Daniel Qu and Princesa VanBuren-Hansen developed a mathematical model to compensate for inhomogeneous magnetic fields in portable MRI machines. They used a novel radial sweep imaging technique combined with an additional frequency sweep term in the Powell magnetization equation. Testing showed images produced from their model matched simulations, proving an inhomogeneous field can produce satisfactory images. This demonstrates the feasibility of a portable MRI for use in locations where large, expensive machines are not practical.

The document describes a new regression model developed to estimate global solar radiation using artificial neural networks. The model was developed based on the Angstrom-Prescott model and used only latitude and altitude as inputs to estimate monthly average daily global solar radiation. The neural network model with 10 hidden neurons was trained on data from 4 locations in North India. The model estimated regression coefficients a ranging from 0.209 to 0.222 and b ranging from 0.253 to 0.407. Validation tests showed good agreement with actual solar radiation values.

Change detection in Hyperspectral data.ppt
The document discusses adapting the IR-MAD change detection method for use with hyperspectral data. It proposes using principal component analysis (PCA) for feature reduction before applying IR-MAD to address the high dimensionality of hyperspectral data. An initial change mask is also used to eliminate strong changes and isolate no-change pixels for analysis. Experiments on Landsat and hyperspectral data demonstrate the effectiveness of the approaches. Current work involves using Markov random fields to incorporate spatial information and generate a final change classification map.

This document discusses using quantitative MRI (qMRI) to assure safety in radiation treatments for cancer. It notes that about half of cancer cases in Flanders are treated with radiation therapy using various techniques like IMRT. However, routine surveys show about 1/3 of radiation therapy centers fail target criteria. qMRI allows 3D dosimetry that mimics patient treatments, with gel phantoms undergoing the same planning and irradiation steps. This yields dose maps with R2 relaxation rate measurements correlated to absorbed dose. Current projects aim to improve gel dosimeters, accuracy, and clinical validation through multicenter studies to safely verify radiation therapy plans with qMRI.

Magnetic resonance imaging (mri) asit meher ppt
The document provides an overview of MRI (magnetic resonance imaging). It discusses how MRI works by using strong magnetic fields and radio waves to produce detailed images of the inside of the body. It describes some of the key components of an MRI machine, including the superconducting magnet which generates the magnetic field, gradient coils which produce variations in the field, and RF coils which transmit/receive radio signals. It also touches on how the magnets need to be cooled to operate in a superconducting state to maintain the large magnetic fields required for MRI.

Magnetic resonance imaging (MRI) uses powerful magnets and radio waves to produce detailed three-dimensional images of the inside of the body. It is often used for disease detection and diagnosis. MRI works by aligning hydrogen protons in the body using magnetism and radio waves, and uses different magnetic fields to produce T1-weighted and T2-weighted images that show tissue types with different densities. MRI is safer than CT scans as it does not use ionizing radiation. However, it employs strong magnetic fields and some people may experience claustrophobia during long scans inside the MRI machine.
International Journal of Image Processing (IJIP) Volume (1) Issue (1)
This document discusses a new method for enhancing magnetic resonance images (MRI) using multiscale retinex (MSR) to correct image inhomogeneities and enhance contrast. MSR employs single-scale retinex with different weightings to address non-uniform grayscale, improve contrast, correct inhomogeneity, and clarify deep brain structures in MRIs captured using surface coils. The performance is evaluated using peak signal-to-noise ratio and contrast-to-noise ratio on phantom and animal images, and is shown to outperform other methods like histogram equalization and wavelet-based algorithms. The retinex algorithm is thus a valuable method for MRI image processing.

MRI uses powerful magnets and radio waves to generate detailed images of the inside of the body. It has several key components, including a superconducting magnet that provides a strong magnetic field, gradient coils that vary the field to provide positional information, and RF coils that transmit pulses to excite protons and receive their signals. To function properly, the superconducting magnet must be cooled to very low temperatures using liquid helium, and advanced cooling systems like laser cooling are being developed and researched. The computer system digitizes the received signals and applies transformations to construct images that can reveal soft tissue structures and abnormalities.

Magnetic resonance imaging (MRI) is a non-invasive medical imaging technique that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body. It employs radiofrequency radiation in the presence of magnetic fields to map the internal structure and function of the body. MRI works by aligning water molecules in the body with the magnetic field, applying radio signals to produce signals from tissues, and using gradients to spatially encode the signals to construct cross-sectional images of the body.

Correction of Inhomogeneous MR Images Using Multiscale Retinex
A new method for enhancing the contrast of magnetic resonance images (MRI) by retinex algorithm is proposed. It can correct the blurrings in deep anatomical structures and inhomogeneity of MRI. Multiscale retinex (MSR) employed SSR with different weightings to correct inhomogeneities and enhance the contrast of MR images. The method was assessed by applying it to phantom and animal images acquired on MRI scanner systems. Its performance was also compared with other methods based on two indices: (1) the peak signal-to-noise ratio (PSNR) and (2) the contrast-to-noise ratio (CNR). Two indices, including PSNR and CNR, were used to evaluate the performance of correction of inhomogeneity in MR images. The PSNR/CNR of a phantom and animal images were 11.8648 dB/2.0922 and 11.7580 dB/2.1157, respectively, which were higher or very close to the results of wavelet algorithm. The retinex algorithm successfully corrected a nonuniform grayscale, enhanced contrast, corrected inhomogeneity, and clarified the deep brain structures of MR images captured by surface coils and outperformed histogram equalization, local histogram equalization, and a waveletbased algorithm, and hence may be a valuable method in MR image processing.

Panchromatic and Multispectral Remote Sensing Image Fusion Using Machine Lear...DR.P.S.JAGADEESH KUMAR
This document discusses machine learning techniques for fusing panchromatic and multispectral remote sensing images to classify rural and farming regions. It provides background on panchromatic and multispectral imaging systems and describes common fusion algorithms like IHS transform and PCA. The authors applied machine learning methods to fuse high resolution panchromatic and low resolution multispectral images. Qualitative and quantitative assessment showed the machine learning approach provided better performance than other fusion algorithms in enhancing image quality and enabling effective classification of rural and farming areas.Magnetic Field Line Tangling and Topological Entropy
Mixing of two-dimensional flows or three-dimensional magnetic fields is quantified using the finite time topological entropy FTTE. Similar to the finite time Lyapunov exponent it quantifies the amount of mixing of the fluid or chaotic dynamics in the system. Here we present an efficient method on how to compute the FTTE for periodic magnetic fields, like in Tokamaks, or for time periodic two-dimensional flows. Our method is both precise and highly time efficient. To show case the method we apply it to such cases that describe tangled or twisted magnetic fields.
Principle of Ultrasound Imaging
This document summarizes a presentation given by Kevin Parker on rapid advances in medical ultrasound. It discusses how ultrasound technology is becoming cheaper, faster, and better through advances like Moore's law that have allowed for the miniaturization of ultrasound components. It describes new portable ultrasound systems and the development of nonlinear imaging techniques that have improved image quality. The document also discusses emerging techniques like elasticity imaging that use ultrasound to assess tissue stiffness and detect tumors, as well as potential new applications in drug delivery guided by ultrasound.
Corner Detection Using Mutual Information
This work presents a new method of corner detection based on mutual information and invariant to image rotation. The use of mutual information, which is a universal similarity measure, has the advantage of avoiding the derivation which amplifies the effect of noise at high frequencies. In the context of our work, we use mutual information normalized by entropy. The tests are performed on grayscale images.

This document summarizes a research paper that studied the application of compressed sensing techniques to magnetic resonance imaging (MRI). It conducted simulations in MATLAB to show how sparsity of MRI signals can be exploited to accurately reconstruct images from far fewer measurements. The simulations used two MRI knee images and compared reconstruction with different sampling methods and parameters. Results demonstrated that compressed sensing enables accurate reconstruction from highly undersampled data, requiring around 4-5 times fewer measurements than the signal sparsity. This reduction in measurements can significantly decrease MRI scan times while maintaining image quality.

Among the imaging techniques, magnetic resonance imaging (MRI) is a non-contact and a non-invasive technique to obtain images of the objects rich in water content and provides an excellent tool to study variation of contrast among the soft issues. It often utilizes a linear magnetic field gradient to obtain an image that combines the visualization of molecular structure and dynamics. It measures the characteristics of hydrogen nuclei of water and nuclei with similar chemical shifts, modified by chemical environment across the object. In the present work, MRI of fresh tomatoes has been recorded using Terranova-MRI for qualitative analysis. The technique is effective, powerful and reliable as an investigative tool in the quality analysis and diagnosis of infections in fruits and vegetables.

The document proposes a new statistical technique for estimating spin-lattice relaxation time, pseudodensity, and phase parameters from complex-valued magnetic resonance images. It uses a nonlinear least squares estimator to retrieve the unknown parameters directly from the complex images, unlike conventional models. Simulations show the estimator is unbiased and rapidly converges. The approach has two advantages: it exploits both real and imaginary data for a more accurate estimation, and least squares estimation has lower computational cost than maximum likelihood estimation.

This document describes a method for systematically selecting technique factors for pediatric CT scans based on achieving similar image noise levels to adult scans. The method uses an exponential attenuation model and effective linear attenuation coefficients derived from phantom measurements to determine the necessary mAs for pediatric scans given the adult mAs and the pediatric patient's equivalent diameter. Phantom studies were conducted to validate that the method produces similar noise levels across different tube voltages and beam filtrations for various pediatric age groups compared to adults.
NIR imaging
This document describes research on using near-infrared optical imaging techniques for 3D biological tissue imaging. It discusses diffuse optical tomography (DOT) and fluorescence DOT (F-DOT). For DOT, it covers the photon diffusion equation, forward and inverse models, and finite element method implementation. For F-DOT, it discusses the fluorescence transport equations and parallel inversion schemes. Simulation results using MATLAB and NIRFAST show reconstructed optical property maps and fluorescence distributions in 2D and 3D geometries. Future work aims to further develop 3D imaging software for interfacing with DOT instrumentation.

Let’s talk about powerful conversations! We all know how to lead a constructive conversation, right? Then why is it so difficult to have those conversations with people at work, especially those in powerful positions that show resistance to change?
Learning to control and direct conversations takes understanding and practice.
We can combine our innate empathy with our analytical skills to gain a deeper understanding of complex situations at work. Join this session to learn how to prepare for difficult conversations and how to improve our agile conversations in order to be more influential without power. We will use Dave Gray’s Empathy Mapping, Argyris’ Ladder of Inference and The Four Rs from Agile Conversations (Squirrel and Fredrick).
In the session you will experience how preparing and reflecting on your conversation can help you be more influential at work. You will learn how to communicate more effectively with the people needed to achieve positive change. You will leave with a self-revised version of a difficult conversation and a practical model to use when you get back to work.
Come learn more on how to become a real influencer!

Why Psychological Safety Matters for Software Teams - ACE 2024 - Ben Linders.pdf
Psychological safety in teams is important; team members must feel safe and able to communicate and collaborate effectively to deliver value. It’s also necessary to build long-lasting teams since things will happen and relationships will be strained.
But, how safe is a team? How can we determine if there are any factors that make the team unsafe or have an impact on the team’s culture?
In this mini-workshop, we’ll play games for psychological safety and team culture utilizing a deck of coaching cards, The Psychological Safety Cards. We will learn how to use gamification to gain a better understanding of what’s going on in teams. Individuals share what they have learned from working in teams, what has impacted the team’s safety and culture, and what has led to positive change.
Different game formats will be played in groups in parallel. Examples are an ice-breaker to get people talking about psychological safety, a constellation where people take positions about aspects of psychological safety in their team or organization, and collaborative card games where people work together to create an environment that fosters psychological safety.

SciMent D Final Presentation
- 1. Science Fair Project Development of a Portable MRI Daniel Qu Princesa VanBuren-Hansen Wayzata High School
- 2. Statement of the Problem In MRI, is it possible to create a mathematical model that will work with a novel inhomogeneous magnetic field as opposed to a traditional homogeneous field?
- 3. Project Overview In traditional MRIs, a large magnet provides a very homogenous magnetic field, which is not the case in a smaller one. In order to make a portable MRI machine, one must deal with the inhomogeneity of the primary magnetic field. This project focuses on the derivation of mathematical solutions of an encoding technique that can be applied to an inhomogeneous magnetic field, proving the feasibility of a portable MRI.
- 4. Research • A novel radial sweep imaging technique is used during imaging • A new mathematical equation compensates for the inhomogeneous field • Combined, these two changes allow us to work with the inhomogeneous field and produce satisfactory images • This a proof of concept for a portable MRI, which has many medicinal applications
- 5. Hypothesis A radial imaging technique combined with an additional frequency sweep term in the Powell magnetization equation will help compensate for the inhomogeneous magnetic field and thus prove the feasibility of a portable MRI
- 7. Results The analytic image on the right panel shown in Figure 1 is the image predicted by the derived equation in this study. The left is the imaging of a circular object suspended in water. We see that the analytical solution image is almost identical to the simulation. This confirms that the new inhomogeneous field can be worked with and gives similar results to traditional MRI. Image obtained from CMRR, University of Minnesota under Dr. Garwood
- 8. Conclusion The previous image is proof that a portable MRI will work. The inhomogeneous magnetic field can be worked with to produce satisfactory images. This has medicinal application to third-world countries, war zones, and other clinics where expensive traditional MRI machines may not be feasible.
