Sell (Lot of 4Pcs-J5) Used Philips HD11XE Parts Board

The Philips HD11XE is a versatile diagnostic ultrasound system widely used in radiology, obstetrics, and cardiology. At the heart of its performance lies a series of modular parts boards, each playing a critical role in image generation, signal processing, and system control. Here, we explore the major types of boards used in the HD11XE system and how they function.

1. Beamformer Board

The beamformer board is responsible for controlling the transmit and receive operations of ultrasound waves. It synchronizes the activation of piezoelectric elements in the transducer to shape the ultrasound beam and focus it at specific depths. On the receive side, it performs dynamic focusing and delays to reconstruct the returning echoes into coherent signals. This board is key to producing high-resolution images.

2. ADC/DSP Board (Analog-to-Digital Converter / Digital Signal Processor)

Once analog echoes are received, the ADC/DSP board converts them into digital signals. It also handles preprocessing, including filtering, gain control, and demodulation. The digital signal processor plays a key role in real-time signal enhancement and image formation, directly impacting image clarity and diagnostic accuracy.

3. Control Board / System Controller

The control board manages the overall coordination of system components. It interfaces with user inputs (keyboard, trackball, touch controls) and issues commands to other boards. It also handles boot-up sequences, software updates, and hardware diagnostics, ensuring system stability.

4. Power Supply Board

This board converts AC power into multiple regulated DC voltages needed by other boards and components. It incorporates protection circuits to safeguard against voltage spikes and overheating, contributing to long-term reliability.

5. Display Controller / Video Board

Responsible for rendering the processed ultrasound image on the monitor, the video board manages frame buffering, scaling, and grayscale/color mapping. It ensures smooth, real-time display of ultrasound data and supports video outputs for external monitors or printers.

6. I/O Interface Board

The I/O board manages communication between external devices (USB, DICOM networks, footswitches, printers) and the system. It is essential for data transfer, storage, and network integration, especially in PACS environments.

Functional Principle Summary

Each board in the Philips HD11XE is modular, allowing for ease of maintenance and upgrades. Their functions are highly synchronized—starting from the generation and focusing of ultrasound pulses to the real-time image display and data output. This synergy between hardware modules enables the HD11XE to deliver fast, precise, and user-friendly ultrasound imaging.
