Hi there, I was hoping to set up an ORTHANC DICOM server on my work computer and I guess computer programming isn't my strength. I was just wondering if anyone has much experience with this and would be willing to field a couple of questions from me that would help me get this set up. In...

Hi there, Was just wondering if anyone knew of any good freeware for generating X-ray spectra from a standard Tungsten anode that you might see in medical radiography? Would be good if it could export data as well, but yeah and just wanting something that can potentially generate the spectra...

Thanks again for taking the time to explain this stuff to me Imabug. So basically you are saying that if you have used a 240 scan angle it means that this is all the information you have used to reconstruct the slice, but you have not actually reduced dose. Even with prospective gating the tube...

Sorry for having to ask another question, but there is just one more thing that I want to get my head around. Let's say you have this protocol: Standard Resolution 64/40 x 0.625 collimation 2.5mm thickness 40/25 mm increment 240 scan angle 0.4s rotation 120 kv 55-165 mas 512...

Thanks for the information imabug. I have to say that this topic, although interesting, is also quite confusing at the same time. So I really appreciate you straightening that point out for me.

I've recently started a mini project on typical doses that patients receive when having particular CT examinations and there is just something that I don't really understand that I was hoping someone here might be able to help out with. Now when a doctor takes some CT images the CT machine...

Thanks for the reply Integral. Sorry about that but I was only providing a segment of the code so that's why you saw that infocol wasn't initialised. I'm not sure if you're interested at all, but I found out what the problem was. When you specify the formula with the dynamic range you must put...

Hi I have been having a problem with a section of my code in the macro that I've created. The problem is that the formulae that I want to use aren't working and soe I get a "##Name" error in the cells where the formula is supposed to have worked. Patientrange = Range(PatAgeLet & "2" & ":"...

Thanks for that Fred. I've modified it now so that I've broken the "range" up into a beginning point and end point and so now I offset each part. So as you can see by the code below I have a beginning cell (beg) and an end cell (fin). Now when I put a MsgBox to print both of these cell...

Hi I just have a quick question about a VBA program I've been writing. It's mostly working, but there is a slight problem when I use the "Selection.Offset" capability. For example, if I had a range selected of $C$23:$C$34 then I would have thought that if I did "MsgBox Selection.Offset(0...

Thanks for that! After much more searching I have found a couple of programs that I think do what I want them to do so I will check them out.

Hi guys, I was just wondering if any of you knew if there have been any programs that have been written by people to perform character recognition in an image file. That is, you have an image of written text and you want to somehow recognise and extract characters. So for example, if you had...

Hi I am writing a program in Matlab and I want to search a string within a cell to identify where certain characters start and end. However, once I identify the start and end points I want to extract all the characters within that range. So for example let's say that I have a 25 row by 1...

Homework Statement I've created a function inside IDL and I want to be able to specify the binsize. That is, I want to have: result = myfunction(array, keyword) Whenever I add the keyword in the brackets there it says: "Keyword parameters not allowed in call." 2. Relevant code...

Homework Statement By the convolution theorem one would expect that if you convolved your image with a kernel in the spatial domain, you would get the exact same result if you multiplied the FFT of the image array by the FFT of the kernel. My problem is that I don't get the same results...
