4-10 Product Principle
After EAF518F, the functions of the PC module and the PC carrier board are integrated on the same
board, which is called the PC carrier board CPU module.
The new PC processer is pentium G5400; the memory capacity is DDR4, which is 8 GB.
The SSD interface type is changed from mSATA to M.2.
4.3.3 GPU Module
As a co-processor of the back-end processing unit, the GPU module is mainly used for
co-processing the image operation of 3D/ 4D imaging. It realizes the 3D/ 4D imaging together with
the CPU module.
The DC-70 ultrasound system in V4.0 version adopts the GTX 1050Ti image processor made by
Nvidia, which is installed on the assembly box of the back-end PC in the form of MXM module.
4.3.4 Storage Device
Internal storage device: is used to save the operation system, application programs, image data
and user data.
External storage device: is used to interact and back up the image data.
The hard disk embedded inside DC-70 V4.0 is 2.5 inches, the capacity of which is 1T. External
storage device adopts tray-like drive and supports DVD burning.
