3 Terms and definitions

GB/T 18988.3, GB/T 18989 and defined by the following terms and definitions apply to this document. 3.1 Attenuation correction attenuationcorrection; AC Correction of loss of radiant intensity after passing through the media.

4 test methods

4.1 Overview For single-photon emission tomography devices, the attenuation correction of any medium within the device's fault volume for attenuation correction should have the correct theory basis. The basis of the calibration is measuring the transmittance of the object through the object in the total field of view. The accuracy actually achieved is an important part of its quantitative ability Guarantee. 4.2 Purpose In the method, SPECT and CT scanning are performed on the motif of known components, and the linear attenuation coefficient obtained by using CT image conversion Value, the SPECT image attenuation correction to assess the accuracy of SPECT attenuation correction. Note. The results of this test are also affected by uniformity, scattering, etc. 4.3 method 4.3.1 Overview The transmission of X-ray radiation through the non-uniform attenuating medium is processed to give the attenuation correction model, which is used as the SPECT projection number It is part of the reconstruction process. The accuracy of attenuation correction is reflected in the reconciliation between the transmitted value and the true value. ......
