Abstract

Claims (11)

1. A method of using a radioactive emission camera in SPECT imaging, the method comprising:

administering a dose of radiopharmaceutical to a patient;

using a radiation emission camera, obtaining initial SPECT imaging data from a region of the body of said patient to be imaged, said obtaining being in an initial view or sequence of views; and

while continuing to acquire data, analyzing said initial SPECT imaging data to determine further views required to obtain a required image quality of SPECT imaging, wherein said analyzing said initial data to determine further views comprises defining a set of viewing parameter values and wherein said viewing parameter values comprise one member of the group consisting of: detector photon count; changes in detector photon count between views; geometric properties of a reconstructed body structure; and information theoretic measures defining a data quality.

2. The method of claim 1 , wherein said analyzing said initial data to determine further views comprises defining a set of viewing parameters.

3. The method of claim 2 , wherein said viewing parameter values further comprise detector saturation.

4. The method of claim 1 , wherein said viewing parameters comprise one member of the group consisting of: detector location; detector orientation; collection angle and measurement duration.

5. The method of claim 1 , wherein said analysis comprises defining a measurement error comparing a square root of an obtained photon count to said defined measurement error.

6. The method of claim 1 , wherein said analysis comprises identifying a pathological feature and said further views comprise a first zoom position towards said identified pathological feature.

7. The method of claim 6 , comprising carrying out a further analysis and finding a second zoom position towards said identified pathological feature.

8. The method of claim 1 , wherein the required image quality comprises a predetermined image quality.
