Laser-guided computed tomography puncture system: simulation experiments using artificial phantom lesions and preliminary clinical experience

Abstract

This system has the potential to accomplish the CT-guided puncture procedure safely and accurately.

Computer tomography guided lung biopsy using interactive breath-hold control: a randomized study

“…Unfortunately, high radiation exposure to both the patient and the operator argues against this method as a routine. An alternative, which decreases the risk of radiation, is to perform the lung biopsy using stepwise CT with laser-guided puncture (12,13), which, however, has the disadvantage of depriving the operator of real-time guided biopsy. In this context, we decided to investigate the use of IBC in connection with stepwise CT-guided lung biopsy with laser-guided puncture.…”

Radiation dose and quickness of needle CT-interventions using a laser navigation system (LNS) compared with conventional method

“…In recent years, numerous devices for facilitating computed tomography (CT)-guided interventions have been developed [1][2][3][4][5], such as robotic-assisted techniques [6], and laser marker systems [4]. Those devices have the potential of accurate and safe performance of the puncture [1,3] in addition to reduction of the radiation exposure during the intervention [4]. The improved accuracy of intervention is specially needed in case of targeting small lesions [4].…”

“…The improved accuracy of intervention is specially needed in case of targeting small lesions [4]. In the context of other puncture devices for CT-guided interventions, most laser-guided systems have the advantage of not obstructing the puncture site as much as other devices of avoiding direct contact of the device with the needle [1].…”

Intervention Planning Using a Laser Navigation System for CT-Guided Interventions: A Phantom and Patient Study

“…Numerous devices to facilitate computed tomography (CT)-guided interventions have been developed recently ( 1 2 3 4 5 6 7 ) to allow for optimal needle placement at an exact angle ( 6 8 ). Compared to other imaging methods for punctures, such as magnetic resonance imaging (MRI) or ultrasound, CT offers fast image acquisition, widespread availability, and high resolution accurate image quality.…”

“…Compared to other imaging methods for punctures, such as magnetic resonance imaging (MRI) or ultrasound, CT offers fast image acquisition, widespread availability, and high resolution accurate image quality. CT-guided punctures can be facilitated using CT-fluoroscopy, robotic devices, mounted systems, hand-held devices, systems that require attachment to the patient's skin, or laser devices ( 1 2 3 4 5 6 7 ).…”
