:探索一种能有效抑制和消除颅脑MRI运动伪影产生的方法,以提高图像质量和工作效率。方法:利用包装CT管球的海绵,设计并制作了2 cm x 7.5 cm x 22 cm,3 cm x 7.5 cm x 22 cm,4 cm×7.5 cm x 22 em等3种规格的海绵垫,
配合使用颅脑正交线圈进行颅脑MRI检查。结果:采用“加垫法”行颅脑MRI检查2 638例。其中,一次性扫描成功2 633
例(占99.81%),失败5例(占0.19%);
在扫描失败的5例患者中,第2次扫描时配合使用医用绷带成功4例。失败l例。结论:采用“加垫法”行常规颅脑MRI扫描,方法简单、可靠。可有效抑制和消除运动伪影的产生,提高图像质量和工作效率。(To explore a brain can effectively inhibit and eliminate motion artifacts of MRI approach to improve the image quality and efficiency. Methods: The CT tube packing sponge ball, designed and made 2 cm x 7.5 cm x 22 cm, 3 cm x 7.5 cm x 22 cm, 4 cm × 7.5 cm x 22 em 3 sizes, etc. sponge pad, with the quadrature head coil using brain MRI. Results: The " plus cushion Law" the Brain MRI examination 2 638 cases. Among them, the one-time scan is successful 2 633 cases (99.81 ), failed in 5 cases (0.19 ) Conclusion: " plus cushion Law" routine brain MRI scan, the method is simple and reliable. Can effectively suppress and eliminate motion artifacts, and to improve image quality and efficiency.)

lmse
The LMSE package contains two subroutines. LMSE computes the minimum mean square error (MSE) possible if one image is allowed to be linearly scaled in intensity. LMSEDIFF computes the difference image after the target image is scaled according to the scaling that minimizes the MSE. This is a better way to compare images if the absolute magnitude of the intensity has no meaning.
