Determinants of radiation exposure during mobile cone-beam CT-guided robotic-assisted bronchoscopy.

ABSTRACT:

Background and objective

Robotic-assisted bronchoscopy (RAB) is an emerging modality to sample pulmonary lesions. Cone-beam computed tomography (CBCT) can be incorporated into RAB. We investigated the magnitude and predictors of patient and staff radiation exposure during mobile CBCT-guided shape-sensing RAB.

Methods

Patient radiation dose was estimated by cumulative dose area product (cDAP) and cumulative reference air kerma (cRAK). Staff equivalent dose was calculated based on isokerma maps and a phantom simulation. Patient, lesion and procedure-related factors associated with higher radiation doses were identified by logistic regression models.

Results

A total of 198 RAB cases were included in the analysis. The median patient cDAP and cRAK were 10.86 Gy cm²
