Psychosurgery

Psychosurgery

Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

集成基于图谱的细分与路径查找算法 (Dijkstra,A*).
纳入由外科医生评估的敏感大脑区域的风险评分 (0-10级).
使用的管道图像处理技术:分数异构 (FA),相对异构 (RA),球形测量 (SM) 和线性测量 (LM).

主要成果:

首个框架将白质道和基于图谱的细分结合起来,用于外科路径规划.
动态框架结构允许添加各种路径查找算法和路径宽度.
在NRRD格式中生成手术路径,以便与第三方软件兼容.
外科医生的验证证实了该框架能够识别标准手术途径 (例如,前部跨,跨).

结论:

拟议的框架成功地产生了由外科医生评估的多种潜在的手术途径.
该框架确定了现实世界的外科手术途径,验证了其临床相关性.
未来的改进包括对复杂的手术条件的操作时间和并发症率等参数的整合.
