So beam area is hard to define and there is no agreement in our industry for defining it.
Dosage expressed as J/cm2 is inadequate
Dosage is usually calculated as Power / Beam Area x Time = J/cm2. However, to consider that dosage should equal J/cm2 is, in my opinion, inadequate.
Let me explain:
Assume there is a well-defined beam area and thus a quantifiable dosage.
Each of these probes apparently apply the same "dosage". However, the total energy delivered is clearly different [10 Joules, 4 Joules and 0.6 Joules respectively].
While dosage appears consistent using J/cm2, I suggest that the clinical results would be quite diverse. So I say that J/cm2 is an inadequate method of expressing dosage.
We are currently working on these issues and will be presenting our conclusions at NAALT in April 2003.
