Patent number: 7186997Abstract: A device and a method for reading out information stored in a storage layer (15), and an X-ray cassette are proposed which make use for the purpose of erasing information stored in the storage layer (15) of an erasing means (11, 12, 14) which generates an erasure radiation (17). This erasure radiation (17) can have both a first and a second intensity, the first intensity being larger than the second intensity.Type: GrantFiled: December 16, 2000Date of Patent: March 6, 2007Assignee: Agfa-Gevaert HealthCare GmbHInventors: Herbert Gebele, Jurgen Muller, Hans Schaller, Werner Stahl

Patent number: 7170079Abstract: The invention relates to a method of reading out information items stored in a phosphor layer, in which the phosphor layer is excited to emit emission light and the emission light is sensed by a detector and the detector is moved relative to the phosphor layer. During this process, the detector consecutively senses the emission light emitted in each case by individual regions of the phosphor layer. To reduce the dark noise and the movement blur, provision is made that the detector senses the emission light emitted by a region during an integration time that is less than a forward-travel time for the movement of the detector by the width of the region in the forward-travel direction (V).Type: GrantFiled: August 11, 2004Date of Patent: January 30, 2007Assignee: Agfa-Gevaert HealthCare GmbHInventors: Robert Fasbender, Herbert Gebele, Michael Weinberger

Patent number: 7109496Abstract: The invention relates to a storage layer (4) for storing x-ray information, comprising a large number of needle-shaped storage material areas (15A to 15L) for guiding light radiation (17 to 28, 30 to 35). An absorption zone (14A to 14N), which contains absorption material for absorbing light radiation (17 to 23, 30 to 35, 39) lies between the individual needle-shaped storage material areas (15A to 15L) and absorbs less than all of the light radiation that it receives. The invention also relates to a device for reading x-ray information from a storage layer of this type and to an x-ray cassette which has a device of this type for reading x-ray information.Type: GrantFiled: November 27, 2001Date of Patent: September 19, 2006Assignee: Agfa-Gevaert Healthcare GmbHInventors: Herbert Gebele, Hans Schaller, Robert Fasbender

Patent number: 6858861Abstract: An apparatus for reading information stored in a memory phosphor has a detecting device with an array of radiation-sensitive surface segments which during a pre-settable integration time interval receive a secondary radiation emitted by the memory phosphor. The apparatus includes a controller device that sets the integration time interval dependent on an amount of secondary radiation that was received at a preceding time. The controller device can also connect the radiation-sensitive surface segments into groups whose size depends on the amount of secondary radiation that was received at a preceding time.Type: GrantFiled: December 3, 2002Date of Patent: February 22, 2005Assignee: Agfa-Gevaert AktiengesellschaftInventors: Herbert Gebele, Jurgen Muller, Robert Fasbender

Patent number: 6369402Abstract: A device (1) and a method for reading information stored in a phosphor layer (10) is disclosed. The device (1) includes a transparent carrier material (9) on which the phosphor layer (10) to be read is disposed. A radiation source (2) emits an excitation radiation (20) to excite the phosphor layer (10), which in turn emits an emission radiation (26). The emission radiation (26) can be received by a receiver (3). The radiation source (2) is arranged on one side of the transparent carrier material (9), whereas the receiver (3) is arranged on the other side of the transparent carrier material (9), thereby defining an optical path between the radiation source (2) and the receiver (3). According to the invention, a reflective layer (21, 22; 30, 31, 32) for reflecting at least a portion of the excitation radiation (20) is arranged in the optical path.Type: GrantFiled: November 30, 1999Date of Patent: April 9, 2002Assignee: Agfa-Gevaert AGInventors: Herbert Gebele, Paul Leblans, Jürgen Müller, Ralph Thoma

Patent number: 4791282Abstract: An X-ray film cassette has on its top a triangular bar code field readable by a bar code reader of an automatic film sheet charging and discharging apparatus. The bar code field is in the form of an isosceles right triangle whose hypothenuse faces a reference corner and whose legs extend parallel to edges of the cassettes. The bars of the code extend parallel to the hypothenuse. An optical axis of the bar code reader, when the cassette is in its end position in the apparatus, intersects a vertex area formed by the legs of the triangle. This arrangement guarantees that its bar codes on cassettes of small format, even if misaligned in the feeding direction, are reliably read by the reader.Type: GrantFiled: September 11, 1986Date of Patent: December 13, 1988Assignee: AGFA- GEVAERT AGInventors: Manfred Schmidt, Herbert Gebele

Patent number: 4783588Abstract: An apparatus for automatic charging and discharging an X-ray film sheet into a cassette includes a bar code reader having an illumination device and a rotary scanning mirror. The cassette is provided on its top with a bar code label which irrespective of the format of the cassette is always located at a fixed distance from a leading edge and from a lateral guiding edge of the cassette. The cassette is insertable into an intake compartment and only after the cassette reaches an end position in the compartment a limit switch activates the scanning mirror and the illumination device of the reader, thus eliminating reading errors when reading bar codes on cassettes of different formats.Type: GrantFiled: September 11, 1986Date of Patent: November 8, 1988Assignee: AGFA-Gevaert AGInventors: Manfred Schmidt, Herbert Gebele
