Description: ：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.

Description: 本文介绍了一种结合live wire算法和活动轮廓模型的医学图像序列的分割方法.我们通过把live wire
算法和图像分割中一般的区域增长方法结合来改进live wire算法,并用改进后的算法来对医学图像序列中的单张或
多张切片进行交互式的准确分割.然后计算机利用活动轮廓模型来自动分割相邻的未分割切片.我们通过在活动轮廓
模型的边缘点中引入记录已分割物体边缘附近局部区域特征的灰度模型来把已分割切片中的物体与背景的局部区域
特征带入相邻的未分割切片中,并用由灰度模型定义的区域相似性代替活动轮廓模型中的外能来引导边缘轮廓收敛
到物体的实际边缘.本文还介绍了一种基于live wire算法思想的简单的分割结果交互式修补方法.实验表明我们的算
法仅需少量用户交互就能快速准确的从医学图像序列中分割出感兴趣的物体

Description: Abstract—In this study, we propose a novel approach for accurate
3-D organ segmentation in the CT scan volumes. Instead of
using the organ’s prior information directly in the segmentation
process, here we utilize the knowledge of the organ to validate a
large number of potential segmentation outcomes that are generated
by a generic segmentation process. For this, an organ space
is generated based on the principal component analysis approach
using which the fidelity of each segment to the organ is measured.
We detail applications of the proposed method for the 3-D segmentation
of human kidney and liver in computed tomography scan
volumes. For evaluation, the public database of theMICCAI’s 2007
grand challenge workshop has been incorporated. Implementation
results show an average Dice similarity measure of 0.90 for the segmentation
of the kidney. For the liver segmentation, the proposed
algorithm achieves an average volume overlap error of 8.7 and
an average surface distance of 1.51 mm.-Abstract—In this study, we propose a novel approach for accurate
