Abstract

The invention belongs to technical fields of medical measurement, computer simulation and computational fluid mechanics and discloses a heart left ventricle flow field domain numerical simulation method, a computer and a computer program. Contour extraction is performed according to an echocardiogram-based left ventricle contour extraction method to realize left ventricle blood flow field dynamicsimulation; a left ventricle initial contour is extracted on the basis of echocardiogram, contour pixel point coordinates are acquired according to a quick connected domain method, and a left ventricle grid model is automatically generated on the basis of an extracted heart left ventricle contour model; optimal boundary conditions are set, and a heart left ventricle flow field change process is dynamically simulated. Cardiovascular disease occurrence and development pathophysiology and pathological anatomy foundation can be better revealed, and valuable reference information can be provided for prevention and treatment of the cardiovascular disease.

Description

technical field [0001] The invention belongs to the technical fields of medical measurement, computer simulation, and computational fluid dynamics, and in particular relates to a numerical simulation method, a computer, and a computer program for the left ventricular flow field of the heart. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Blood perfusion of various tissues and organs throughout the human body system. The anatomical function of the heart is extremely complex. It transmits human blood in the form of a "pump". Its internal blood fluid movement state is the external manifestation of the heart's function as a "pump", and it is also an important basis for judging the health of the heart function. The blood flow field in the ventricle is more complex and changeable. The blood flow field in different phases of the cardiac cycle is mainly manifested as dynamic and continuously changing lamin...
