    • A method is disclosed for determining positron emission measurement information in the context of positron emission tomography. The method includes carrying out a positron emission measurement, in a body area of a subject to be examined, to record positron emission measurement information with point resolution and determining a time frame of the measurement by, at the same time, generating images of the body area to be examined with a relatively higher time resolution and with point-resolved image data, using a second imaging method. Further, a local shift of points of individual images of the second imaging method is determined, caused by movement processes of the subject to be examined, and as a function thereof, of the positron emission measurement information for at least a part of the measurement period and of the body area to be examined. Finally, the positron emission measurement information is adjusted as a function of the determined shift.
    • 公开了一种用于在正电子发射断层摄影的背景下确定正电子发射测量信息的方法。 该方法包括在待检查对象的身体区域中进行正电子发射测量,以记录具有点分辨率的正电子发射测量信息,并且通过同时生成身体的图像来确定测量的时间范围 使用第二成像方法以相对较高的时间分辨率和点分辨图像数据进行检查的区域。 此外,由第二成像方法的各个图像的点的局部偏移由待检查对象的移动处理确定,并且作为其功能,确定至少部分测量周期的正电子发射测量信息 以及要检查的身体区域。 最后,调整正电子发射测量信息作为确定的位移的函数。
