Proton density fat fraction of the spinal column
An MRI cadaver study
Background: The increased popularity of minimally invasive spinal surgery calls for a revision of guidance techniques to prevent injuries of nearby neural and vascular structures. Lipid content has previously been proposed as a distinguishing criterion for different bone tissues

Optical Methods for Brain Tumor Detection
A Systematic Review
Background: In brain tumor surgery, maximal tumor resection is typically desired. This is complicated by infiltrative tumor cells which cannot be visually distinguished from healthy brain tissue. Optical methods are an emerging field that can potentially revolutionize brain tumor

Design of a sideways-looking fiber-optic probe to advance spine surgery
Our research highlights the potential of Diffuse Reflectance Spectroscopy (DRS) in detecting cortical breaches during pedicle screw placement. We propose a sideways-looking fiber-optic probe, integrating diffuse light emission with both forward and sideways light collection. Expe
...
Diffuse Reflectance Spectroscopy (DRS) can provide tissue feedback for pedicle screw placement in spine surgery, yet the integration of fiber optics into the tip of the pedicle probe, a device used to pierce through bone, is challenging, since the optical probing depth and signal
...
Accuracy in spinal fusion varies greatly depending on the experience of the physician. Real-time tissue feedback with diffuse reflectance spectroscopy has been shown to provide cortical breach detection using a conventional probe with two parallel fibers. In this study, Monte Car

Protruding Fiber Configurations using DRS in Bone Awls
Potential low-resource guidance technology for pedicle screw placement
In recent decades, spinal fixation surgery has become a routine surgery. The procedure stiffens the spine using a combination of pedicle screws and rods and eliminate any relative motion between adjacent vertebrae. The accurate placement of the pedicle screws is crucial as inaccu
...
Design of a combined optical and structural bone phantom
Concept validation and design tool
Introduction: Although being the most advanced spinal stabilization method, pedicle screw fixation has an increased number of complications compared to other surgical procedures, due to the complex spinal anatomy, large inter-patient anatomical variability, and the highly vulnera
...
The Design of an Optics-Based Bone Quality Sensing Device
A Sensing Device for Assistance in Pedicle Screw Placement - A Proof of Concept
Treatment methods for spinal disorders involving spinal fusion surgery often entail lengthy and expensive procedures, with a risk of damage to surrounding tissues. Breach detection tools aid in precise pedicle screw placement, thereby reducing the risk of complications or misalig
...
The spine is an intricate and crucial part of the human body. Unfortunately, spinal conditions such as scoliosis and trauma can cause instability and deformity to the spine. Patients can experience discomfort and pain. Spinal fusion surgery is used to repair and correct severe ca
