Using a Doppler ultrasound device, fetal heartbeats can be detected by the twelfth week of pregnancy.

B) Fetal heartbeats can be detected by the twelfth week of pregnancy, using a Doppler ultrasound device.

Why is B wrong? I can separate it into two sentences: 1) Fetal heartbeats can be detected by the 12th week of pregnancy. 2) Fetal heartbeats can be detected using a Doppler ultrasound device. Both seems okay. The OG answer said it must be a physician who is using the device but can't it be implicit?

LZ觉得"Fetal heartbeats use a Doppler ultrasoud device"合逻辑吗？
