20090092229 | RADIOLOGICAL IMAGING APPARATUS - A radiological imaging apparatus of the present invention comprises an image pickup device and a medical examinee holding device that is provided with a bed. The image pickup device includes a large number of radiation detectors and radiation detector support plates. A large number of radiation detectors are mounted around the circumference of a through-hole and arranged in the axial direction of the through-hole. The radiation detectors are arranged in three layers formed radially with respect to the center of the through-hole and mounted on the lateral surfaces of the radiation detector support plates. Since the radiation detectors are not only arranged in the axial direction and circumferential direction of the through-hole but also arrayed in the radial direction, it is possible to obtain accurate information about a γ-ray arrival position in the radial direction of the through-hole (the positional information about a radiation detector from which a γ-ray image pickup signal is output). The use of accurate information about γ-ray arrival increases the tomogram accuracy. As a result, the present invention enhances the tomogram accuracy, that is, the PET examination accuracy. | 04-09-2009 |

20130103417 | Medical Care Support System and Method Of Supporting Medical Care - Provided is a medical care support system for the sharing and reusing of medical information on the basis of a workflow which is a flow of medical-related services. A workflow step that was executed prior to an ongoing workflow step is selected by using a medical information database which has registered a workflow and information of each workflow step in association with medical information; and information is inputted by medical staff in the ongoing workflow step while the medical information registered in the selected workflow step being referred to; and the medical information being referred to and the inputted information are registered in the medical information database in association with the ongoing workflow step. | 04-25-2013 |
20140330066 | SYSTEM FOR IRRADIATING CHARGED PARTICLES AND METHOD FOR IRRADIATING CHARGED PARTICLES - A charged particle irradiation system is capable of shortening the irradiation time and the treatment time by performing efficient irradiation even when irregular variation occurs in the irradiation object during the gating irradiation. The extraction of the beam is stopped upon reception of a regular extraction permission end signal which is outputted based on a regular movement signal. An extractable state maintaining function operates upon the reception of the extraction permission end signal. When a preset standby time elapses without receiving an extraction permission start signal again during the standby time, the extractable state maintaining function finishes its operation and a charged particle beam generator decelerates the beam. Also, the extraction of the beam is stopped due to reception of an irregular extraction permission end signal during the irradiation. When the extraction permission start signal is received again during the standby time, the extraction of the beam is restarted. | 11-06-2014 |
20150036793 | RADIOTHERAPY SYSTEM - A radiotherapy system acquires an image which is necessary for positioning of a patient for radiation treatment and enables grasping of a positional relationship of a target in a treatment radiation irradiated state, a radiation passing area and a critical organ. An X-ray imaging device is attached to the rotatable support device and configured to apply X-rays to the subject from plural directions while rotating around the subject to perform X-ray imaging. A target recognizing device recognizes a three-dimensional position of the target in the subject from X-ray images acquired by the X-ray imaging device; and CT image generating devices are configured to select, from the X-ray images acquired by the X-ray imaging device, the images in which the position of the target recognized by the recognizing device satisfies the treatment radiation irradiation condition for the motion tracking treatment to perform image reconstruction and generate a cone beam CT image. | 02-05-2015 |
