- W2472685954 abstract "Purpose:The purpose of this study is to develop a method to evaluate the clinical utility of a high resolution 75µ pixel MAF-CMOS image receptor compared to a 200µ flat-panel detector (FPD).Methods:A simulated procedure evaluation method was developed using an aneurysm phantom since every clinical device-deployment procedure is different and to faithfully compare the performance of two detectors in a clinical setting would require the device deployment to be stopped at different stages so that images could be acquired with both detectors. Not only is this extremely challenging to implement for a large case cohort, it also requires additional exposure and risk to the patient. To simulate a treatment procedure, a 3D printed aneurysm phantom based on patient morphology was used. An anthropomorphic head phantom was placed underneath the aneurysm phantom to simulate patient attenuation and anatomical features. An endovascular coil was deployed into the aneurysm under the guidance of both the MAF-CMOS and the FPD. To qualitatively evaluate the performance of the detectors based on images, a questionnaire containing visualization criteria was developed and a grading scale from 1 (lowest) to 10 (highest) was assigned to each question. The images from these procedures along with the questionnaire will be presented to observers to qualitatively evaluate and compare the performance of the two detectors.Results:Realistic clinical interventions were simulated using a patient-specific aneurysm phantom. Using a common set of criteria in a questionnaire to individually evaluate these images and then comparing the results for a large cohort can be an effective method to determine the significance of using the MAF-CMOS detector during clinical procedures.Conclusion:The above method can be used to effectively evaluate the clinical utility of the MAF-CMOS detector without additional risk to the patient.partial support from NIH Grant R01-EB002873 and equipment grant from Toshiba Medical Systems Corp." @default.
