4-8 Product Principle
4.3.1 PC Module
PC module aggregates CPU, iGPU (core graphics/integrated graphics), host bridge (IO extension),
memory bank, network adaptor, etc. Together with PC carrier board and hard disk, as the
calculation and control center of the entire unit, PC module fulfills the comprehensive functions on
the computer system.
The processer of DC-70 is Intel Celeron 1020E QM77; the memory capacity is DDR3L, which is 4
GB.
4.3.2 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 V3.0 version adopts the GTX970M image processor made by
Nvidia, which is installed on the assembly box of the back-end PC in the form of MXM module.
4.3.3 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.
4.3.4 Wireless Network Module
Wireless network module fulfills wireless communication. It supports Wi-Fi, 802.11b/g/n, and adopts
M.2 PCI-Express Mini standard.
