Quantitative analysis of gated myocardial perfusion SPECT

Abstract

The paper considers the problem of gated myocardial perfusion single photon emission computed tomography (SPECT) data processing. An approach to the quantitative analysis of gated myocardial perfusion SPECT data used in software developed in the SPbSU is presented. The article presents and formalizes the complete data processing workflow. All the main tasks of the data processing are considered. Mathematical representation of problem domain objects is presented. A detailed algorithm of the data processing is given. The algorithmis implemented as component of the data processing software suite.

Challenges of gated myocardial perfusion SPECT processing

“…Mathematical processing workflow shown on the fig. 1 is thoroughly explained in [Ploskikh and Kotina, 2018]. At the initial stage the phase and magnitude threedimensional images are calculated from the source data.…”

“…A number of different definitions of latitude are used in geodesy, but little attention is paid to their application in the context of the LV coordinate system. The parametric latitude β was used in previous work [Ploskikh and Kotina, 2018]. This paper considers the application of the rectifying latitude.…”

“…Quantitative analysis of gated myocardial perfusion SPECT was considered in [Ploskikh and Kotina, 2018]. This paper continues research in this direction, and some challenges of ECG-gated SPECT data processing are discussed, such as the ellipsoid coordinate system calculation, polar map representation, regional parameters estimation and circular statistics application.…”
