Partially Delivered Prescribed Dose
Whenever the irradiation is stopped either by the Radiation Therapy Technologist
(RTT) or the system or other means, whereby the prescribed dose is only partially
delivered, a system message appears to inform you explicitly of any such partial
delivery.
Note: Several kinds of ‘partial’ warnings exist. Figure 37-2 represents one example.
Figure 37-2. Partial Delivery - System Message
Error Message “Delivered MU of layer should
be less than prescribed MU”
The complete error message typically reads Delivered MU of layer should
be less than prescribed MU 0,288 of *(1+0.05) in BeamResult
layer 32.
At the end of irradiation, the delivered MU for each layer is compared with the
prescription (in the above case 0.288MU for layer 32).
WARNING The Radiation Therapy Technologist (RTT) must be aware of the
progress of the treatment at all times.
WARNING As a Radiation Therapy Technologist (RTT) you are recommended to
monitor the patient behavior during irradiation. In case of patient
movement, pause the beam immediately.
