An hour and a half.
Because of the different hospital configurations, CT three-dimensional reconstruction images are relatively more, usually more than 500 images, for the operation of the requirements will be higher, need to constantly try a variety of post-processing reconstruction methods, the best lesion exposure as well as the best diagnostic perspective, to find out what the ordinary CT missed the problem of the guidance of surgical methods and so on. Therefore, post-processing takes a long time, and it usually takes about half an hour to complete a case of 3D reconstruction, so under normal circumstances, it takes 2 hours for the CT 3D reconstruction to be able to produce the results.
If the lesion is more complex or difficult cases, need to discuss, it will take about 24 hours, but for emergency CT 3D reconstruction, the basic requirement should be about 30 minutes to produce results.
Currently, there are film self-printing system and network cloud film system, which can provide more convenience to patients, and the time to produce results is getting shorter and shorter. The time to take out the results of CT 3D reconstruction is a little longer than that of CT scanning, but taking into account the value of CT 3D reconstruction for diagnosis, as well as the superiority of the display of the lesion, it is worthwhile to take a little longer.
Expanded informationObjects three-dimensional reconstruction computer-aided geometric design (CAGD), computer graphics (CG), computer animation, computer vision, medical image processing, scientific computing and virtual reality, digital media creation and other areas of the **** of the scientific issues and core technologies. There are two main types of methods for generating a three-dimensional representation of an object within a computer.
One is to use geometric modeling software through human-computer interaction to generate a three-dimensional geometric model of the object under human control, and the other is to obtain the geometric shape of the real object through certain means.
The former realization technology has been very mature, there are a number of software support, such as: 3DMAX, Maya, AutoCAD, UG, etc., which generally use curved surfaces with mathematical expressions to represent the geometry. The latter is generally known as the three-dimensional reconstruction process, three-dimensional reconstruction refers to the use of two-dimensional projection to restore the object three-dimensional information (shape, etc.) of the mathematical process and computer technology, including data acquisition, pre-processing, point cloud splicing and characterization of the steps.
