What Is DIGI Ultrasonic 1 & 3 MHz Physiotherapy Machine?
The DIGI Ultrasonic 1 & 3 MHz Physiotherapy Machine is a dual-frequency therapeutic ultrasound unit that delivers ultrasonic energy through a dedicated therapy applicator.
The two frequency options provide flexibility in treatment:
- 1 MHz is generally associated with relatively deeper tissue treatment.
- 3 MHz is generally associated with more superficial tissue treatment.
The appropriate frequency, intensity, treatment time, and technique should always be selected by a qualified physiotherapist according to the patient’s condition.

How Does Ultrasonic Therapy Work?
Therapeutic ultrasound uses high-frequency acoustic energy delivered through an applicator. A suitable coupling gel is applied between the applicator and skin to facilitate effective energy transfer.
A typical treatment session involves:
- Assessing the patient and selecting the treatment area.
- Preparing the skin.
- Applying suitable ultrasonic coupling gel.
- Selecting 1 MHz or 3 MHz frequency.
- Setting the required treatment parameters.
- Applying the ultrasonic applicator to the treatment area.
- Moving the applicator using the recommended technique.
- Monitoring the patient during treatment.
- Completing the session and cleaning the applicator.
