Autosegmentation of cardiac substructures in respiratory-gated, non-contrasted computed tomography images.

ABSTRACT:

Background

Radiation dose to specific cardiac substructures can have a significant on treatment related morbidity and mortality, yet definition of these structures is labor intensive and not standard. Autosegmentation software may potentially address these issues, however it is unclear whether this approach can be broadly applied across different treatment planning conditions. We investigated the feasibility of autosegmentation of the cardiac substructures in four-dimensional (4D) computed tomography (CT), respiratory-gated, non-contrasted imaging.

Aim

To determine whether autosegmentation can be successfully employed on 4DCT respiratory-gated, non-contrasted imaging.

Methods

We included patients who underwent stereotactic body radiation therapy for inoperable, early-
