摘要
提出了胶囊内窥镜系统及其无线图像传输子系统的设计原则,确定了基于射频芯片RF2510和RF2917的设计方案。根据电磁波传播理论,计算了胶囊在人体内发射的电磁波信号穿透人体后的达到接收器时的场强值,结果表明,体外信号强度可以达到接收的要求,从而验证了该方案的可行性。
The design fundamental and the wireless image transmission subsystem of the capsule endoscopy （CE） axe proposed. Then a scheme based on RF chips, RF2510 and RF2917, is given. To validate the feasibility of this scheme, this paper calculated the attenuation of the signal transmitted from CE. The result shows that the signal is still strong enough for the receiver to receive after it is absorbed by the human body tissues when the signal propogate in human body.
