Investigations of cabin design in UV phototherapy.

Purpose: UVR phototherapy cabins exist in a huge variety of configurations and geometries. An accurate dose model has been developed which can be used to examine the question of cabin design to investigate factors influencing dose on a patient.

Methods: This work extends the existing dose model to entire cabins and investigates how cabin and reflector geometry influence resultant dose.

Results: The model predictions are in line with what is measured. It is found that the length and angle of the reflectors have a large influence on received dose.

Conclusions: The influence of cabin geometry is important in estimating patient dose, and the findings of this work are applicable to future cabin designs.
