Figure 1From: Intra-fraction setup variability: IR optical localization vs. X-ray imaging in a hypofractionated patient populationPatient set up and immobilization. Panel A, patient setup for cranial treatment. The thermoplastic mask is fitted with 7 IR markers for stereotactic localization. Panel B, patient setup for body treatments. A vacuum cushion is modeled on the subject who lies aided by an arm support. For body treatments a leg support device is also used for immobilization purposes. In both cases, markers are placed on patient's skin with a biocompatible tape.Back to article page
