Relative Motion Analysis using Rotating Axes

Relative Motion Analysis using Rotating Axes

Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame.
However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it instrumental in...

Curvilinear Motion: Rectangular Components

Curvilinear motion characterizes the movement of a particle or object along a curved path, notably evident when envisioning a car navigating a winding road. If the car starts at point A, its position vector is established within a fixed frame of reference, where the ratio of the position vector to its magnitude signifies the unit vector pointing in the position vector's direction.
As the car advances, its position evolves over time. Quantifying the car's velocity involves computing the time...

Absolute Motion Analysis- General Plane Motion

Absolute Motion Analysis- General Plane Motion

Visualize a drone, with its propellers spinning rapidly, hovering mid-air. The fascinating movements and operations of this drone can be comprehended by applying the principle of general plane motion.
As the drone's propellers rotate, an upward force is generated that counteracts the force of gravity, enabling the drone to lift off from the ground. This initial movement of the drone is along a straight path, representing a form of translational motion. In this phase, every point on the drone...

Relative Motion Analysis using Rotating Axes-Problem Solving

Relative Motion Analysis using Rotating Axes-Problem Solving

Consider a crane whose telescopic boom rotates with an angular velocity of 0.04 rad/s and angular acceleration of 0.02 rad/s2. Along with the rotation, the boom also extends linearly with a uniform speed of 5 m/s. The extension of the boom is measured at point D, which is measured with respect to the fixed point C on the other end of the boom. For the given instant, the distance between points C and D is 60 meters.
Here, in order to determine the magnitude of velocity and acceleration for point...

Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Background:

Motion artifacts significantly degrade the quality of Magnetic Resonance Imaging (MRI) scans.
Accurate motion detection and correction are crucial for reliable diagnostic interpretation and quantitative analysis in MRI.

Purpose of the Study:

To develop and validate a novel real-time strategy for detecting and correcting full three-dimensional (3D) rigid-body motion in two-dimensional (2D) multislice MRI.
To enhance the robustness and applicability of motion correction techniques in dynamic MRI scenarios.

Main Methods:

Utilized two through-plane navigator echoes per slice to reconstruct orthogonal projection images within each repetition time.
Employed a regional image correlation measure for robust detection of in-plane rotation and translation, resilient to orthogonal rotation and noise.
Incorporated an additional orbital navigator for real-time detection of in-plane rotation and rejection of intra-repetition time motion.

Main Results:

Demonstrated the efficacy of the proposed real-time motion correction strategy through successful in vivo brain studies.
Validated the method's ability to accurately track and compensate for complex 3D head movements during MRI acquisition.

Conclusions:

The developed real-time 3D motion correction method is effective and requires no additional hardware.
This approach eliminates the need for extra 3D radiofrequency excitation, simplifying implementation and preserving scan efficiency.
