Description

technical field [0001] The invention relates to a data transmission system of digital medical imaging equipment. In particular, it relates to a data transmission system of digital medical imaging equipment based on optical fiber communication. Background technique [0002] Digital medical imaging equipment usually consists of image sensors, data sending modules, data receiving modules, data processing and display modules. The common form is that medical imaging equipment includes image sensors and data sending modules, and external computers include data receiving modules and data processing modules. Like the display module, the medical imaging device transmits data to the computer through some kind of high-speed data interface. [0003] With the improvement of imaging resolution and frame rate of image sensors, the amount of raw image data obtained by imaging devices is increasing. The image output methods of imaging devices can be divided into two categories: compression...

Problems solved by technology

When transmitting data through Gigabit Ethernet, due to the overhead of network protocols and the delay of hardware processing data packets, generally only stable and reliable data transmission of about 600 Mbps can be achieved. It can be seen that the Gigabit Ethernet interface cannot meet the real-time requirements of this image sensor. Data Transfer Requirements

The C10500D-42 sensor newly launched by HAMAMATSU is equipped with a Gigabit Ethernet interface, but the sensor has only one port to output data, and the highest data rate is reduced to 420Mbps, at the cost of reducing the imaging resolution (the resolution of C10502D is 2268x60, The resolution of C10500D-42 is 1480x60)
