Embodiment 1

[0030] The solutions provided in the embodiments of the present application can be applied to any system with CT scanning capability, such as a CT scanning system and the like. figure 1 A schematic diagram of an application scenario of the CT scanning solution provided in the embodiment of the present application, figure 1 The illustrated scenario is only one example of scenarios to which the technical solutions of the present application can be applied.

[0031] In the medical field, CT has been widely used as a basic inspection method, but at present, CT is limited by its spatial resolution, and cannot meet the requirements of diagnosis in the imaging of fine human structures such as temporal bones. It will make doctors unable to use CT as an inspection method when diagnosing small hidden lesions, thus affecting the efficacy of CT in clinical application.

[0032] After the CT scan data is obtained, CT data reconstruction needs to be performed to obtain CT scan images that ...

Embodiment 2

[0059] figure 2 A flow chart of an embodiment of the CT data reconstruction method provided in the present application. like figure 2 As shown, the CT data reconstruction method may include the following steps:

[0060] S201, acquiring detailed-view scan projection data and wide-view scan projection data.

[0061] In step S201, the detail scan projection data and the wide view scan projection data may be acquired respectively. For example, in this embodiment of the present application, a high-resolution detector may be used to perform a focused scan of the target region ROI. In this embodiment of the present application, a conventional resolution detector can also be used as a wide-view detector to perform a wider range of scanning. Therefore, in for example figure 1 In the scenario shown in , the scanning beams formed by conventional detectors and light sources and the scanning beams formed by high-resolution detectors and light sources form wide-view scans and detaile...

Embodiment 3

[0085] image 3 A schematic structural diagram of an embodiment of the CT data reconstruction apparatus provided in this application can be used to perform figure 2 method steps shown. like image 3 As shown, the CT data reconstruction apparatus may include: an acquisition module 31 , an estimation calculation module 32 , a first reconstruction module 33 , a second reconstruction module 34 and a determination module 35 .

[0086] The acquisition module 31 may be used to acquire detailed scan projection data and wide scan projection data.

[0087] The acquisition module 31 can acquire the detailed scan projection data and the wide scan projection data, respectively. For example, in this embodiment of the present application, a high-resolution detector may be used to perform a focused scan of the target region ROI. In this embodiment of the present application, a conventional resolution detector can also be used as a wide-view detector to perform a wider range of scanning. ...

Abstract

The invention discloses a CT data reconstruction method and device, electronic equipment and a computer readable storage medium. The method comprises the following steps: acquiring detailed view scanning projection data and wide view scanning projection data; performing target area projection estimation calculation on the detailed view scanning projection data to obtain detailed view estimation data; performing analysis and reconstruction processing on the detailed view estimation data to obtain first estimation image data of the target area; performing reconstruction processing on the wide-view scanning projection data to obtain second estimation image data; and determining high-resolution image data of the target area by using an image optimization model according to the first estimation image data and the first wide-view estimation image data. According to the embodiment of the invention, the data completeness characteristic of wide-view scanning and the high-resolution characteristic of detailed-view scanning can be combined to reconstruct the CT image, so that the quality of the reconstructed CT image is improved, and the reconstruction efficiency is greatly improved.

Description

technical field [0001] The present application relates to the technical field of medical equipment, and in particular, to a CT data reconstruction method and apparatus, an electronic device, and a computer-readable storage medium. Background technique [0002] In the medical field, CT has been widely used as a basic inspection method, but at present, CT is limited by its spatial resolution, and cannot meet the requirements of diagnosis in the imaging of fine human structures such as temporal bones. It will make doctors unable to use CT as an inspection method when diagnosing small hidden lesions, thus affecting the efficacy of CT in clinical application. [0003] After the CT scan data is obtained, CT data reconstruction needs to be performed to obtain CT scan images that doctors or patients can view intuitively. The difference often produces artifacts or distortions, which seriously affect the use of CT scan data. SUMMARY OF THE INVENTION [0004] Embodiments of the pre...
