Abstract

The invention discloses a CT (computed tomography) scanning method based on multiple voltage values and CT scanning equipment. On one hand, the CT scanning method based on the multiple voltage values is provided and comprises steps as follows: a voltage group is established and comprises at least one voltage value of an X-ray tube; a standard scanning entry is loaded and comprises a standard voltage value and a group of standard parameters; voltage values selected from the voltage group are received; a corresponding derivation scanning entry is established according to the standard voltage value, the standard parameters and the selected voltage values, and comprises the selected voltage values and one group of derivation parameters; CT scanning is performed according to the standard scanning entry and the derivation scanning entry.

Description

technical field [0001] The present invention relates to computed tomography. Background technique [0002] In the process of CT value research, it was found that the effect of different voltage values ​​of the tube on the CT value was statistically significant. Doctors can make a more accurate diagnosis of the subject according to the scanned images under different voltages. However, in the usual scan protocol design process, only a single voltage scan is designed. However, due to the very complicated correlation between the scan parameters, it is difficult for ordinary users to quickly and accurately design a scan with multiple voltage values. Therefore, how to allow users to generate multi-source agreements conveniently is a current problem. [0003] For dual-source CT, scanning with multiple voltage values ​​can be realized by using two bulb tubes with different voltage values. [0004] For single-source CT, the CT system only provides several default scan protocols f...
