1. A method of imaging a target organ in a patient by SPECT, by using a gamma camera having a detector/collimator combination including a gamma detector provided with a fan-beam collimator, comprising:

  • focusing the collimator to a focal line parallel to the patient'"'"'s body length;

    acquiring planar images by relative movement between the gamma camera and the patient'"'"'s body along at least on linear path in a direction perpendicular to the patient'"'"'s body length so that the collimator focal line traverses said target organ; and

    computer reconstructing the distribution of the radioactivity inside the patient'"'"'s body from the acquired planar images by using reconstruction algorithms.
