最近的技术蓬勃发展，以下通过在强磁场，从而影响PET图像分辨率和衰减校正领域的改变正电子的运动技术障碍。

The technology recently blossomed following passing a technical hurdle of altered positron movement in strong magnetic field thus affecting the resolution of PET images and attenuation correction.

靶组织体积的计算受PET图像采集模式，散射校正方法，衰减校正方法，重建技术，图像显示模式，正电子药物等因素影响。

Many factors work on the target volume calculation, such as PET image acquisition mode, scatter correction, attenuation correction, reconstruction method, image display mode, positron pharmacy.
