Duchenne muscular dystrophy (DMD) is an X-linked recessive neuromuscular disorder, and the carriers of DMD can suffer from cardiac damage without muscle weakness, which can predispose to death. Consequently detecting and preventing cardiac damage in the early stage can improve the carriers' quality of life. The detection of early cardiac abnormalities and the evaluation of cardiac function for carriers mainly rely on the different examination methods, including electrocardiogram, echocardiogram, cardiovascular magnetic resonance, radioactive nuclide myocardial perfusion imaging and coronary angiography. Carriers of DMD with cardiac damage are assessed by different examination methods in different ways.

KylinRay-IMRT is the advanced radiotherapy treatment planning module of accurate radiotherapy system (KylinRay) aiming to provide accurate and efficient plan design platform. In this paper the system design, main functions and key technologies of KylinRay-IMRT were introduced. KylinRay-IMRT supports three dimensional conformal radiotherapy (3D-CRT), intensity modulated radiotherapy (IMRT) and many other types of treatment plan design with function modules including patient data management, image registration and fusion, image contouring, image three dimensional reconstruction and visualization, three dimensional conformal radiotherapy planning, intensity modulated radiotherapy planning, plan evaluation and comparison, and report print. KylinRay-IMRT has been tested by the national standard YY/T 0889-2013, the results showed that the performance of KylinRay-IMRT can fully meet the standard requirements.
