Left-side Modules:

  1. Battery Management System: Manages the battery power supply to provide electricity for the equipment (the green arrow indicates the power path).
  2. User Interface: Connects to LCD/LED (for displaying images and parameters) and audio (for operation prompts and feedback) to realize human-computer interaction.
  3. USB Interface: Handles USB 2.0 data transmission (such as image storage and device configuration).
  4. Wireless Interface: Supports wireless data transmission (such as Wi-Fi) to realize remote control or data sharing.

Right-side Modules (Ultrasonic Signal Chain):

  1. Beamforming Control: Optimizes the direction and focusing of the ultrasonic beam to improve imaging resolution.
  2. High-Voltage Pulse Generator (HV pulse generator): Generates high-voltage pulses to drive the transducer to emit ultrasonic waves.
  3. Analog Front-end: Receives the echo signals from the transducer and performs analog processing such as amplification and filtering.
  4. Transducer: Converts electrical signals into ultrasonic waves (for emission) and converts echoes into electrical signals (for reception), and is in direct contact with the patient.
