METHOD AND APPARATUS FOR MODULATING CURRENT IN COMPUTED TOMOGRAPHY IMAGING SYSTEM |
| 摘要 |
A method and apparatus of current modulation in a computed tomography imaging system are provided. The method may include: selecting a plurality of sample points from an expected current modulation curve as approach points; establishing an actual current modulation curve, wherein an actual current value of the actual current modulation curve at an approach point approximates an expected current value of an expected current modulation curve, and a variation rate of the actual current is within an allowed range of the computed tomography imaging system; and modulating a current in an X-ray tube of the computed tomography imaging system according to the actual current modulation curve. According to the disclosure, an image valuable to the diagnosis can be obtained with the smallest radiation dose. |
