Abstract

The invention discloses a rapid construction method and system for human organ-intracavity three-dimensional geometry model, which is suitable for the rapid construction of complex cavities. The technical proposal is that: (1) one or more sensing elements are introduced into the intracavity; (2) in the intracavity the sensing elements are moved to collect the spatial location information of the intracavity to know the position or range of the intracavity; (3) according to the position or range of the intracavity, the intracavity surface three-dimensional geometry model is constructed. The rapid construction method and system for human organ-intracavity three-dimensional geometry model are applied in the field of organ model construction.

Description

technical field [0001] The present invention relates to a method and a system for rapidly constructing a three-dimensional geometric model of a human organ lumen, and in particular to a method and a system for rapidly constructing a three-dimensional geometric model of a human organ lumen by using a three-dimensional positioning sensor installed on a catheter head. Background technique [0002] Atrial fibrillation is an irregular heartbeat that originates in the atria, usually causing the heart to beat faster than 300 beats per minute. There are approximately 2.2 million patients with atrial fibrillation in the United States, and the number of new cases of atrial fibrillation reached 200,000 in 2006, while the number of patients with atrial fibrillation in China is more than 10 million. According to relevant data in China, the risk of stroke in patients with atrial fibrillation is 6 times that of normal people, and patients with atrial fibrillation often feel palpitations, c...
