Embodiment 1

[0015] figure 1 It is a flow chart of the three-dimensional effect display method for images provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of three-dimensional effect display of tubular structures such as blood vessels / neural tubes in images captured by X-ray equipment. The method It can be performed by a three-dimensional effect display system installed in a computer device. The computer equipment includes, but is not limited to: medical image display equipment, a server connected to a computer used by a doctor, and the like. The display system displays the tubular structure with a three-dimensional effect for the doctor by performing the following steps.

[0016] Step S110, discretely sampling a plurality of fitting central points for the central axis of the tubular structure in the image.

[0017] Here, the display system can extract the corresponding tubular structure from the acquired image according to the feature informat...

Embodiment 2

[0046] figure 2 It is a flow chart of step S110 in the method for displaying images with a three-dimensional effect provided in Embodiment 2 of the present invention. According to actual application needs, doctors may only need to view the projection image of a section of dental nerve canal / vessel. Therefore, different from the above-mentioned embodiments, the display system does not determine discrete sampling points of all tubular structures in the image. Therefore, step S110 in each of the above embodiments includes: steps S111 and S112.

[0047] Step S111 , based on at least two selected points acquired along the tubular structure in the image, intercept and fit the tubular structure distributed by each selected point.

[0048] Specifically, when the display system displays the image to the doctor, it also receives at least two selection operations performed by the doctor on the tubular structure. The display system saves the selected points corresponding to the sequen...

Embodiment 3

[0054] image 3 Shown is a schematic structural diagram of a three-dimensional effect display system for images provided by Embodiment 3 of the present invention. This embodiment is applicable to the situation where three-dimensional effect display is performed on tubular structures such as blood vessels / neural tubes in images captured by X-ray equipment. The display system is installed in computer equipment. The computer equipment includes, but is not limited to: medical image display equipment, a server connected to a computer used by a doctor, and the like. The display system 1 includes: a fitting selection module 11 , a three-dimensional sampling module 12 , a projection module 13 , a projection translation module 14 , and a rendering module 15 .

[0055] The fitting selection module 11 is used to discretely sample a plurality of fitting central points of the central axis of the tubular structure in the image.

[0056] Here, the fitting selection module 11 can extract th...

Abstract

The invention discloses an image 3D display method and system. The method comprises: the system utilizing a B-spline curve in an image to fit a tubular structure, and discretely sampling a plurality of fitting central points on the central axis of the tubular structure; constructing a spherical coordinate system having the fitting central points as the origin of coordinates, and the axial radius of the tubular picture as the spherical radius, and collecting spherical discrete sampling points in the spherical coordinate system; separately performing projection coordinate conversion on each discrete sampling point and each fitting central point based on the 3D rotation angle of the obtained tubular structure; moving each projected discrete sampling point with the offset among projected fitting central points to obtain the projection of the tubular structure; and performing 3D rendering on the projection of the tubular structure, and displaying results for users. The method and system solve the problem that in adjusting an image angle in real time, a doctor can not timely display image effects.

Description

technical field [0001] Embodiments of the present invention relate to data processing technologies, and in particular, to a method and system for displaying images with three-dimensional effects. Background technique [0002] In minimally invasive surgery, doctors need to take X-ray / contrast images around the lesion many times in order to grasp the location and distribution of blood vessels and neural tubes in real time. For example, during tooth extraction, doctors need to perform real-time positioning and 3D display of the canal of the dental canal, so as to ensure that damage to the canal of the dental canal is avoided during the dental operation. [0003] At present, the commonly used scheme to display the dental nerve canal in 3D effect is: extract the two-dimensional figure of the dental nerve canal in the image taken by X-ray, and construct the two-dimensional figure according to the 3D modeling technology, which will have a 3D effect Graphics of the dental canal are...
