CIRS 038立體定向模體,CIRS 038模體英文介紹： SRS commissioning and treatment verification Stereotactic Radiosurgery (SRS) necessitates a high degree of accuracy in target localization and dose delivery. Small errors can result in significant under treatment of portions of the tumor volume and overdose of nearby normal tissues. The CIRS Stereotactic End-to-End Verification Phantom “Steev” provides a means to check every step the patient will undergo in the treatment process-- from diagnostic imaging with CT, MR and PET, to treatment plan verification.
Accurate patient simulation Steev’s anthropomorphic exterior allows for use of multiple bing and fixation devises as used in clinical application. Internal details such as cortical and trabecular bone, brain, spinal cord, teeth, sinuses and trachea provide the most realistic clinical simulation to buate the challenging effects of complex intra- and extra-cranial anatomies. Geometric and organic target inserts provide means for comprehensive image QA, geometric machine QA and TPS QA for increased confidence in system perbance.
Dose measurements at isocenter and off isocenter bs Steev accommodates a variety of interchangeable tissue equivalent inserts suitable for small field dosimetry including: micro- and pin-point ion chambers, film, MOSFET, TLD, OSL (nanoDot?*) and 3D gel. When used in concert with the various imaging inserts, Steev provides the most comprehensive end-to-end testing and QA solution for SRS systems.
