If you don't get the neurotherm, you are ******ed (was that too strong?)
It is the only machine I am aware of that allows you to hold steady your "dose" during pulsed RF. Why would you not want to maintain the same electrical field during pulsed RF. Every other machine only holds temp constant (which has nothing to do with the effect you are trying to achieve) and voltage goes all over the place during treatment, and usually is way to low.
People say pulsed doesn't work? It probably doesn't if your voltage was 10-20 and was changing during the whole pulsed sequence.
Get the neurotherm and do it right. Hold voltage constant. Be a man and so you can say - "I produced this type of electrical field that remained constant for this amount of time!"
The rest of us, if we were asked - "well what dose did you give during your pulsed treatment? What was the state of the electrical field?" We will have to answer - "Hell if I know. At least the temperature stayed at 42C."
Actually, the top of the line Cosman unit has the same feature. They call it "E-Dose." It may even be more advanced than the Neurotherm Pulsed Dose feature, as I don't think Neurotherm allows variation of pulse width, rate, whilst maintaining constant voltage, but could be wrong.
"Pulsed RF (480 kHz carrier frequency)
Auto Temperature: Off, 3795°C
Auto Timer: 5 sec 30 min
Voltage: 0-100 Volts Peak
Rates: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 Hz
Widths/Durations: 2, 3, ... , 30 msec
E-dose: Control Voltage or Pulse Width"
Of course, all of this could have absolutely zero relevance as we have no idea which settings for pulsed RF are best, and the literature is still poor on pulsed RF.
