Embodiment Construction
[0021] Various details involved in the technical solution of the present invention will be described in detail below in conjunction with the drawings and embodiments. It should be pointed out that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.
[0022] Different from the traditional method of loading three-dimensional intravascular ultrasound (IVUS) images for each frame and processing them separately, the present invention adopts a method based on three-dimensional image interpolation, so all N frames of images are regarded as a three-dimensional volume data, and the IVUS long axis Image construction can be regarded as a sampling process of three-dimensional plane to three-dimensional volume data, which requires a suitable coordinate system to ensure correct calculation.
