    摘要: After the position of a collimator with respect to a gamma camera depending on the position of a detection plane in an examinee, gamma rays radiated from the examinee are detected by a scintillation detector via a collimator and a scintillator, and a signal from the scintillation detector is processed by a signal processing circuit and then transferred to an image reconstructing unit, which reconstructs a three-dimensional image of the radiation source in the examinee and displays the three-dimensional image on a display unit.

    摘要: An MRI system includes an MR signal acquisition section, an imaging processing section, a control signal generating section, and a control section. The MR signal acquisition section excites an MR phenomenon in a portion including a selected slice of an object to be examined, and detects MR signals generated by the MR phenomenon. The imaging processing section processes the MR signals to form an image based on MR data in the selected slice of the object. The control signal generating section generates a control signal for acquiring the MR signals in response to movement of the object. The control section controls the MR excitation operation and the MR signal acquisition operation of the MR signal acquisition section in accordance with the control signal.
