Publication number: 20180199821Abstract: An acoustic wave detector detects photoacoustic waves generated by absorbing measurement light emitted toward a subject, and reflected acoustic waves with respect to acoustic waves transmitted toward the subject. A preamplifier amplifies a detection signal output by the acoustic wave detector. A bypass unit is intended to output the detection signal without passing through the preamplifier. Controller causes the preamplifier to enter an operating state and selects a first path along which the detection signal is amplified by the preamplifier and then is input to the reception circuit as a signal path in a case where the photoacoustic waves are detected. The controller stops an amplification operation in the preamplifier and selects a second path along which the detection signal is input to the reception circuit via a bypass uni as the signal path in a case where reflected acoustic waves are detected.Type: ApplicationFiled: March 14, 2018Publication date: July 19, 2018Applicant: FUJIFILM CorporationInventors: Atsushi HASHIMOTO, Atsushi OSAWA, Kaku IRISAWA, Keiji TSUBOTA

Patent number: 9538978Abstract: An X-ray imaging system includes an X-ray imaging apparatus and an access controller, which controls communication access of the X-ray imaging apparatus having an electronic cassette for forming an X-ray image and wirelessly transmitting the X-ray image. Before the electronic cassette starts transmitting the X-ray image, a priority request signal for priority of the first radio communication channel to the electronic cassette over a portable terminal device of radio communication is received. Upon receiving the priority request signal, presence of the portable terminal device is checked, in which a radio communication channel of overlap of frequency on the first radio communication channel is used. In presence of the portable terminal device with the overlap, the portable terminal device is regulated in communication regulation while the electronic cassette transmits the X-ray image. Also, the X-ray imaging apparatus is communicable by use of a communication network in wireless communication connection.Type: GrantFiled: September 16, 2014Date of Patent: January 10, 2017Assignee: FUJIFILM CorporationInventors: Kazuhiro Makino, Keiji Tsubota, Yoshimitsu Kudo, Yasunori Ohta
