Deep Regional system using an annular phased array configuration to shape and focus
thermal energy on targeted treatment area deep inside the limbs, pelvis, abdomen or thorax.

  • BSD-2000 Features

    • Clinically Proven in Phase III studies
    • Industry Leader in Hyperthermia
    • FDA (HDE) Approved for the
      treatment of cervical tumors
  • 24” Medical Grade Touch Screen Monitor

    High resolution monitor providing easy access to user control systems for improved patient monitoring and system control.
  • 8-port Temperature Monitoring

    Track up to 8 independent temperature probes (31 sensor locations per probe) for accurate thermal dosing. Motorized system allows for superior zone mapping. An integrated thermal well ensures easy and accurate temperature calibration.
  • 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.
  • 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)
  • 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 significantly overcomes the penetration losses of the energy radiated into the body.
  • Sigma 30

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

    Provides constant volume water supply to the Applicator Bolus with temperature range of 5 ̊C to 45 ̊C.
  • Patient Support System

    Hydraulic patient sling allows for the centering of the patient in the applicator.
  • Control Panel

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

    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 temp., 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.
