Aloka 3500 manual

The Aloka 3500 is a high-performance ultrasound system that offers advanced features and functions for various clinical applications. This article will provide an overview of the Aloka 3500 manual, including its specifications, features, operation, and maintenance.


The Aloka 3500 has the following specifications:

Download Zip:

  • Dimensions: 560 (W) x 900 (D) x 1400 (H) mm

  • Weight: 95 kg (main unit), 15 kg (monitor)

  • Power supply: AC 100-240 V, 50/60 Hz

  • Power consumption: 800 VA (max)

  • Display: 15-inch LCD monitor with tilt and swivel functions

  • Probe connectors: 3 active ports

  • Hard disk: 160 GB

  • DVD drive: DVD-RAM/-R/-RW/+R/+RW

  • Printer: Optional external printer

  • Network: Ethernet, DICOM 3.0 compatible


The Aloka 3500 incorporates key features of the Aloka ProSound series, such as:

  • Quint Frequency Imaging: Select up to five frequencies for grayscale imaging and Doppler. This allows for optimal resolution and penetration for different tissues and depths.

  • Tissue Harmonic Echo: Enhance the image quality by suppressing noise and artifacts, especially for obese or difficult-to-examine patients. This feature also improves the contrast resolution and edge detection.

  • Multibeam Processing: Increase the frame rate by transmitting and receiving multiple beams simultaneously. This feature enables smooth and clear visualization of moving structures, such as the fetal heart.

  • Dual Dynamic Display: Compare two images side by side on the same screen. This feature allows for easy comparison of different modes, such as B-mode and Doppler, or different time points, such as before and after contrast injection.

  • Angular M-mode: Measure the motion of structures along any direction. This feature is useful for assessing the cardiac function and wall motion.

  • Real-time 3D/4D imaging: Acquire and display three-dimensional images in real time. This feature provides a realistic and detailed view of the anatomy, such as the fetal face or the heart valves.


The Aloka 3500 has an ergonomic and user-friendly design that enables easy operation. The main components of the operation panel are:

  • Trackball: Move the cursor on the screen and select items from menus and submenus.

  • Function keys: Access various functions, such as mode selection, image freeze, cine loop, measurement, calculation, annotation, etc.

  • Alphanumeric keyboard: Enter patient information, comments, labels, etc.

  • Rotary knobs: Adjust parameters, such as gain, depth, focus, etc.

  • Touch screen: Touch icons on the screen to activate or deactivate functions, such as presets, body marks, image optimization, etc.

To perform an ultrasound examination with the Aloka 3500, follow these steps:

  • Turn on the main unit and the monitor.

  • Select a probe and connect it to one of the probe ports.

  • Select a preset that matches the probe type and the examination region.

  • Enter the patient information using the keyboard or the touch screen.

  • Apply ultrasound gel to the probe and place it on the patient's body.

  • Adjust the image quality using the rotary knobs or the touch screen.

  • Select a mode from B-mode, M-mode, Doppler, or 3D/4D using the function keys.

  • Freeze the image using the function key or the probe switch.

  • Perform measurements, calculations, annotations, etc. using the function keys and the trackball.

  • Save the image or the cine loop to the hard disk, the DVD drive, or the network using the function key or the touch screen.

  • Print the image using the external printer if available.

  • End the examination and clear the patient information.


The Aloka 3500 requires regular maintenance to ensure its proper functioning and safety. The maintenance procedures include:

  • Cleaning: Clean the main unit, the monitor, the probes, and the accessories with a soft cloth moistened with water or a mild detergent. Do not use organic solvents, such as alcohol, acetone, or benzene. Do not spray any liquid directly on the system. Do not immerse the probes in water or any other liquid.

  • Disinfection: Disinfect the probes and the accessories that come in contact with the patient's body with a disinfectant approved by Aloka. Follow the instructions of the disinfectant manufacturer. Do not use disinfectants that contain phenol, glutaraldehyde, or chlorine.

  • Inspection: Inspect the system for any damage, such as cracks, scratches, dents, or loose parts. Check the power cord and the probe cables for any wear or tear. Check the operation panel and the monitor for any malfunction or abnormality. If any problem is found, contact Aloka or an authorized service representative.

  • Calibration: Calibrate the system periodically to ensure its accuracy and performance. Calibration can be performed by Aloka or an authorized service representative. Calibration includes adjusting the system clock, checking the image quality, verifying the measurement accuracy, etc.
