| 摘要 |
The invention relates to a method of imaging a target organ in a patient by SPECT, by using a gamma camera having a gamma detector, and by computer reconstructing the distribution of the radioactivity inside the patient's bo dy from planar images, acquired along at least one linear orbit performed in a transverse direction, wherein said gamma detector is perpendicularly provide d on its outer surface with a plurality of collimator septa in a mutually parallel arrangement and with at least one raised wall, extending in the longitudinal direction of the detector, transversely positioned to said sept a and with a substantial portion extending beyond said septa, said wall and sa id septa together forming a so-called rake collimator. The invention further relates to said rake collimator as such and to a combination of a gamma detector and a rake collimator. The invention also relates to an equipment f or performing the above method.
