QUESTION
so I'd like to simulate CT images from ultrasound images using GAN and I am currently working on the data preparation.
By nature of the ultrasound these images are stored in a cone shaped kind of form:
But what I want to have is the image in the following form:
I belief it is easier to simulate the CT image that way.
I am using simple ITK. I guess this should be a common transformation. Is there maybe a filter from sITK that I am not aware of? Or is there an other simple way to do this transformation?

Answered 2021-Jan-28 at 17:03The homography idea didn't work so this won't serve as an answer, but hopefully some of this is still helpful.
I basically targeted six keypoints and tried to rectify them. However, the homography didn't handle the cylindrical curve at the top and bottom.

I read a multi-frame DICOM file with pydicom, after that I write it into a new file. However when I open the DICOM file, the image has an offset/shift.

Answered 2021-Apr-27 at 23:35Encapsulation of Pixel Data (both single and multi-framed) is only required for compressed transfer syntaxes, such as JPEG or RLE Lossless. If you have an uncompressed syntax such as Explicit VR Little Endian then no encapsulation is necessary:
QUESTION
I have a basic GUI that begins with a main menu of sorts. I have successfully set a background image to that menu and it also scales when I change the dimension of the GUI window. However when I try to define some top-level windows that are opened by the sub-menu items the background image does not appear (not to mention scale). Not sure what I'm doing wrong but I'm attaching the code I wrote along with the images of the basic GUI.

QUESTION
I'm brand new to DSP and I'm experimenting with GFSK modulation to eventually output the signal using ultrasound. Could someone please explain why this set up doesn't work.
I'm receiving a serialized protocol buffer on the ZMQ Pull source and I'm expecting that if I just modulate then demodulate the signal I will get the same protobuf sent, back in the process that sent it (ZMQ push source sending it back). But that ends up not being the case and the byte pattern received after demodulating is off. Could someone explain why my set up doesn't work, Thank you again.
...ANSWER
Answered 2021-Mar-14 at 20:19You can either use pack instead of repack or you can use repack, but change the endianness from LSB to MSB.
QUESTION
Using DCMTK, I am trying to get the entire node of Content Sequence of .dcm SR files to extract measurements related to obstetrical scans. I use C-Find query. I am able to get the entire Content Sequence with Toshiba ultrasound machine but not with other brands. I don't think that this is a brand issue but the way I have set up the C-Find process. I am very new to this and am struggling to resolve the issue. I have included 2 log files below: one for the working case that successfully gets the entire node of Content Sequence tag, and another log for the non-working case that stops the process with an error "DIMSE Status: 0xc000: Error: Failed - Unable to process error". I appreciate any help or your insightful advice.
This the log for the non-working query
...ANSWER
Answered 2021-Feb-26 at 06:41Your requests only differ in that your non-working query queries for a different patient ID.
An obvious mistake in both queries is that for a SERIES-level request in STUDY-ROOT, you must not include a value for the Patient ID, but for the Study Instance UID. This is wrong in terms of DICOM, but Orthanc seems to be capable of handling it in general. This is however the only hint that I can obtain from your logs, so I would give it a try.
Please note, that the Content Sequence is not a mandatory Return Key for the C-FIND, so you can never rely on the SCP supporting it.
QUESTION
I am trying to find the time delay between two ultrasound pulses using Matlab, I have tried using xcorr and finddelay (which uses xcorr) but I get two different results. I would like to know why this is, and which I can consider to be the correct result. Ideally I would like to get xcorr working correctly as it would be useful to plot the cross-correlation.
Example data here.
...ANSWER
Answered 2021-Jan-22 at 10:37In MATLAB finddelay function is a m-file, so you can see the codes inside it.
If so, you will find that the finddelyfunction do the Normalized Cross-Correlation instead of Cross-Correlation. This is the reason that results of xcorr and finddelay are slightly different.
And I should note that for delay detection, Normalized Cross-Correlation (NCC) is recommended.

QUESTION
I have a data file containing different foetal ultrasound measurements. The measurements are collected at different points during pregnancy, like so:
...ANSWER
Answered 2020-Dec-02 at 16:05There is a magic command called query. This should do your work for now:
abdomCirc1st = df.query('MotherID == 0 and PregnancyID == 0 and gestationalAgeInWeeks <= 13')['abdomCirc'].max()
abdomCirc2nd = df.query('MotherID == 0 and PregnancyID == 0 and gestationalAgeInWeeks >= 14 and gestationalAgeInWeeks <= 26')['abdomCirc'].max()
abdomCirc3rd = df.query('MotherID == 0 and PregnancyID == 0 and gestationalAgeInWeeks >= 27 and gestationalAgeInWeeks <= 40')['abdomCirc'].max()
If you want something more automatic (and not manually changing the values of your ID's: MotherID and PregnancyID, every time for each different group of rows), you have to combine it with groupby (as you did on your own)
Check this as well: https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.query.html

Install ultrasound
You can use ultrasound like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
