摘要： PROBLEM TO BE SOLVED: To secure an entire region in the visual field of a detector to the size of the section of a specimen and at the same time fully bring the detector closer to the specimen in a gamma camera.
SOLUTION: A plurality of detectors 10a, 10b, and 10c are arranged at the outer part with the section of a specimen as a center so that radiation incidence surfaces 11a, 11b, and 11c surround the section of the specimen, are moved in the radius direction of the section of the above specimen and at the same time are moved in a direction that orthogonally crosses the radius direction, and the position of the detectors 10a-10c is set to the size of the section of the above specimen. As a result, the entire region is secured in the visual field of the detector to the size of the different section of the specimen and at the same time the detector can be fully brought into contact with the specimen, thus improving the picture quality of an obtained radiation image.

摘要： PROBLEM TO BE SOLVED: To improve the picture quality of a radiation image being obtained by avoiding the incidence of radiation from the background part of the target organ of a specimen and reducing the intake of noise in a gamma camera.
SOLUTION: A gamma camera is provided with a detector for applying radiation being discharged from a target organ due to given radioparmaceuticals for detection and generates a radiation image from the position information on the above incidence radiation by processing the detection signal. In the gamma camera, a plurality of detectors 10a and 10b that are thin are directed in the same direction and adjacent side end parts are connected, and at the same time an angle θ between radiation incidence surfaces can be set to an arbitrary angle to avoid the incidence of radiation from the background part of the target organ of a specimen, thus reducing the intake of noise while avoiding the incidence of radiation from the background part of the target organ and improving the picture quality of the obtained radiation image.

摘要： PURPOSE:To diagnose a body to be inspected on a low-floor type bed for movement in a hospital by enabling a 2nd detector to move at right angles to the moving direction of a 1st detector. CONSTITUTION:The 1st detector 3 is fitted movably in the length direction of a support column 1 and the 2nd detector 7 is fitted rotatably through a rotary mechanism 11 at a position on the support column 1 opposite the 1st detector 3. Then when a diagnosis is taken, the detector 7 is so shifted as to face the detector 3 and then the low-floor type bed for in-hospital movement can be moved to between the detector 3 and the floor surface right below it, so that the body to be examined need not be moved to a bed for exclusive use and has no pain.

摘要： PURPOSE:To facilitate a weight balance adjustment by housing particulate materials in a container to compose a counter weight with the prevention of the movement of the particulate material. CONSTITUTION:A particulate material 11 flows into a cylindrical container 10 from an intake port 10c, the inflow thereof is stopped when a specified weight is estimated to be reached and a lid is put on the intake port 10c to finish the housing. Then, a pair of keep plates 14 and a plurality of cap screws 15 makes up a movement prevention means and the keep plate 14 presses the particulate materials 11 by screwing the cap screw 15 to complete a counter weight W. Then, when an estimated weight differs from a given weight, the particulate materials 11 are increased or decreased bit by bit at the intake port 10c or at an takeoff port 10d thereby enabling the adjusting of the weight.

摘要： PURPOSE:To improve the sensitivity of a scintillation camera by a relatively easy method by using a collimator which has plural linear focuses in the direction of the axis of rotation of the detector of the scintillation camera to a subject. CONSTITUTION:The collimator 7 has a convergence point 12 only in an X-axial direction and no convergence point in a Y-axial direction and is a parallel collimator. Then convergent lines 13 forming the convergence point 12 form plural plural visual fields of the scintillation camera in a wedgelike shape 15 for the subject. While the scintillation camera detector which includes this collimator 7 is rotated about the axis of rotation, information on gamma rays emitted by the subject 14 at each angle is collected to improve the sensitivity by the relatively easy method.

摘要： PURPOSE:To minimize an insensitive region and to obtain a good quality image, by providing a square photoelectric surface to each of photomultiplier tubes and arranging said tubes in a square pattern. CONSTITUTION:The light incident surface of each of photomultiplier tubes 3 has a square photoelectric surface 21 and a square cross-section at a part thereof and said tubes are arranged in a square pattern. By this square arrangement, the insensitive region 8 of a detector formed between the container 6 of the detector and an effective visual field 7 can be minimized and, therefore, a good quality image is obtained.
