Summary
Augmented reality (AR) shows potential in surgery but has limitations. This study found AR pedicle instrumentation had more breaches than fluoroscopy, highlighting areas for improvement in surgical navigation.
Area of Science:
- Neurosurgery
- Medical Technology
- Surgical Navigation
Background:
- Augmented reality (AR) adoption is growing across various fields, including medicine.
- Neurosurgical applications of AR remain largely underdeveloped and limited.
Purpose of the Study:
- To evaluate the feasibility and accuracy of AR-assisted pedicle instrumentation in a cadaver model.
- To compare AR-guided screw placement with traditional fluoroscopy-assisted methods.
Main Methods:
- Pedicle instrumentation (thoracic 1 to pelvis) was performed on cadavers using either fluoroscopy or AR.
- Available AR equipment and software were utilized for the procedure.
Main Results:
- A total of 38 screws were placed during the study.
- Fluoroscopy-assisted placement resulted in no major breaches.
- AR-assisted placement had 7 major breaches (3 medial, 4 inferior), potentially due to starting position errors.
Conclusions:
- Current AR technology has limitations for neurosurgical applications like pedicle instrumentation.
- Strategies for improving AR accuracy and successful implementation in future surgeries are discussed.

Instrument transformers, comprising voltage transformers (VTs) and current transformers (CTs), play crucial roles in power substations by providing isolated replicas of current or voltage for measurement and protection purposes. Voltage transformers reduce the primary voltage to levels suitable for relay operation and measurement, while current transformers scale down the primary current. The primary winding of a current transformer often consists of a single turn, achieved by threading the...

An electrocardiography (ECG) machine is an essential piece of medical equipment used to monitor the electrical activity of the heart. It operates by detecting small electrical changes on the skin that result from the depolarization of the heart muscle during each heartbeat. However, these signals are in the microvolt range and can be easily overwhelmed by noise or interference.

51.1K
Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

Capillary electrophoresis instrumentation typically consists of several key components. A high-voltage power supply generates the electric field necessary for the separation by connecting to an anode (the positively charged electrode) and a cathode (the negatively charged electrode) located in buffer reservoirs at each end of the capillary tube. The system includes a sample vial, a fused silica capillary tube coated with polyimide for mechanical strength through which the sample components...

1.5K
Fluorometers and spectrofluorometers are two types of instruments used for measuring molecular fluorescence. These instruments differ in how they select excitation and emission wavelengths and the type of light sources they utilize. Fluorometers use absorption interference filters to choose excitation and emission wavelengths. The excitation source in a fluorometer is typically a low-pressure mercury vapor lamp that emits intense lines distributed throughout the ultraviolet and visible regions.
