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 comes in two configurations, a lower power basic system (BSD-2000B) that has a maximum power output of 1300 watts and an upgraded higher power system (BSD-2000U) that has a maximum power output of 1800 watts. Currently sold throughout the U.S., Europe and Asia. And in the U.S. only under FDA sanctioned device exemption.

Annular Phased 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.

Quick Drain Capability

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

Sigma System

Interchangeable phased array applicators to support different patient sizes.

Intuitive Interface

User friendly, intuitive, color graphics interface.
Step-by-step guide for setup and treatment procedure.

Automatic Monitoring

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

Temperature Control

Control of power and tissue temperature to within ±0.1°C.
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 safety

Independent Phase & Amplitude

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

500 watts per Channel

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

Controlled Phase Offset

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

Treatment Planning Software

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.

Automated 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.

Real-time MR Image Guided

The BSD-2000 3D and 3D/MRI (non-US) employs real-time MR image guided non-invasive thermometry using proton resonance frequency shift measurements, accurate within ±0.5˚C.
