Ultrasound Imaging - Science topic

We have been able to download the maui installer to the computer, however, we cannot get the .exe file to open and run.

We have tried to run it as administrator, we disabled the firewall, we restarted the computer, nothing seems to work.

Thank you!

Is there a scoring system to assess adequacy of images acquired during the eFAST (extended Focussed Abdominal Sonography in Trauma) ultrasound scanning protocol?

I wonder if anybody knows where I could find and download some sector scan ultrasound images? I need them for doing my homework.

More specifically, if I record ultrasound on a muscle when the limb is cold, would I not be able to see fascicles as well as if I record ultrasound on a muscle at normal temperature?

Any insight on how temperature affects ultrasound image quality/resolution is appreciated!

Hey all

I have made an ultrasound image, and ultimately want to extract my SNR. For this I have cut out the background noise to compare with the quality of my target. I have made a plot of the data on a greyscale. The X-axis is the brightness of the pixel (range 0-255) and the Y-axis is the number of pixels with this brightness. Everything should be attached.

But I cant seem to calculate the correct mean. I know the standart formula, but it seems to only give me the mean of the y-axis.

Thanks

I'm looking for a dataset containing ultrasound images with tools (e.g. needles or catheters) and their segmentations. I want to train a CNN to perform the segmentation

What feature analysis techniques or new approaches can be applied to analyzing cardic ultrasound images for detection of a defect.

I cannot find any ultrasound image regarding the prostate. Could anyone give me the link if you find any? It is preferred to be 3D transrectal ultrasound images, but 2D is fine

Images are required for testing and validation of a new technique.

I am looking for standard image data set for a 2D ultrasound image of the uterus; specifically for the normal uterus, septate uterus, and bicornuate uterus.

I wonder if anybody knows where I could find and download some ultrasound images? I need them for performing the despeckling algorithm.

Before displaying an ultrasound image, the machine usually performs a logarithmic compression in order to better visualise an image in terms of grayscale. In order to treat a DICOM image, is it necessary to do a logarithmic decompression for more accurate results of image analysis and processing?

I think if frequency is increased resolution increased, is it correct?

I'm doing some research on the resolution of ultrasound images, and a lot of high-resolution ultrasound images are needed. Can someone help me?

For our study, we need anatomical MRI, CT, and sonographic images of human hands in order to run statistical analysis on them.  We would prefer to not need to make a database ourselves for the study, as MRI scan time can be extremely costly. For our study, optimal database image sets would: 

Could someone point me in the right direction?, Any and all help would be greatly appreciated.  Thankyou

Twinkling artifact was introduced by Rahmouni et al. in 1996 and defined as a rapidly changing mixture of red and blue behind presumed calcifications in Doppler color flow imaging. There were suggested several plausible causes, such as the phase jitter, the object’s microoscillations, microcavitation, etc.

What are your thoughts on this? What causes the twinkling artifact to appear?

I am working on ultrasound image quality that's why i need some vital link.

I’m working on “Using Adaptive beamforming to improve quality of the ultrasound harmonic imaging”, but I have no real data and also it is necessary for me to use this data for validating my work.

I have written two articles in my study and submitted them, but they were rejected, and main reason of rejecting them was “why you just use Simulink data, and this results are not valid?”.

I wonder if anyone has a recipe for a gel phantom for using for USS training.

Anyone please suggest me some tutorials/documents where I could learn about the de-nosing technique of Ultrasound Images?

Upto now, the only open source dataset is by Kaggle in the Ultrasound Nerve Segmentation challenge. I am looking for any open source data but they must be ultrasound images.

I'm looking for a database of ultrasound videos to analyze for use in PhD research.

i am looking for ultrasound image of common carotid artery for research. for validation its parameter like IMT, LD, BP, etc. are also required.

Does anyone know where I might find an chronic kidney disease ultrasound image database?

I am interested to segment it (somehow) and get the motion information from an echo of the heart. Any comment also on this part?

Since the power CFI and the B-flow both use a wall-filter and the energy of the echo.

Please Give suggestions

Dear Friend, Can anyone know ultrasound eye image database link. Please help me.

The following ultrasound Images of long head of biceps subluxation which was missed by MRI.

I collected 4 cases having long head of biceps subluxationtion but missed by MRI. Among them I have report of MRI of one case. On case I diagnosed in 2014 was my initial case and I didn't save the report because I was not interested in this comparative study. the second patient sent me the report on whats-app but later on it was deleted due to negligence. the third one I have and the fourth one; told me by the patient and promised to send the MRI Report but unfortunately not sent yet

I Utilized and developed a comprehensive FORTRAN code to model Ultrasound propagation in layered tissue or any other domain. this code is solving full wave equations and Bio-heat equation based on FTDT algorithm for a 2-D (X-Y) and asymmetrical (R-Z) problems and consider viscosity, heat generation, attenuation, absorption and scattering. I have validated the code with several Theoretical and experimental researches. Could you please someone introduce a problem to me? I will be pleased to do collaborate projects to write papers. So please kindly email me. my email address: hojat.rezaei@gmail.com

I need to measure the marbling score of beef steer ribeye area's ultrosinc images. Media is taken with an ultrasound. I'm using image J analyzer software but it's not that handy. Can you suggest any software?

Is it effective for the detection of fatty liver (mainly for mild degree)?

We have been using IMAGO.s for the last few yrs to check for pregnancy and measure back fat depth on reindeer. The probe we have used is a 5MHz sector probe (SB 355M I believe). However, this equipment seems to break down every year. Either the batteries go dead or the probes. The equipment is only used in the latter part of the winter (January-April), and we have been told by the company that we need to turn on the equipment, discharge the battery and recharge it regularely (we do it every 1-2 months). However, this approach do not seem to help. Are there anyone out there who have suggestions for another portable, and reliable model of ultrasonography equipment, suitable to bring out in winter field conditions. I think we are giving up on ECM Imago.s.

Hi all, I am looking for someone who is familiar with the ultrasound of the aorta that could help me have a look of my ultrasound images from mouse descending aorta. I've marked the area that I am not quite sure about with a red rectangle. It seems that the area I marked is connected to the descending aorta, but I wonder this part belongs to some other tissue (e.g., atrium?). Thanks!

Dear all,

Do ultrasound images have impulse noise or is it just speckle noise?

Thanks,

How many different approaches are possible for segmentation and which one do you  recommend for Echocardiogram?

am working on US images for cardio vascular diseases and need to segment those images by classification, would that be possible

I am research about the texture analysis of liver by ultrasound image. 

I am working on binary segmentation of ultrasound images, i.e. from a noisy (mostly speckle noise, I would say) ultrasound image I want to obtain a black and white image. 

For finding the global pixel intensity threshold I'm using Otsu's method, which works reasonably well. 

Now my question is, what image (pre-) processing steps would one perform on an ultrasound image prior to finding the intensity threshold via, e.g. Otsu's method. 

Is Gaussian blurring, median filtering etc. a good idea or does it destroy the pixel intensity histogram? What is the common work flow or image processing pipeline prior to image segmentation? 

Thanks a lot for your insights (I'm new to image processing)

Hi all, for a medical imaging project, we are looking for databases of ultrasound images, particularly for regional anaesthesia (nerve blocks). Any idea?

I believe a normal ultrasound scan only delays the diagnosis and increases the agony of patients to  end up in reccurent chronic appendicitis

simple inflamed appendicitis has limitation in diagnosis using simple and cheap ultrasound machines. Any other way from new modern ultrasounds apart from clinical assessment and costly CT and MRI..

I need information about TUI - Tomographic Ultrasound Imaging. How is possible to obtain these images? I'm not radiologist, I'm 3D modelling researcher and I need these images datasets for reconstruct 3D model for 3D Printing.

Is there a dataset of this TUI images available for download online? Thanks

Dear all,

Hi,

Does anybody knows segmentation ground truth  of Breast Ultrasound images

Thank you in advance.

Iam very interested in join this group.

More often the categorization of echogenicity of organs on ultrasound image is done subjectively and this leads to a high rate of inter observer variability and misdiagnosis in some instances.

A Mathematical model approach to come up with a software that can subjective categorize echogenicity of organs is a major objective of this study can any one outhere help us out on this?

I have time dependent results from time = 0 to time = 7.0e-5 second with the time step of 5.0e-8. Now I wan to converts all these results in to frequency domain using time to frequency FFT study. I have no idea on how to use this and how to plot frequency spectrum. Any kind of suggestions and help would be appreciated. Thank you

Is FK or Stolt Migration still a preserve amplitude?

Hi all,

If I form an array of individual point acoustic sources of same frequency and same output pressure with equal spacing between each other, how will the total pressure from the array depend on the number of individual elements if all the elements are triggered together? Is it a linear relation? The individual point sources will be placed close proximity to each other and all the sources will be triggered at the same instant so that the phase difference can be avoided.

Please help me if anyone has an expertise in this area.

Thanks in advance,

Jose

Or, are there any JPG made directly from dicom images?

How can we measure regurgitant blood flow using ultrasound images. Can we measure it by using images for a cycle (systole to diastole).

At a certain transducer power level the maximum intensity as well as the average intensity in a volume of interest drop rapidly (instead of in a linear manner, as I would have expected). I wondered whether this is due to some kind of rescaling in 3D-US software, but couldn't find any information on that.

Image below shows the same effect observed on a Philips SONOS 7500 3DUS. 

I am working with the following setup: Ultrasonix SonixTablet, running 'Porta SDK 6.07' on it, 4DL14-5/38 linear 4D transducer. Checked the manual for answers. I am taking pictures of metallic surgery tools in soft tissue, such as ex vivo pig hearts.

I'd be happy about any information(paper, book,..) related to that topic.

Thank you for your help

I'm testing different mathematical parameters of ultrasound images of mammary tumors in bitches that may help in determining if a tumor is malignant or benign. None of the parameters on their own are suitable, although the differences between the types of tumors are statistically significant. I am trying to determine if a cumulus of more of these parameters may be a better differentiation factor.

What can one use to validate follicle detection algorithm in ultrasound images of the ovary

In elderly patients after CABG a high diaphragm may be related to paralysis but eventration is in DD. It is hard to evaluate them by fluoroscopy and bedside sonography is the only available method in most of them.

I wonder if anybody knows where I could find and download some ultrasound images? I need them for performing an segmentation algorithm.

I've read the abstract. How do you explain that US is less sensitive but more specific than MRI in local staging of rectal cancer? I agree in full about the need of specific training (this rule is always true!), although the differences in MRI performances seem less understandable.

Why does ultrasound Images having Low Contrast

This observation has been used a lot in thermal strain imaging but this phenomenal seems lack fundamental/molecular-level explanations? Thanks.

The procedures involved.

I am trying to generate shear waves of significant amplitude and penetration depth using single element transducer rather than using phased array probe as proposed by the SSI and ARFI-shear wave techniques.  

If there is any specific transducer, please suggest me or if there is a chance of using Therapeutic transducer ?

I am looking to network with researchers who are involved, researching, or interested in medical image segmentation.

I am showcasing an exceptional example of arterial wall segmentation from one of our publications below. We have successfully used this method for studying arterial wall mechanics (stiffness, distension, etc..) in humans and mice, for studying the flow-mediated dilation of the brachial artery, and for tracking plaque specimens throughout ultrasound image sequences.

I am not sure if it may be useful to you too, but I suspect it can be useful in a variety of areas.

Attached is an ultrasound scan of the carotid artery corrupted by noise, and a corresponding file demonstrating the successful tracking of the arterial walls.

I am not sure if there are other methods available that can successfully segment image sequences with such substantial amounts of noise; but I suspect not many are available (if any at all).
