Embodiment Construction
[0025] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0026] Figure 1A Is a flowchart of an image attenuation correction method provided in an embodiment of the present invention, such as Figure 1A As shown, the image attenuation correction method includes the following steps.
[0027] Step 101: Collect a first image data set using a first imaging modality, reconstruct a first modality image according to the first image data set, and convert the first modality image into an attenuation correction image.
[0028] It should be noted that the first imaging modality is one of Computed Tomography (CT) or Magnetic Resonance Imaging (MRI).
[0029] Step 102: Use the second imaging modality to collect a second image data set carrying gated data, and reconstruct a second modality image of each gated phase acco...
