Embodiment Construction

[0029] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0030] One of the imaging techniques of spectral CT can be dual-tube dual-energy imaging. This technology can include two sets of tubes and detectors embedded in the CT frame. The two tubes are arranged at a certain angle. The tubes generate X-rays at the same time, one tube produces high kVp X-rays, and the other tube produces low kVp X-rays. The two systems collect data information ...

Abstract

The invention provides an image processing method and device. The method comprises the steps that the image data of a hybrid energy image of power spectrum electronic computed tomography CT are acquired; tissue segmentation is performed on the hybrid energy image according to the image data so as to obtain different tissues; as for each type of tissue, the base material corresponding to the tissueis adopted for decomposition so that different energy levels of single energy tissue images corresponding to the tissue are obtained; and as for each energy level, different tissues of single energytissue images corresponding to the energy level are combined so as to obtain the single energy image corresponding to the energy level. The obtained single energy image is enabled to be clearer in theaspect of material distinguishing display so that the quality of the single energy image can be enhanced.

Description

technical field [0001] The present disclosure relates to medical imaging technology, in particular to an image processing method and device. Background technique [0002] In conventional CT (Computed Tomography, electronic computerized tomography), the X-rays produced by the tube have continuous energy distribution, and multi-energy spectrum CT (Multi-energy / spectral CT) imaging is to use the material to produce different absorption under different X-ray energies , to provide more image information than conventional CT. For example, spectral CT imaging can decompose the mixed energy of traditional X-rays into multiple single-energy images of different keV levels between 40-140keV, and these single-energy images can show the different tissues and organs and lesions at different X-ray energy levels. The CT value curve provides richer information for the origin of lesions and the identification of benign and malignant. [0003] In order to obtain the above-mentioned single-en...
