Abstract
Computed tomography fluoroscopy (CTF) is a technique that provides the physician immediate feedback via the reconstruction and display of CT images in real time and overcomes the classic limitations of ultrasound imaging and conventional fluoroscopy. It matches the advantages of CT quality images to be matched with the speed of fluoroscopic guidance. CTF images: (1) have a wide dynamic range for imaging air, soft tissue and bone, (2) do not superimpose anatomical structures in the same way as conventional fluoroscopy does, and (3) they provide acceptable image quality relatively unaffected by the patient’s breathing and motion (Kato et al. 1996; Froelich et al. 1998; Nickoloff et al. 2000). These characteristics allow immediate correction for the depth and direction of a needle during a percutaneous procedure. The obvious benefits of obtaining CT images in real time has made CTF a popular image guiding tool for various types of non-vascular and therapeutic interventions.
