Abstract

Radioimaging methods, devices and radiopharmaceuticals therefor.

Claims

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

obtaining initial data from a region of the body to be imaged in an initial view or sequence of views; and

while continuing to acquire data, analyzing said initial data to determine further views required to obtain a required image quality.

2. The method of claim 1, wherein said obtaining defining further views comprises defining a set of viewing parameters and viewing parameter values.

3. The method of claim 2, wherein said viewing parameter values comprise one member of the group consisting of:

detector photon count;

changes in detector photon count between views;

detector saturation;

geometric properties of a reconstructed body structure; and

information theoretic measures defining a data quality.

4. The method of claim 2, 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 and 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.
