Summary
New software enhances conventional computer-assisted surgery by enabling intra-operative image updates. This virtual tool visualizes surgical progress and removed tissue, particularly useful around bony structures.
Area of Science:
- Medical Imaging
- Surgical Navigation
- Computer-Assisted Surgery
Background:
- Conventional navigation systems lack intra-operative image modification capabilities.
- Surgical progress visualization requires new imaging scans, delaying feedback.
Purpose of the Study:
- To evaluate new software for intra-operative image updates in computer-assisted surgery.
- To assess the utility of virtual image modification during surgical procedures.
Main Methods:
- A feasibility study tested new software integrated with conventional navigation.
- The software allows tracing and viewing of surgically removed tissue volumes within diagnostic images.
Main Results:
- The software provides accurate virtual image updates of surgical progress.
- Surgeons can visualize the amount of tissue removed during procedures.
- Effectiveness is high around bony structures.
Conclusions:
- The software is a valuable addition to computer-assisted surgery in specific scenarios.
- It offers improved visualization of surgical progress and tissue removal.
- Limited suitability exists for procedures involving mobile structures or significant soft tissue shifts.

803
Arrhythmias are disturbances in the heart's rhythm that lead to abnormal heartbeats. These irregularities can originate from different parts of the heart and are classified based on their origin and nature.
Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...

1.9K
The operational amplifier, often referred to as an op-amp, is a multifaceted building block of a circuit. This electronic component functions like a voltage-controlled voltage source and can also be used to create a voltage- or current-controlled current source. The design of an operational amplifier enables it to execute mathematical operations when external components like resistors and capacitors are linked to its terminals. An op-amp has the capacity to sum signals, amplify a signal,...

01:12What is an Experiment?
17.6K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

01:20Vector Operations
2.2K
Vectors are physical quantities that have both magnitude and direction. The vector operations include addition, subtraction, and scalar multiplication.
A vector multiplied by a scalar value is called scalar multiplication. The result obtained is a new vector with a different magnitude. If the scalar is positive, the direction of the vector remains the same, but if it is negative, the direction of the vector is reversed. For example, the product of the mass and velocity yields the momentum.

2.8K
Operant conditioning, a key concept in behavioral psychology, involves using reinforcement and punishment to alter the likelihood of a behavior being repeated. B.F. introduced this type of conditioning. Skinner focused on voluntary behaviors and the consequences that follow them, influencing whether these behaviors will be strengthened or diminished.
Reinforcement in operant conditioning can be positive or negative, both of which serve to increase the likelihood of a behavior. Positive...
