Electrical Systems

Electrical Systems

In electrical engineering, the analysis of networks composed of passive linear components — resistors (R), capacitors (C), and inductors (L) — is fundamental. These components are organized into circuits where the relationship between input and output can be analyzed using transfer functions. The transfer function of an RLC circuit, which relates the voltage across a capacitor to the input voltage, can be derived using Kirchhoff's laws.
To derive the transfer function, consider an RLC...

Power System Distribution

Power System Distribution

Power system distribution involves delivering electrical energy from power plants to consumers through a network of transmission and distribution systems. The process begins at power plants, where energy from coal, gas, nuclear, water, and wind is converted into electrical energy. These plants use three-phase generators, typically rated between 50 to 1300 MVA, with terminal voltages ranging from a few kV to 20 kV, depending on the size and age of the units.
The transmission system is designed...

Electro-mechanical Systems

Electro-mechanical Systems

Electromechanical systems are intricate configurations that effectively combine electrical and mechanical elements to achieve a desired outcome. Central to many of these systems is the DC motor, a device that converts electrical energy into mechanical motion, enabling various applications ranging from simple fans to complex robotic mechanisms.
A key component of the DC motor is the armature, a rotating circuit positioned within a magnetic field. As an electric current passes through the...

Control Systems: Applications

Electrical engineering plays a pivotal role in our daily lives, with control systems at the heart of many applications, from home appliances to sophisticated space shuttles. Control systems manage and regulate the behavior of devices and processes, ensuring they function safely, correctly, and efficiently.
In modern vehicles, control systems manage various functions to enhance performance and safety. The steering wheel and accelerator are primary inputs in a car's control system. The...

Control Systems

Control Systems

Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.
At the heart...

MOS Capacitor

MOS Capacitor

A Metal-Oxide-Semiconductor (MOS) capacitor is a fundamental structure used extensively in semiconductor device technology, particularly in the fabrication of integrated circuits and MOSFETs (metal-oxide-semiconductor field-effect transistors). The MOS capacitor consists of three layers: a metal gate, a dielectric oxide, and a semiconductor substrate.
The metal gate is typically made from highly conductive materials such as aluminum or polysilicon. Beneath the metal gate lies a thin layer of...

Background:

SmartArc is a VMAT planning solution integrated with Pinnacle treatment planning system.
Clinical implementation of advanced radiotherapy techniques requires thorough configuration and validation.

Purpose of the Study:

To detail the clinical experience with configuring, commissioning, and implementing SmartArc for VMAT planning.
To evaluate the integration of SmartArc with the MOSAIQ R&V system in a clinical setting.

Main Methods:

Studied key physics parameters: machine dose rate, MLC leaf speed, and leaf motion per gantry rotation.
Developed a custom tabletop in Pinnacle to enhance dose accuracy.
Verified planner dose and absolute dose using an in-house phantom, MapCheck, and an ion chamber.

Main Results:

Recommended specific machine data settings and MLC constraints (e.g., 2.25cm/s leaf speed) for optimal performance.
Identified the need to check maximum leaf motion per gantry rotation to avoid undeliverable plans.
Validated custom tabletop and achieved satisfactory dose accuracy through phantom QA.

Conclusions:

Configuration of dose rate, MLC leaf speed, and leaf motion are critical for SmartArc implementation.
Custom tabletop creation is essential for improving planning accuracy.
SmartArc implementation with MOSAIQ R&V is feasible, though Varian 21ex delivery is slow; standard commissioning procedures apply.
