Abstract
The invention discloses medical wireless WIFI transmission type B ultrasound equipment and a data transmission method. The B ultrasound equipment comprises a shell body, a probe, a WIFI module, an inner antenna, an antenna connector, an FPGA chip, a receiving chip, an emitting chip, an upper lid and a main machine. Because the equipment only comprises the emitting chip, receiving chip and the FPGA chip for the simple signal processing and wave beam synthesis, the part related to large amount of information processing is transplanted to the main machine. The strong capacity of the main machine can make more image processing to ensure the good image quality and guarantee that the clinical doctor can give the correct diagnosis. Because the WIFI transmission is limited in data amount, the signal transmission is completed by using eight data transmission channels. The arrangement of the patch antenna increases the transmission power of the wire WIFI. The detachable probe can be replaced by different types of probes which are suited for different parts of the human body. The diagnosis results are more accurate, have more reference value, and at the same time, the product service life is prolonged.
