The PTW semiconductor probes for in-vivo dosimetry are fixed to the
patient's body to measure the patient skin, entrance or exit dose during
external radiation treatments. Up to twelve detectors can be connected
to the detector con-nection box and read simultaneously by a VIVODOS
or MULTIDOS multi channel dosemeter.
VIVODOS E accepts up to four detectors to be connected directly to the rear panel. Three different detector
types with integrated build-up caps for photon energies from Co-60 to 25 MV and one type for electron
measurements are available. The detectors do not require a bias voltage. They have a connection cable of
3 m or 4 m length with BNC connector. In-vivo dosimetry during total body irradiation (TBI) makes it possible
to calculate the midline dose, which is needed for correct treatment.
Measure patient dose during external radiotherapy
Suitable for any irradiation technique including TBI
Four types for different beam qualities are available
Comply with safety standard IEC 60601-2-9
