Multi-mode X-ray imaging equipment for detecting foreign matters in soft tissues and method thereof

Abstract

The invention relates to the biomedical field and medical equipment technology, and discloses multi-mode X-ray imaging equipment and method for detecting foreign matters in soft tissues. The imaging detection method comprises the following steps: a working state adjustment step, a sample collection step, a signal analysis step, an image enhancement step and the like. The imaging equipment comprises a working state adjusting system, a data acquisition system, a computer data processing system and the like. According to the method, information of lesion in three aspects including the absorption capacity of a sample, electron density distribution and small-angle scattering capacity can be obtained, and by integrating and calculating the information of the absorption capacity and the small-angle scattering capacity of the sample, an R value image with certain single-angle substance identification capacity can be obtained; and therefore, the detection of common foreign matters is more comprehensive. In different subcutaneous levels, different comparison results have different advantages on identification of different types of foreign matters.

Description

technical field [0001] The invention relates to the field of biomedicine and medical equipment technology, in particular to a multi-mode X-ray imaging device and a method thereof for detecting foreign bodies in soft tissues. Background technique [0002] X-ray transmission imaging and its related X-ray computed tomography (CT) technology, as a basic method for obtaining medical images, has low cost, With the characteristics of fast speed and high efficiency, it is widely used in biomedical research and disease diagnosis and treatment. [0003] At present, the X-ray imaging devices commonly used in hospitals are based on the principle of point projection imaging, using the difference in X-ray absorption ability caused by the element composition and density changes inside the detected object to obtain images with a certain contrast (or contrast). Although the absorption contrast images given by the existing X-ray imaging devices contain rich information about the internal str...

Problems solved by technology

For example, breast cancer, breast fibroadenoma, mammary gland hyperplasia, articular cartilage degeneration, and arthritis are all very difficult to diagnose and differentiate

[0005] Secondly, the existing X-ray imaging device is limited by the millimeter focal spot ray source and the electronic recording device (such as flat panel detector, scintillator array, etc.) (0.2-0.5mm), which cannot clearly reflect the appearance of some small-scale but highly indicative lesion features (such as calcifications in the breast) or the morphology of tissues and organs with porous structures (such as lungs, bones), which is not conducive to Early detection, diagnosis and treatment of related diseases (such as breast cancer, emphysema, etc.)
