Poster - Thurs Eve-21: Experience with the Velocity(TM) pre-commissioning services
Medical Physics
|May 18, 2017
Summary
Siemens Velocity™ program provided efficient commissioning data for radiation therapy. This allowed for confident beam modeling and accelerated the opening of a new clinic with advanced Image-Guided IMRT.
Area of Science:
- Medical Physics
- Radiation Oncology
- Radiotherapy Technology
Background:
- The implementation of new linear accelerators (linacs) requires precise commissioning of radiation therapy treatment beams.
- Accurate beam data modeling is crucial for effective treatment planning and patient safety.
- Siemens Velocity™ program offers factory-based commissioning data measurement to streamline this process.
Purpose of the Study:
- To evaluate the experience of the first Canadian users of the Siemens Velocity™ program.
- To assess the efficiency and quality of factory-measured commissioning data for treatment planning.
- To determine the impact of the Velocity™ program on the timeline for opening a new radiotherapy clinic.
Main Methods:
- Utilized factory-measured commissioning data from the Siemens Velocity™ program for two photon and six electron energies.
- Modeled treatment beams, including Virtual Wedge, physical wedge, and IMRT, in the treatment planning system.
- Validated and slightly modified the factory-generated beam models.
- Collected data at 100 and 110 cm Source-to-Surface Distance (SSD).
Main Results:
- The Velocity™ program provided professional and efficient data collection.
- Generated comprehensive beam models and a complete data book for photon and electron beams.
- Final beam models required only minor user-specific modifications.
- The program facilitated confident beam data and modeling, saving time for other clinic setup tasks.
Conclusions:
- The Siemens Velocity™ program proved to be a highly positive and efficient solution for linac commissioning.
- The program enabled rapid and confident implementation of treatment planning capabilities.
- Assisted in the successful and timely opening of a three-linac clinic offering Image-Guided IMRT within 4.5 months of machine delivery.

01:20Velocity Potential

In steady, incompressible flow through a long, straight pipe with a uniform cross-section, the flow in the central region (far from the pipe walls) is irrotational. This irrotational nature means that fluid particles do not rotate around their axes, and a scalar function called the velocity potential, represented by ϕ, can be used to describe their movement. In irrotational flows, the velocity field V is defined as the gradient of the velocity potential:

01:11Velocity and Acceleration in Steady and Unsteady Flow
441
In fluid mechanics, velocity and acceleration are key concepts for analyzing particle motion in both steady and unsteady flow. Consider a fluid particle moving along a pathline, where its velocity depends on its position and time. The particle's acceleration is obtained by differentiating the velocity with respect to time.
The acceleration can be generalized to any point in the flow, and expressed as components along three perpendicular directions, representing changes in velocity over...

00:51Velocity and Acceleration of a Wave
5.0K
A wave propagates through a medium with a constant speed, known as a wave velocity. It is different from the speed of the particles of the medium, which is not constant. In addition, the velocity of the medium is perpendicular to the velocity of the wave. The variable speed of the particles of the medium implies that there must be acceleration associated with it.
The velocity of the particles can be obtained by taking the partial derivative of the position equation with respect to time....

01:18Velocity of an Object

Understanding how an object moves along a path requires distinguishing between motion over a time span and motion at a precise moment. A useful example is a vehicle traveling along a straight and level path, where its position at any given time is known. The initial step in analyzing this motion is to measure how far the vehicle travels over a fixed time period. This measurement, called average velocity, is computed by dividing the total change in position by the duration over which the change...

01:13Velocity and Position by Integral Method

If acceleration as a function of time is known, then velocity and position functions can be derived using integral calculus. For constant acceleration, the integral equations refer to the first and second kinematic equations for velocity and position functions, respectively.
Consider an example to calculate the velocity and position from the acceleration function. A motorboat is traveling at a constant velocity of 5.0 m/s when it starts to decelerate to arrive at the dock. Its acceleration is...

Uniform circular motion is motion in a circle at a constant speed. Although this is the simplest case of rotational motion, it is very useful for many situations and is used to introduce rotational variables. When a particle is moving in a circle, the coordinate system is fixed and serves as a frame of reference to define the particle’s position. Its position vector from the origin of the circle to the particle sweeps out the angle θ, which increases in the counterclockwise direction...
