Prostate cancer is one of the most common cancers among men and its early detection is critical for its successful treatment. The use of multimodal imaging, such as MR-PET, is most advantageous as it is able to provide detailed information about the prostate. However, as the human prostate is flexible and can move into different positions under external conditions, it is important to localise the focused region-of-interest using both MRI and PET under identical circumstances. In this work, we designed five commonly used linear and quadrature radiofrequency surface coils suitable for hybrid MR-PET use in endorectal applications. Due to the endorectal design and the shielded PET insert, the outer face of the coils investigated was curved and the region to be imaged was outside the volume of the coil. The tilting angles of the coils were varied with respect to the main magnetic field direction. This was done to approximate the various positions from which the prostate could be imag...

用于前列腺MR-PET混合成像的直肠内线圈的设计，评估和比较。

前列腺癌是男性中最常见的癌症之一，其早期发现对其成功治疗至关重要。使用多模态成像（例如MR-PET）最为有利，因为它能够提供有关前列腺的详细信息。然而，由于人类前列腺是灵活的并且可以在外部条件下移动到不同的位置，因此在相同的情况下使用MRI和PET定位聚焦的感兴趣区域非常重要。在这项工作中，我们设计了五个常用的线性和正交射频表面线圈，适用于直肠内应用中的混合MR-PET。由于直肠内设计和屏蔽的PET插入物，所研究的线圈的外表面是弯曲的，并且要成像的区域超出了线圈的体积。线圈的倾斜角相对于主磁场方向变化。这样做是为了近似前列腺可成像的各个位置。
