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.
