Parallel Transmission Technologies for Imaging the Brain and Body with 7 Tesla MRI

7特斯拉磁共振成像（MRI）通过提供更高的分辨率和更高的信噪比，有可能彻底改变临床成像。然而，7特斯拉MRI存在复杂发射场（B1+）干扰的挑战。并联发射是解决方案，但目前校准并联发射系统的方法速度慢，精度不高。该项目的重点是研究如何在7特斯拉的情况下实现更快、更准确的B1+映射，以应用于大脑和身体。学生将与工业合作伙伴密切合作，设计一个强大的和临床可行的脉冲序列解决方案。此外，将研究基于射频传感器的运动校正方法（例如导频音调和pTx散射），以研究它们在7特斯拉的运动检测和校正中的潜在用途。

7 Tesla magnetic resonance imaging (MRI) has the potential to revolutionise clinical imaging by providing higher resolution and increased SNR. However, 7 Tesla MRI has challenges with complex transmit field (B1+) interference. Parallel transmit is the solution but current methods to calibrate the parallel transmit system can be slow and inaccurate. This project focusses on investigating methods to achieve faster and more accurate B1+ mapping at 7 Tesla for applications in both the brain and the body. The student will work closely with the industrial partner to design a robust and clinically viable pulse sequence solution. In addition, radiofrequency sensor based methods of motion correction (e.g. Pilot Tone and pTx scattering) will be studied to investigate their potential use for motion detection and correction at 7 Tesla.
