a detector to fixed values for display images by determining the maximum and minimum intensities at the impinged on detector locations and adjusting the parameters as functions of the said maximum and minimum intensities.
摘要:
A method of imaging a patient is provided. The method includes coupling at least one detector to a detector transport member such that the at least one detector moves with the detector transport member and the detector transport member spans an arc of less than about one hundred eighty degrees about an examination axis, supporting the detector transport member through an arcuate base having an arcuate support assembly for receiving the detector transport member, and rotating the detector transport member about the examination axis to a plurality of imaging positions.
摘要:
Apparatus for enhancement of image transfer including an image bearing surface and a second surface arranged for relative movement along a pathway whereby portions of the image bearing surface and the second surface sequentially come into propinquity and subsequently move out of propinquity, potential impression means associated with at least one portion of at least one of the image bearing surface and the second surface for impressing a potential on the at least one portion, and means for energizing the potential impression means only when such portions are located at predetermined locations along the pathway, thereby to provide image rigidization.
摘要:
A method of quantitatively determining the stenosis of the blood vessel using a digital subtraction angiographic image of the blood vessel. The method includes obtaining numbers proportional to the cross sectional areas of the blood vessel at stenosis portions and normal portions by obtaining density profiles less residual background from the images at those portions.
摘要:
Image enhancement accomplished by filtering using filters optimally adjusted to system parameters to enhance long edges, attenuate noise and "points" so that the long-edge data normally buried in noise is available and to further enable using low-frequency data.
摘要:
A misregistration correction system that corrects for artifacts generated by the movement of a subject being imaged during the interval between temporally separated images. The system reduces the effects of secondary characteristics on the determination of a vector between a point on a first image and a point on a second image, which vector delineates the motion of the subject.
