Many patients ask us…What’s the difference?
Benefits of Integrating Dosimetry can include: Faster clearing, less risk of burning, a better chance of successful treatment, lower risk of long term side effects, and a more efficient use of lamps.
Here is how it works… The power output of phototherapy devices varies with age and temperature; up to 50% over a given treatment. Integrating Dosimeters measure the actual light output in real time and adjust the treatment time to give you exactly the programmed dose.
Here is why it is important… If you need to deliver consecutive treatments to different parts of your body, each segment could be delivered a significantly different dose unless you have dosimetry. With time controlled devices, this effect can be reduced by warming up your device, but this takes time and uses valuable lamp hours.
While everyone understands the risks of overdosing (a sunburn), under-dosing can undermine your treatment, as well, by leading to increased photo-adaptation. This is the natural process that makes your skin more tolerant of sunlight. While it protects you from sunburn, in phototherapy it means your skin will require a larger total dose to clear, which in turn increases the risk of long-term side effects. Dosimetry is the means of ensuring exactly the right dose…not too much, not too little.
Timer or dosimeter… Patients have been successfully using timer-controlled devices for decades. They are less expensive and easier to operate. However, Integrating Dosimetry delivers exactly the dose your doctor prescribed without wasteful warm-up time. It is a great assurance that your treatment will progress in the most efficient manner possible.
