Solid Performance
MA-151 Wave Guide Applicator

MA-151: mini-dual ridge wave guide applicators have an aperture of 4 x 5 cm and individual heating patterns approximately 2.5 x 2.5 cm by 2 cm deep. Advanced annular phased array principles create a central focusing of energy, which significantly overcomes the penetration losses of the energy radiated into the body.
MA-100 Wave Guide Applicator

MA-100: side loaded wave guide applicators have a 10 x 13 cm aperture and a heating pattern approximately 8 x 10 cm by 2.5 cm deep.
Wave Guide Applicator

MA-120: side-loaded wave guide applicator has an 18 x 24 cm aperture and a heating pattern of approxi- mately 12.5 x 19.5 cm by 2.5 cm deep.
Probe Calibration

The Thermal Calibration Well can be used to quickly verify probe accuracy prior to treatment

Ease of Use
Brachytherapy Treatment Support

Interstitial hyperthermia delivers heat directly to the site of the tumor via brachytherapy catheter. The microwave power delivered to the antennas (available as an optional kit) can be adjusted in amplitude and phase to conform the heating pattern to the tumor.

Versatility
The BSD-500 offers two USB ports for the offloading of patient records and keyboard/mouse. The system includes a wireless color printer. (model subject to change)
Water Circulation System

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

RF Depth Control
915 MHz Eight-Channel Power Amplifier

915 MHz Eight-Channel Power Amplifier Multi-channel solid state amplifier producing an available 480 Watts of RF power, (60 watts per channel) independently adjustable phase and amplitude.

Focused Power
Interchangeable Superficial Applicators

Applicators available in multiple configurations to treat a range of tumor sizes and locations. Base model includes the MA-100 wave guide as shown.

Focused Treatment Area
MA-251 Microwave Interstitial Antenna

The semi-rigid MA-251 microwave interstitial applicators can be inserted into 15.5 gauge (5 French) radiation implant catheters. The heat- ing pattern is ellipsoidal and approximately 4.5 cm in length along the applicator shaft with heating to the applicator tip.

BSD-500 Specs

Solid State Generator
The BSD 500 microwave hyperthermia system is equipped with a 915 MHz power generator. The solid state generator has 8 channels which can be independently adjusted in phase and amplitude.

Up to 24 Interstitial Applicators
The 8 channel generator feeds into a 3 way power splitter allowing up to 24 applicators to be connected. Each antenna produces a radiant energy zone that can be arranged to shape a heat zone specific to the tumor.

Up to 400 watts
The system itself is portable, space efficient and produces up to 400 watts of microwave energy in a single channel mode and up to 60 watts per channel in the eight channel mode. A high resolution touch-screen display is used for treatment planning, setup and monitoring during the procedure.

Treats Recurrent Cancer
Superficial hyperthermia is used to non-invasively treat recurrent or progressive cancerous tumors located within a few centimeters of the surface of the body. Interstitial hyperthermia is used to treat recurrent or progressive cancerous tumors located below the skins surface.

MA-251 Interstitial Antenna

The semi-rigid MA-251 microwave interstitial applicators can be inserted into 15.5 gauge (5 French) radiation implant catheters. The heating pattern is ellipsoidal and approximately 4.5 cm in length along the applicator shaft with heating to the applicator tip.
No Shielding Required
Output frequency of 915 MHz (ISM frequency, requires no RF shielded enclosure) 8 independent channels deliver 0 to 60 watts of power. The forward power of all 8 channels are monitored, controlled and displayed by the computer.

Synchronous or Asynchronous
The computer will monitor and display the reflected power for each channel. In the synchronous mode, all 8 channels are driven by the same signal.

Controlled Phase Offset
The asynchronous mode allows each channel to be driven by independent sources. The power balance and phase offset of each channel is software controlled using the touch screen monitor.

Channel Multiplexer
All eight channels can be multiplexed into a single output channel of 0 to 400 watts under computer control. The forward and reflected power from each of the 8 channels are summed together and displayed as total power.
Water Circulation System
Constant volume water supply
Bolus temperature controller with a temperature range of 5 °C to 45 ° C

Calibration
Integrated thermal well
Standard NBS traceable temperature probe
accurate within 0.10 °C.

Power
115 - 230 VAC +/- 10%, 50 - 60 Hz
Current consumption <15 amps
Four Sensors
Four sensors are provided with the basic system. The interface accepts up to 8 sensors. A typical treatment set-up would utilize 12 to 15 ports for the microwave interstitial applicators and 1 to 4 ports for connections to the temperature sensors.

Non-Mettalic Leads
Temperatures are displayed with resolution of 0.1 °C. - CK Inherently stable thermistor type sensors with non-metallic leads. These sensors are not perturbed by the microwave fields generated in the BSD500 system.

Fits 15.5ga Catheter
The sensor diameter is approximately 1.1 mm and is located at the end of a 33 cm (13 in.) sealed high resistive lead.

Low Leakage
An extension cable is provided with a length approximately 2.1 m (7ft). Leakage currents are guaranteed to be less than 15 micro amps for any type of failure.

Treatment Planning Software

Performing interstitial hyperthermia requires the use for the BSD-500 built-in treatment planning program. Using this software, the size and shape of the tumor can be traced on a grid on the computers screen. Treatment plans can ten be made by simulating the placement of antennae in and around the tumor. The power and phase of each channel can be set and adjusted on the screen. Each change in placement, power or phase will display the new simulated heating pattern. Watch Demo
