specific Embodiment 1

[0057] In some CT systems, due to the jump of focus in the Z direction of some tubes, it is usually necessary to use additional algorithms for correction. However, due to different tubes and different configurations, or different current scanning states, this algorithm does not need to be executed every time. The data reconstruction method of the present invention can dynamically judge whether to use the algorithm for correction during the reconstruction process according to the hardware information fed back by the system.

specific Embodiment 2

[0059] Users may reconstruct the same set of data of the same patient with different reconstruction parameters to obtain different reconstruction sequences. For different hardware configurations, these different reconstruction methods are also different. In order to ensure that users get better image quality, the data reconstruction method of the present invention can be based on actual physical information on the hardware (such as the size of the detector, X and Y The number of detectors in different directions, ASG height, aperture size, tube control information, etc.), dynamically select different reconstruction methods to obtain more efficient and accurate reconstruction results.

Abstract

The invention discloses a method for reconstructing medical image data. The medical image data includes scanning data obtained by scanning a measured object through system equipment. The method may include: acquiring scanning data; acquiring system equipment data; acquiring user's reconstruction requirements; judging whether the system equipment can meet the user's reconstruction requirements according to the system equipment data; dynamically selecting a reconstruction algorithm or / and correction method according to the judgment result and the system equipment data; and The selected reconstruction algorithm or / and correction method is used to reconstruct or / and correct the scan data. This method can extract useful information according to the impact of the hardware update on the system, and dynamically select different algorithms and signal processing procedures according to the information to meet the user's reconstruction needs.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method for reconstructing medical image data. Background technique [0002] In many fields, especially manufacturing, medical treatment, education and other fields, the application of equipment is gradually becoming popular. During the use of the device, it is inevitable to involve the problem of updating the hardware of the device. Due to the continuous development of hardware and machinery, even the same imaging device (for example, Computed Tomography (CT)) may have multiple different hardware configurations, and the different physical properties of these different hardware configurations will bring different signal responses to the imaging device and processing methods, thus bringing inconvenience to data reconstruction. [0003] The existing technical solution is to distinguish different types of hardware, the software is usually matched with the hardware, and any hardw...
