Second radio transmitting device 106, for receiving the modulated signal, and is demodulated to obtain the high-definition digital letter
Number；
Display 108, shows the high-definition digital signal.
Medical diagnostic equipment 10 is generally used for closely interior high resolution image transmission, so generally without compression, i.e.
Directly obtained high-definition digital signal is transmitted, being wirelessly transferred under 5GHz frequency ranges is realized using above-mentioned each device, has
Effect has ensured the reliability of data transfer, and because the characteristics of 5GHz frequency ranges and used WHDI Radio Transmission Technologys, makes
It possesses transmission without compression and postpones the characteristics of extremely low, contribute to doctor the pathology of patient is made most correct judgement and
Carry out fine manipulation.
In the medical diagnostic equipment 10 of above-described embodiment, the first radio transmitting device 104 sends the medical data collected,
Second radio transmitting device 106 receives the medical data, and is transferred to display 300 and is shown.First radio transmitting device
104 is identical with the structure of the second radio transmitting device 106, under different application scenarios, the function of the two all modules
Emphasize particularly on different fields, the embodiment of the first radio transmitting device 104 and the second radio transmitting device 106 will be in following embodiments
Described in.
