Clinical Evidence

75-120 MHz Four-Channel Power Amplifier

75-120 MHz Four-Channel 1300W solid-state amplifier, independent phase and amplitude adjustment capability. Maximum power output of 0 to 500 watts per channel.

Focused Power

8-port Temperature Monitoring

Track up to 8 independent temperature probes for accurate thermal dosing. Motorized system allows for superior zone mapping. An integrated thermal well ensures easy and accurate temperature calibration of the temperature probes.

Thermal Monitoring

Patient Support System

Hydraulic patient sling allows for the centering of the patient in the applicator.

Positioning and Adjustment

Sigma 60 Applicator

The Sigma 60 is an annular phased array applicator with 8 radiating dipoles, and a bolus membrane. The largest in the series with a 60cm opening. Advanced annular phased array principles create a central focusing of energy, which reduces the penetration losses of the energy radiated into the body.

Larger Patient Size

Sigma Ellipse

The Sigma Ellipse is an annular phased array applicator with 8 radiating dipoles, and a bolus membrane. The Sigma Ellipse provides improved comfort for smaller size patients. Applicator can be swapped out for different sizes.

Standard Applicator

Sigma 30

The Sigma 30 is an annular phased array applicator designed for limbs. This applicator has also been used for Pediatric cancer treatment

Limbs / Pediatric

Control Panel

Easy to use controls for patient positioning and bolus water fill/circulation

Ease of Use

Water Circulation System

Provides constant volume water supply to the Applicator Bolus with temperature range of 5 °C to 45 °C.

Patient Comfort

24″ Medical Grade Touch Screen Monitor

High resolution monitor providing easy access to user control systems for improved patient monitoring and system control.

Ease of Operation

Color Printer

The BSD‑2000 computer system includes a wireless printer, keyboard/mouse, and USB ports for the offloading of patient records. (model subject to change)

The Sigma Treatment Base Unit

  • RF power delivery subsystem.
  • Proprietary, thermistor-based, thermometry subsystems.
  • Computerized monitoring and control subsystems.
  • Applicator subsystem that includes an applicator and patient support system.
  • Various accessories, including a tissue equivalent QA lamp phantom that provides verification of the energy focus, pattern steering, and system operations.

The standard BSD‑2000 has a maximum power output of 1300 watts. Currently sold throughout the U.S., Europe and Asia. And in the U.S. only under FDA sanctioned device exemption.

Annular Phase Array

The Sigma applicators are annular phased array applicators that are comprised of a clear plastic shell, 8 radiating dipoles, and a bolus membrane. The Sigma Ellipse provides improved comfort for smaller sized patients.

Cooling System

Water system automatically fills the bolus and controls the bolus water temperature. This keeps patient exterior at comfortable temperature range.

Fabric Sling

Fabric sling comfortably supports patient inside the applicator for optimized patient comfort. Hydraulic lift system used for optimal positioning

Quick Drain Bolus

Quick drain capability allows fast access to the patient – 15 seconds for patient access and 30 seconds for a complete drain.

Sigma System

Three Interchangeable phased array applicators to support different patient sizes and indication specific applications.

Intuitive Interface

Full featureed, user friendly, intuitive, graphical user interface. Touch screen with step-by-step guide for setup and treatment procedure. Primary user features presented on main screen.


Closed-loop feedback system with automatic monitoring and control of treatment parameters, including power output, frequency, amplitude & phase, tissue & core temperature, and treatment time.

Temp. Control

Control of power and tissue temperature to within ±0.1 °C in compliance with ESHO guidelines. Data regarding temperatures, RF power level, and RF power control updated every 2 seconds.

Safety Checks

The computer automatically performs safety checks to ensure proper operation of the system and ensure patient protections with auto shutdown features.

Phase & Amplitude

Solid-state amplifier with 4-channel independent phase and amplitude adjustment capability

500W per Channel

Maximum power output of 0 to 500 watts per channel. Phase accuracy within a 10 degree tolerance.

Phase Offset

Computer automatically monitors and controls forward and reflected power, phase, and power on each channel.

Treatment Plan

Optimized treatment settings are calculated through the use of treatment planning software tools provided with the system.

High Accuracy

Non-perturbing, electromagnetically insensitive, temperature sensors with an accuracy of ±0.2 °C over a range of 25 to 52 °C.

Auto Positioning

Automated positioning system allows the operator to map the sensor along the length of the catheter in order to determine the temperature profile.

Precise Calibration

Precise calibration reference sensor is accurate to ±0.05 °C over a range of 0 to 60 °C. New Thermal well for easy pre-treatment calibration.

Probe Mapping

Motorized probe mapping allows for the mapping of temperature in 0.5 cm increments along catheter path.
