Doppler frequencies of 7–12 MHz and 4–8 MHz should be applied for the temporal and for the extracranial supra-aortic arteries, respectively. PRF should be 2–3.5 kHz and 3–4 kHz, respectively. The angle between sound waves and artery should be ≤60°
多普勒频率7-12 MHz和4-8 MHz应分别应用于颞动脉和颅外主动脉上动脉。 PRF应分别为2-3.5 kHz和3-4 kHz。 声波与动脉之间的夹角应≤60°
1、the extracranial supra-aortic arteries如何翻译?
2、the extracranial supra-aortic arteries和the supra-aortic arteries有什么区别?
