“…Giannakou et al studied phantoms using a new frameless MRI-guided robotic system that has the advantage that, with a single catheter insertion, the biopsy needle can perform both tissue suction and ablation of the lesion using high-intensity therapeutic ultrasound in cases of localized malignant tumors [ 14 ]. This new tool is useful for diagnosis, and if a tumor is proven malignant, its size allows it to ablate the lesion in a single surgery.…”

Stereotactic brain biopsy is one of the most frequently performed brain surgeries. This review aimed to expose the latest cutting-edge and updated technologies and innovations available to neurosurgeons to safely perform stereotactic brain biopsy by minimizing the risks of complications and ensuring that the procedure is successful, leading to a histological diagnosis. We also examined methods for improving preoperative, intraoperative, and postoperative workflows. We performed a comprehensive state-of-the-art literature review. Intraoperative histology, fluorescence, and imaging techniques appear as smart tools to improve the diagnostic yield of biopsy. Constant innovations such as optical methods and augmented reality are also being made to increase patient safety. Robotics and integrated imaging techniques provide an enhanced intraoperative workflow. Patients’ management algorithms based on early discharge after biopsy optimize the patient’s personal experience and make the most efficient possible use of the available hospital resources. Many new trends are emerging, constantly improving patient care and safety, as well as surgical workflow. A parameter that must be considered is the cost-effectiveness of these devices and the possibility of using them on a daily basis. The decision to implement a new instrument in the surgical workflow should also be dependent on the number of procedures per year, the existing stereotactic equipment, and the experience of each center. Research on patients’ postbiopsy management is another mandatory approach to enhance the safety profile of stereotactic brain biopsy and patient satisfaction, as well as to reduce healthcare costs.

“…Thus, a riskvalue analysis needs to be conducted for any system deciding to add additional automated features. While the value may be high for additional features (such as continuous MRI guidance [31][32][33] ), these same features and benefits might also be provided without the additional concerns of automation (such as use of a remote, mechanical manual introducer).…”

In this paper, we highlight promising technologies in each phase of a robotic neurosurgery operation, and identify key factors affecting how quickly these technologies will mature into products in the operating room. We focus on specific technology trends in image-guided cranial and spinal procedures, including advances in imaging, machine learning, robotics, and novel interfaces. For each technology, we discuss the required effort to overcome safety or implementation challenges, as well as identifying example regulatory approved products in related fields for comparison. The goal is to provide a roadmap for clinicians as to which robotic and automation technologies are in the developmental pipeline, and which ones are likely to impact their practice sooner, rather than later.

“…Such robotic‐assisted approaches require high accuracy and precision in order to reach a target with minimal invasion and fulfil the clinical requirement. All methodologies for testing a robot's mechanical accuracy as well as the accuracy and repeatability of positioning a biopsy needle are based on comparing the intended with the actual motion step as determined using a distance‐measuring method 22,23 . Before a process can be implemented in in vivo applications, its accuracy is typically assessed in free space, also known as the intrinsic system accuracy.…”

BackgroundThe current study proposes simple methods for assessing the performance of robotic devices intended for Magnetic Resonance Imaging (MRI)‐guided needle biopsy.MethodsIn‐house made agar‐based breast phantoms containing biopsy targets served as the main tool in the evaluation process of an MRI compatible positioning device comprising a needle navigator. The motion accuracy of mechanical stages was assessed by calliper measurements. Laboratory evaluation of needle targeting included a repeatability phantom test and a laser‐based method. The accuracy and repeatability of needle targeting was also assessed by MRI.ResultsThe maximum error of linear motion for steps up to 10 mm was 0.1 mm. Needle navigation relative to the phantom and alignment with the various biopsy targets were performed successfully in both the laboratory and MRI settings. The proposed biopsy phantoms offered tissue‐like signal in MRI and good haptic feedback during needle insertion.ConclusionsThe proposed methods could be valuable in the process of validating the accuracy of MRI‐guided biopsy robotic devices in both laboratory and real environments.

MRI‐guided frameless biopsy robotic system with the inclusion of unfocused ultrasound transducer for brain cancer ablation

Abstract: A functional MRI-guided robotic system was produced which can perform frameless brain biopsy. In the future, if a tumour is proven malignant, the needle can be pulled-out and a small ultrasonic transducer can be inserted to ablate the tumour.
