Image-guided percutaneous lung biopsy is an essential procedure in lung cancer management, where it is integral to confirming the diagnosis and determining tumour histology. An ideal percutaneous lung biopsy also needs to have a short procedure time with accurate needle placement to minimize the inherent risk of the procedure. Since the 1970s, conventional Multi-detector CT (MDCT) has been the modality of choice in percutaneous lung biopsy. Recent research has proposed CT fluoroscopy and cone-beam CT (CBCT) as alternative methods. Virtual guidance has been developed to improve target visibility and access for these complex cases. More specifically, it plans a potential computed 3D needle path before the procedure, using the CBCT images. This 3D path can be transposed onto real time fluoroscopic images to guide the biopsy, thus potentially improves patients' safety due to more accurate needle placement.
