  • METHOD, APPARATUS, AND COMPUTER-READABLE STORAGE MEDIUM FOR GROWING SINGLE CRYSTAL BY USING CZOCHRALSKI TECHNIQUE
    Publication number: 20220389610
    Abstract: A method for growing a single crystal by using a Czochralski technique includes: in a cone process of a single-crystal growth by using the Czochralski technique, acquiring a first parameter corresponding to the single-crystal growth, and inputting the first parameter into a target model, because the target model is constructed by using a second parameter corresponding to the single-crystal growth in a historical cone process and a historical cone growing diameter in a historical cone growing operation, a cone growing diameter outputted by the target model according to the first parameter may be acquired, and then a cone growing operation is performed according to the first parameter and the cone growing diameter. At this point, the target model sufficiently learns from the experience of the historical cone process and the cone growing process.

  • Methods and systems for imaging performance analysis
    Patent number: 10607099
    Abstract: A method for analyzing performance of an imaging device including a scanner with a phantom includes receiving image data related to a scanning, by the scanner, of a first part of the phantom including at least part of a first test component. The method also includes obtaining at least one positioning parameter indicative of a positioning manner of the phantom during the scanning. The method further includes generating a first test image based on the received image data and determining a first region of interest (ROI) related to the first test component in the first test image based on the at least one positioning parameter.
