July 21, 2009 - Elekta and C-RAD have reached an agreement where the Sentinel laser scanner system has been selected as the Elekta preferred solution for optical surface tracking. Elekta’s customers will be offered this technology for patient positioning and intrafraction motion detection without the use of markers.
Elekta has chosen to partner with the C-RAD Sentinel for its advanced laser-camera based system that can be used for multiple applications within the field of radiation therapy. In contrast to alternative approaches, by using advanced laser surface scanning technology the need for implanted or even surface located reference markers is avoided. This approach delivers workflow efficiencies for the clinic and greater comfort for the patient.
The Sentinel System solution for intra fraction motion monitoring can be used in combination with the HexaPOD evo RT system. It identifies patient movements during the treatment. The patient error correction values obtained by the Sentinel scan can then be utilized by iGUIDE to reposition the patient.
According to the agreement, the Sentinel system is now being made available through the Elekta sales and distribution network to Elekta customers worldwide.
