摘要:
The present disclosure relates to a method of assessing heart function and a system for assessing heart function. In detail, the present disclosure relates to a measuring a change in oxygenation or blood flow in the heart of the subject in response to a breathing maneuver and comparing the change in oxygenation or blood flow to a control. The change in oxygenation may be measured by segmenting an image of a heart, determining the signal intensity of a region of interest in a segment of the image and comparing the signal intensity to a control. An abnormal change in oxygenation blood flow or signal intensity in the heart compared to the control is indicative of reduced heart function. The disclosure further relates to a system for diagnosing heart disease which comprises an imaging device and processor configured to assess heart function.
摘要(中):
本公开涉及评估心脏功能的方法和用于评估心脏功能的系统。 详细地说,本公开内容涉及测量受试者的心脏中的氧合作用或血液流动的变化,以响应于呼吸机动并将氧合或血流量的变化与对照相比较。 可以通过分割心脏的图像来测量氧合的变化,确定图像的片段中的感兴趣区域的信号强度并将信号强度与对照相比较。 与对照相比,心脏中氧合血流量或信号强度的异常变化表明心脏功能降低。 本公开还涉及用于诊断心脏病的系统,其包括被配置为评估心脏功能的成像装置和处理器。
