Ct to body divergence
WebCT-to-body divergence was measured using pre-procedural CT images and intraprocedural CBCT images taken immediately after intubation, aligned on the basis of the central airways. The distance between lesion centers in the X , Y , and Z directions was measured as a vector and actual CT-to-body divergence was calculated as d =√( x 2 + … Webuses tomography to compensate for CT-to-body divergence, prior to the biopsy. For these reasons, we are using the cleared Auris Surgical Monarch Platform (K173760), and Covidien superDimension™ Navigation System (K173244) as the predicate and reference devices, respectively Performance Data

WebCT-to-body divergence is the discrepancy between the static pre-op CT scan and the dynamic breathing lung. Regardless of navigation technology, this can affect the … WebJun 26, 2024 · EMN was thus introduced to guide navigation to these peripheral pulmonary lesions (PPLs) but lacked direct visualization of the airways. The use of EMN has been combined with r-EBUS to increase diagnostic yield but continues to be limited by respiratory motion and CT-to-body divergence.
WebCT to body divergence is thought to be a significant deterrent for successful navigation to target lesions in ENB and RAB.13 A myriad of factors contributes to CT to body divergence. Variations in lung volumes before versus during the procedure may be one of the most notable contributors. Lung volumes on the preprocedure chest CT obtained at ... WebIon’s shape-sensing technology indicated that the system believed that the proximal edge of the lesion was still 10mm further out, equating to an approximate 20mm (2cm) of CT-to …
WebAug 18, 2024 · Factors that affect the diagnostic yield of ENB guided biopsy are CT scan to body divergence (CTBD) and the absence of continuous imaging during tissue sampling. CTBD refers to the difference in target lesion location on the preprocedural CT scan used for virtual mapping of the pathway to the lesion compared to the actual lesion location in the
WebDec 30, 2024 · The concept that the true location of a PPL is not consistent with the navigated target is known as “CT-body divergence.” This likely occurs due to differences in lung volume at the time that the planning CT …
