Patent number: 8265226Abstract: The present invention relates to an X-ray image acquiring apparatus having a structure for improving the quality of an image signal representing an X-ray image captured. The X-ray image acquiring apparatus (5) comprises an imaging section (7), a connecting section (8), and a signal cable (L1). The imaging section (7) outputs an image signal representing an X-ray image captured. The connecting section (8) has a structure attachable/detachable to a control circuit (6) for controlling the imaging section (7). The signal cable (L1) has one end connected to the imaging section (7) and the other end connected to the connecting section (8), and is flexible. The signal cable (L1) includes a detection signal line (L11), a control signal line (L12), an image signal line (L13), and a GND line (L14), which are used for transmitting signals exchanged between the imaging section (7) and the control circuit (6), and a shield member (5a) covering these lines (L11 to L14).Type: GrantFiled: November 11, 2008Date of Patent: September 11, 2012Assignee: Hamamatsu Photonics K.K.Inventors: Akira Taoka, Kazuhisa Miyaguchi

Patent number: 7676024Abstract: An apparatus includes: an imaging unit 7, an X-ray detecting unit 90, outputting, upon irradiation of X-rays, an X-ray detection signal over the irradiation period; an operation controlling unit 13, generating a trigger indicating an imaging start timing based on the X-ray detection signal and using the trigger to perform operation controlling of the imaging unit 7; and a signal cable L1, containing, within a tube 11, one or a plurality of each of a detection signal line L11, transmitting the X-ray detection signal, a controlling signal line L12, transmitting a controlling signal for drive control of the imaging unit 7, and an image signal line L13, transmitting image signals, resulting from imaging by the imaging unit 7, and in the signal cable L1, the detection signal line L11 is disposed at an inner central portion of the tube 11 and the other signal lines are disposed so as to surround the detection signal line L11. The occurrence of malfunctions in the X-ray imaging apparatus is thereby reduced.Type: GrantFiled: March 7, 2006Date of Patent: March 9, 2010Assignee: Hamamatsu Photonics K.K.Inventors: Akira Taoka, Kazuhisa Miyaguchi

Patent number: 7573979Abstract: When a signal S2 with a pulse width corresponding to an entire X-ray irradiation period is input, a pulse P3 (signal S5) with a predetermined pulse width is output at an input timing of the signal S2, and when a new signal S2 is input during output of the pulse P3, the pulse P3, being output, is extendingly output further for the above pulse width from the input timing of the signal S2. Then in a state in which either or both of the signal S2 and the pulse P3 are being input, a pulse P4 (signal S6), with a pulse width corresponding to a period of the input, is output at a start timing of the input period, and when the pulse P4 is input, the imaging unit 7 is controlled to start imaging based on a start timing of the pulse P4. An X-ray imaging apparatus that can appropriately detect an imaging start timing and can perform taking of a good X-ray image while preventing malfunctions due to noise is thereby realized.Type: GrantFiled: March 7, 2006Date of Patent: August 11, 2009Assignee: Hamamatsu Photonics K.K.Inventors: Akira Taoka, Kazuhisa Miyaguchi
