  • Publication number: 20100208870
    Abstract: Scattered radiation is estimated by using a reduced image generated from a projection image, and the scattered radiation image of the projection image is acquired by enlargement processing. The scattered radiation correction of the projection image is executed by subtracting the obtained scattered radiation image from the projection image. In addition, when a primary X-ray image and a scattered radiation image in each projection direction are to be obtained by sequential approximation calculation, a primary X-ray image which has already been identified in an adjacent projection direction is used as a first estimated value (initially set value) in next sequential calculation.

  • Publication number: 20050148831
    Abstract: A patient terminal can communicate with doctor terminals and a center terminal via a communication network. The patient terminal acquires vital data from a measuring device with a receiving unit. A control unit determines whether the vital data contains an abnormal value and the necessity of messaging depending on the presence or absence of a manual messaging request with a message button and selects the doctor terminal or the center terminal. When it is determined that messaging is necessary, the control unit makes a communication unit call the selected terminal.

  • Patent number: 5485839
    Abstract: An ultrasonic wave medical treatment in which the position of the focal point of the ultrasonic waves, the temperature in a vicinity of the object to be treated, and the effect of the treatment can be determined easily and accurately. The three-dimensional image information of the object to be treated obtained by a computed tomography device is utilized in locating the focal point. In case of using a nuclear magnetic resonance imaging device as the computed tomography device, the T2 weighted image and the chemical shift data can be used in checking the effect of the treatment and the temperature in a vicinity of the object. The endocavitary probe equipped with temperature and intensity sensors may also be used. The ultrasound tomographic images obtained by the ultrasound tomographic imaging device may also be used in conjunction with the three-dimensional image information. Sequential shifting of the focal point of the ultrasonic waves may be employed to reduce adverse influence due to the cavitation.
