The Microprocessor Based 1 & 3 MHz Ultrasonic Physiotherapy Machine is a professional therapeutic ultrasound device designed for physiotherapy clinics, rehabilitation centres, hospitals, sports therapy centres, and other healthcare facilities. It combines microprocessor-based control with dual-frequency 1 MHz and 3 MHz ultrasonic therapy, providing flexibility for different treatment depths and clinical applications.
The 1 MHz frequency is generally selected when treatment of relatively deeper tissues is required, while 3 MHz is typically preferred for more superficial tissues. Treatment parameters should always be selected according to professional assessment and the patient’s individual requirements.

PHYSIOMODALITIES™ provides physiotherapy equipment designed for practical clinical use, with a focus on convenient controls, reliable operation, and professional rehabilitation applications.
What Is a Microprocessor Based 1 & 3 MHz Ultrasonic Physiotherapy Machine?
A Microprocessor Based 1 & 3 MHz Ultrasonic Physiotherapy Machine is an electronic therapeutic ultrasound unit that uses a microprocessor-controlled system to manage available treatment parameters.
The dual-frequency configuration allows the physiotherapist to select between 1 MHz and 3 MHz according to the intended treatment depth and clinical protocol.
The machine uses an ultrasonic applicator with suitable coupling gel to transfer acoustic energy to the selected treatment area.
How Does It Work?
Therapeutic ultrasound uses high-frequency acoustic energy delivered through an applicator placed over the treatment area.
During a typical session:

- The physiotherapist assesses the patient and selects the treatment area.
- The skin is prepared before treatment.
- Appropriate ultrasonic coupling gel is applied.
- The required frequency is selected.
- Treatment intensity and other available parameters are adjusted.
- The applicator is moved over the treatment area using the recommended technique.
- The patient is monitored throughout the session.
- The treatment is stopped after the selected time.
1 MHz Frequency
1 MHz is generally associated with treatment of relatively deeper tissues and may be selected when a greater treatment depth is required.
3 MHz Frequency
3 MHz is generally associated with more superficial tissues and may be selected when a shallower treatment depth is appropriate.
Key Features
Dual Frequency: 1 MHz & 3 MHz
The machine provides two commonly used therapeutic ultrasound frequencies, giving the physiotherapist greater flexibility when selecting treatment parameters.
Microprocessor-Based Control
Microprocessor-based operation allows available treatment parameters to be managed electronically and provides a convenient interface for professional use.
Digital Display
The digital display helps the operator monitor selected treatment settings during the therapy session.

Adjustable Treatment Parameters
Available intensity, mode, and treatment duration can be adjusted according to the machine configuration and prescribed treatment protocol.
Continuous & Pulsed Therapy
Ultrasonic therapy machines may provide continuous and pulsed operating modes, allowing professionals to select the appropriate mode according to the treatment requirement.
Digital Timer
A treatment timer helps control the duration of each therapy session and supports consistent treatment procedures.
Professional Ultrasonic Applicator
The applicator is designed to deliver ultrasonic energy to the selected treatment area when used with an appropriate coupling medium.
Applications
The Microprocessor Based 1 & 3 MHz Ultrasonic Physiotherapy Machine may be incorporated into professional physiotherapy and rehabilitation programs for:
- Soft-tissue rehabilitation
- Muscle stiffness
- Sports injury rehabilitation
- Joint-related rehabilitation
- Tendon and ligament rehabilitation
- Muscle strains
- Selected post-injury rehabilitation programs
- Superficial and deeper tissue treatment protocols
- General therapeutic ultrasound applications
The machine should be used only when therapeutic ultrasound is appropriate for the individual patient.
Benefits
Dual-Frequency Flexibility
Having both 1 MHz and 3 MHz frequencies in one unit allows the therapist to select the frequency appropriate for the intended treatment depth.
Microprocessor-Based Operation
Electronic control helps provide convenient management of available therapy settings.
Professional Clinical Use
The machine is suitable for physiotherapy clinics, rehabilitation centres, hospitals, and sports rehabilitation facilities.

Consistent Treatment Timing
The digital timer helps maintain the planned duration of each treatment session.
Easy Parameter Monitoring
Digital controls and display indicators make it easier for trained operators to monitor the selected settings.
Practical Physiotherapy Equipment
The combination of dual-frequency ultrasound and digital control makes the unit a versatile addition to a professional physiotherapy setup.
How to Use the Machine
Step 1: Inspect the Equipment
Check the main unit, applicator, cable, and controls before starting treatment.
Step 2: Prepare the Treatment Area
Position the patient comfortably and prepare the selected treatment area.
Step 3: Apply Coupling Gel
Apply suitable ultrasonic coupling gel evenly over the treatment area.
Step 4: Select the Frequency
Choose 1 MHz or 3 MHz according to the prescribed treatment protocol.

Step 5: Set Treatment Parameters
Select the appropriate intensity, mode, and treatment duration available on the machine.
Step 6: Start Treatment
Place the applicator properly against the gel-covered treatment area and begin therapy.
Step 7: Move the Applicator
Move the applicator using the technique recommended by the manufacturer and qualified physiotherapist.
Step 8: Monitor the Patient
Observe patient comfort throughout the session and modify or stop treatment if unexpected discomfort occurs.
Step 9: Complete Treatment
Stop the output, remove the applicator, clean away the coupling gel, and clean the applicator according to the manufacturer’s instructions.
Safety Precautions
- Operate the equipment only according to the manufacturer’s instructions.
- The machine should be used by appropriately trained healthcare professionals.
- Always use a suitable coupling medium during ultrasonic treatment.
- Do not use the applicator over damaged skin unless specifically directed by a qualified healthcare professional.
- Follow contraindications and precautions associated with therapeutic ultrasound.
- Avoid treating areas where ultrasound therapy is not appropriate.
- Inspect the applicator and cable before every treatment.
- Do not operate the machine with wet hands.
- Keep the main unit away from water and excessive moisture.
- Stop treatment if the patient experiences unusual pain, excessive heat, or other unexpected symptoms.
