Method and system for conducting image measurement to obtain tumor standardized uptake value through nuclear medicine single photons

Abstract

The invention relates to a method and system for conducting image measurement to obtain the tumor standardized uptake value through nuclear medicine single photons. Image measurement is conducted to obtain the tumor standardized uptake value through single-photon emission computed tomography (SPECT) or obtain the tumor standardized uptake value through single-photon emission computer tomography / computer tomography (SPECT / CT). The method includes the photography step, the scattering correction step, the attenuation correction step, the image resolution ratio recovery step, the noise removal step and the uptake value calculation step. The method solves the problems of physical interference on dynamic single-photon emission computer tomography and patient movement, and therefore the capacity for quantifying the tumor standardized uptake value of patients can be achieved.

Description

technical field [0001] The present invention relates to an image measurement method and system design, in particular to a method and system for nuclear medicine single-photon image measurement of tumor standard uptake values. Background technique [0002] At present, in clinical practice, in order to measure the standardized uptake value (SUV) of tumors for drugs, it is first necessary to establish the ) obtained images with the same attributes. However, although PET or PET / CT can accurately measure the standard uptake value of tumors, they cannot be widely used in hospitals at all levels due to problems such as the popularity of contrast drugs and the high burden of examination funds. [0003] Compared with PET and PET / CT, the imaging modes of SPECT and SPECT / CT have the advantages of economical parity, and can be widely used in hospitals at all levels. However, traditional SPECT and SPECT / CT angiography have problems such as physical interference and low spatial resolutio...

However, although PET or PET / CT can accurately measure the standard uptake value of tumors, due to the popularity of contrast drugs and the high burden of examination funds, PET and PET / CT cannot be widely used in hospitals at all levels

[0003] Compared with PET and PET / CT, the imaging modes of SPECT and SPECT / CT have the advantages of economical parity, and can be widely used in hospitals at all levels. However, traditional SPECT and SPECT / CT angiography have problems such as physical interference and low spatial resolution. , diagnosis often encounters image artifacts and insufficient accuracy, and cannot be used to quantify tumor standard uptake values, thus limiting SPECT and SPECT / CT as an economical clinical tool for diagnosing tumor diseases
