具有对由MR线圈导致的辐射吸收进行校正的混合MR/PET
摘要：
一种成像方法包括：利用与受检者设置在一起的磁共振部件(30，30′)采集受检者的磁共振数据；利用与所述受检者设置在一起的所述磁共振部件采集所述受检者的核成像数据；相对于所述核成像数据的参照系确定所述磁共振部件的位置；以及重构所述核成像数据(60)以产生所述受检者的至少一部分的核图像(62)。所述重构包括根据所述磁共振部件的密度图(46)调节所述核成像数据和所述核图像的至少一个，以及相对于所述核成像数据的参照系确定所述磁共振部件的位置，以对所述核图像进行由所述磁共振部件导致的辐射吸收的校正。
摘要（英）：

An imaging method comprises: acquiring magnetic resonance data of a subject using a magnetic resonance component (30, 30') disposed with the subject; acquiring nuclear imaging data of the subject withthe magnetic resonance component disposed with the subject; determining a position of the magnetic resonance component respective to a frame of reference of the nuclear imaging data; and reconstructing the nuclear imaging data (60) to generate a nuclear image (62) of at least a portion of the subject. The reconstructing includes adjusting at least one of the nuclear imaging data and the nuclear image based on a density map (46) of the magnetic resonance component and the determined position of the magnetic resonance component respective to the frame of reference of the nuclear imaging data tocorrect the nuclear image for radiation absorption by the magnetic resonance component.
