摘要： Provided is a calibration assembly, including: a base; and a plurality of calibration wires dispersedly connected to the base, wherein an absorption capacity of the calibration wire for X-rays is greater than an absorption capacity of the base for X-rays Through a specific structure design of a plurality of calibration wires in the calibration assembly in the present disclosure, the calibration wires are dispersedly connected to the base, and taking advantage of the characteristics that the absorption capacity of the calibration wire for X-rays is greater than the absorption capacity of the base for X-rays, the above-mentioned calibration wires are applied to the calibration phantom, and the calibration phantom is scanned in the scanning system. By continuously adjusting the geometric parameter values in the imaging method, the optimal geometric parameter values that are closest to the real scanning system structure may be obtained, thereby improving the imaging effect of the scanning system.

摘要： This application discloses an image display method, apparatus and device and a computer storage medium. The image display method includes: determining object positions of a target object in multiple first images; processing the multiple first images based on the object positions and a target position and generating multiple second images in one-to-one correspondence with the multiple first images, wherein the target object is positioned at the target position in the second images respectively, and the target position is a same position in the multiple second images; and displaying the multiple second images. According to embodiments of the application, when the images are displayed, the target object can be always displayed at the target position, thereby facilitating the user to view the target object.
