Abstract

The embodiment of the invention discloses a method, a device, a terminal and a storage medium for determining dynamic parameters of cerebral blood vessels. The method includes: simultaneously acquiring the left pulse wave of the left temporal artery and the right pulse wave of the right temporal artery of the subject; extracting the left characteristic parameters of the left pulse wave, and determining the left hemisphere according to the left characteristic parameters The left cerebrovascular dynamic parameters of the right brain; the right characteristic parameters of the right pulse wave are extracted, and the right cerebrovascular dynamic parameters of the right brain are determined according to the right characteristic parameters. The technical solution of the embodiment of the present invention can accurately, non-invasively and more specifically analyze the dynamic parameters of the left cerebral blood vessel and the right cerebral blood vessel dynamics, and is simple and practical.

Description

technical field [0001] Embodiments of the present invention relate to medical information processing technology, and in particular to a method, device, terminal and storage medium for determining cerebrovascular dynamic parameters. Background technique [0002] A large number of clinical experiments have shown that in the early stage of many cerebrovascular diseases, the parameters of cerebrovascular dynamics have changed significantly, and the changes of these dynamic parameters are often significantly earlier than the morphological changes. Therefore, accurate and non-invasive determination of cerebrovascular dynamic parameters is of great significance for early diagnosis of cerebrovascular diseases and physiological and pathological studies of cerebral circulation. [0003] Existing methods for determining cerebrovascular dynamic parameters may be transcranial Doppler technology, positron emission tomography technology, X-ray computed tomography technology, cerebrovascula...
