GE HEALTHCARE DIRECTION FC091194, REVISION 11 VIVID 7 SERVICE MANUAL 5 - 74 Section 5-4 - Back-End Processor (BEP) 5-4-2 Introduction The Back-End Processor is a computer designed spec ially for the use in the Vivid 7 ultrasound scanners made by GE. The following BEP versions ha ve been used for Vivid 7: • BEP1 was introduced at the in troduction of the Vivid 7 ultrasound scanners in 2001. • BEP2 was introduced September 2002 as a replacement for BEP1, both for new ultrasound scanners from factory and for service replacement in the field. A special BEP4 version is availabl e as replacement unit for BEP2. • BEP2.2 was introduced 2 nd half of 2003 and is used in units with RFI. A special BEP4 version is available as replacement unit for BEP2.2. • BEP3 was introduced with software version v4.0, 2nd half of 2004. Supports the 3D/4D option. • BEP3.2 and BEP4.2 support s Patient I/O with internal USB inte rface. Supports the 3D/4D option. • BEP4.x supports Patient I/O bot h with USB1.1 and USB2.0 interface. MO drive is an option. The BEP4 is delivered in several different variants: - BEP4.3 without 4D for use in new syste ms (introduced with BT’08) (wo/4D). - BEP4.3 with 4D fo r use in new system (intro duced with BT’08) (w/4D). - BEP4.2 without 4D for use in new systems and as a replacement for BEP3.x (wo/4D). - BEP4.2 with 4D for use in new systems and as a replacement for BEP3.x (w/4D). - BEP4 for use as a replacement for BEP2.2. - BEP4 for use as a replacement for BEP2. NOTE: When the descript ions in this section applies only to one or some of the BEPs, it will be marked in the text with BEP1, BEP2, BEP2.2, BEP3, BEP3.2, BEP4.2 or BEP4.3. An “x” as in “BEP3.x” indicates that both BEP3 and BEP3.2 are covered. 5-4-3 Signal Flow and Processing The Back-End Processor receives the data from t he Front-End electronics, stores it in memory, performs scan conversion to pixel dom ain, and drives the system RGB monitor. Back-End Processor software is also processing the Color Flow, Doppler, M-Mode and 4D data. • BEP4.2 without 3D/4D: See Figure 5-46 CPU/Back-End Proc essor Block Diagram (BEP4.2 without 4D) on page 5-77. • BEP4.2 with 3D/4D: See Figure 5-47 BEP4.2 with 4D (R eplacement for BEP3.2 w/4D) - Block Diagram on page 5-78 . • BEP3 without 3D/4D: See Figure 5-50 CPU/Back-End Proc essor Block Diagram (BEP3.2 without 3D) on page 5-81. • BEP3.2 with 3D/4D: See Figure 5-51 CPU/Back-End Pr ocessor Block Diagram (BEP3.2 with 3D) on page 5-82. • BEP3.2 without 3D/4D: See Figure 5-52 CPU/Back-End Pr ocessor Block Diagram (BEP3 without 3D) on page 5-83. • BEP3 with 3D/4D: See Figure 5-53 CPU/Back-End Pr ocessor Block Diagram (BEP3 with 3D) on page 5-84. • BEP2.2: See Figure 5-54 CPU/Back-End Processor Bl ock Diagram (BEP 2.2) on page 5-85. • BEP2: See Figure 5-55 CPU/Back-End Processor Block Diagram (BEP 2) on page 5-86. • BEP1: Figure 5-56 CPU/Back-End Processor Block Diagram (BEP1) on page 5-87 .
