Medical imaging Definition and 22 Threads

Startups in avant-garde technologies.

Here we review the mathematics that goes into CT scanners and the inversion of the Radon transform. The approach given here uses the Moore-Penrose pseudo inverse to invert a tall and skinny matrix. We can get a nice representation of the pseudo inverse by using the singular value decomposition (SVD)

Good morning, I would like to know if its possible to do my Master degree in any field related to space and astronomy, actually I graduated with bachelor of applied science (Medical Imaging). I deal with x-ray and imaging machines. My courses were somewhere between biology, x-ray (radiation)...

Homework Statement Discuss the main advantage and disadvantage brought about by a reflection coefficient being very small, and hence highlight the attributes that an ultrasound scanner must have to fully exploit very small boundary reflection. Homework EquationsThe Attempt at a Solution I am...

Hi, I am doing research in content based image medical image retrieval using radon barcodes. I have replicated an approach found in this paper 277011226_Barcode_Annotations_for_Medical_Image_Retrieval_A_Preliminary_Investigation. I have tried to make some improvements to this process regarding...

< Mentor Note -- thread moved to HH from the technical physics forums, so no HH Template is shown >[/color] Hi guys, I'm an IT student 'and lill favour in my masters research work so please help me to have valid answers for following questions ASAP. 1. Do patient specific MRI contains the...

Suppose I want to learn about MRI. Some of the introductory treatments I have seen aimed at engineers or imaging professionals may not assume much more than sophomore level physics competency. I know some advanced QM and statistical physics so I am wondering about the existence or value of a...

First of all, this is my first post here, so hello everyone! Great to be a part of this online community! Secondly, to get to the point of the thread, I have recently applied and have been accepted to two master's programs in Germany, specifically Biomedical Engineering and Nuclear Applications...

Hello, I am wondering if the boards can reccomend any topics of medical imaging in healthcare. I have to make a presentation on the topic and write a paper. The paper must only be sourced from peer reviewed articles or government statistics. So it should be realitvely well known. I believe...

I have a PhD in medical physics from the MD Anderson CAMPEP program and I even took ABR step 1 (just prior to the cut off for residency requirements). Are there any imaging physicists here? Woudl really like to get your feedback on the current outlook for diagphys careers. I have not been having...

Hi everyone. I'm just looking for an online description of the nuclear magnetic resonance machine, with explanations of all components, and their physical principles...anyone can help me? Giving me any link to a website talking about it? In addiction, could be this be a valid topic for a...

I was recently taught that the probability of the photoelectric effect occurring was proportional to Z^3 and E^-3 (where Z is the atomic number, and E is the energy of the photon). My understanding is that the photon's energy must be close to the binding energy of the inner electron to be...

hi, i have to prepare a presentation about rf imaging. But i didn't found any medical imaging system using rf. Is there anyone know commercial rf medical imaging system, please help me.

Forum, I am an engineering student from Melbourne Australia and I have a simple question related to a literature research project I'm currently undertaking, hopefully someone can help me out. Which engineering or safety standards would a design for a CT or fluoroscopy system, more...

So I'm an EE undergrad student and the design of medical imaging devices is one area I'm interested in. I often hear that's more appropriate for a BME major. However, designing medial imaging devices undoubtedly involves a lot of knowledge in electronics design, signal processing...

I'm graduating this year with a master in nuclear physics. In my bachelors I did a minor in medical radiation physics. This way I was introduced to medical imaging and I decided to take elective courses from the postgraduate advanced medical imaging. If I hadn't chosen my thesistopic then, I...

By this time next year I will have earned myself a masters degree in nuclear physics. My plan up till now was to do a second master in nuclear engineering, but the current climate in Europe and here in Belgium have put me off of that idea. This year I followed a course with the engineers on...

Hi, I came across this forum and decided to post this question. I am in my second year of undergraduate studies. My goal is to have a career in Medical Biophysics or Radiology, more specifically working in Medical Imaging. I was wondering how much physics is needed in general? I am currently...

Hi Im comparing PET scans and MRI scans and I've noticed that MRI s spatial resolution is 0.3-1mm while PET scans have a spatial resolution much larger, around 5-7mm. I was just wondering how these figures are calculated. I've looked up some formulae and all I could find was wikipedia...

I am currently in my last year of a B.S. Physics degree. I have an emphasis in medical physics and have spent the past year interning at the local cancer center's radiation oncology department. I love the field, but interning has made me realize that the patient interaction is not for me. I'd...

Hoping to go into Medical Imaging in grad school. I have a coupleish years left of my undergrad in physics. My school doesn't offer any medical imaging classes was wondering if anyone teaches or has taken a course and could recommend a text for a little self study. Thanks.

Hey people, I'm currently finished junior, and now looking for grad schools in medbio physics (preferably medical imaging, i.e. MR, X-ray). Can anyone suggest the best schools for this to apply? Thanks!
