PTx Suppression Heating Test 1

Temperature probe measurements for heating at tip of wire 12 cm long copper wire in a polyacrylic acid cylindrical phantom (radius = 9 cm, height = 24 cm) using FRFSE sequence (TR = 559 ms, TE = 100 ms, echo train length = 24, 1 slice, imaging time = 4:08). Excitation with 4-element parallel transmit coil with phase shifts of 40, 16, 200 and 301 degrees (suppression mode) with a transmit gain of 190

本数据集为温度探针测量实验数据，针对置于聚丙烯酸圆柱形体模（半径9cm，高度24cm）内的12cm长铜导线尖端的加热过程开展测量。实验采用FRFSE（Fast Recovery Fast Spin Echo，快速恢复快速自旋回波）序列进行扫描，序列参数如下：重复时间（TR）=559ms，回波时间（TE）=100ms，回波链长度=24，单切片采集，成像时长为4分08秒。实验采用四单元并行发射线圈进行射频激励，各线圈单元的相移分别为40°、16°、200°及301°（工作于抑制模式），发射增益设置为190。
