[Rtk-users] 答复: About CR(Computed Radiography)

Thanks Simon and Cyril, I apoIogize for my confused question. I want to get a Radiofluoroscopic image rather than a Tomographic one from a phatom under certain angle. Is it possible to achieve this aim using RTK? 发件人: simon@gmail.com

[Rtk-users] Cupping Correction Coefficients

Hello, Does anyone have a piece code (doesn't have to be in C++) that can fit the coefficients for the cupping correction in rtk::WaterPrecorrectionImageFilter? Lotte ___ Rtk-users mailing list Rtk-users@public.kitware.com

Re: [Rtk-users] About CR(Computed Radiography)

Hi, If you mean Digitally Reconstructed Radiograph (DRR), this is what is called forward projection in RTK. See e.g. http://wiki.openrtk.org/index.php/RTK/Scripts/ForwardProjection Simon On Fri, Mar 24, 2017 at 9:54 AM, Cyril Mory wrote: > Hi Sam, > > > I think

Re: [Rtk-users] using rtk in matlab : input images for filters from matlab data types

Hi, SimpleRTK is compiled in single precision and Matlab uses double precision by default. So you need to do volume = py.SimpleRTK.GetImageFromArray(result.astype(py.numpy.float32)); A few remarks on your program: - there is a transpose that I renamed to cube, - you create volume_meta just to

Re: [Rtk-users] About CR(Computed Radiography)

Hi Sam, I think you need to ask a more precise question. RTK is primarily a tomography toolkit, but contains some pre-processing methods that might suit your needs. Can you describe what you are trying to do ? Cyril On 24/03/2017 02:31, 商 宏杰 wrote: Hi, Are there any classes of

Re: [Rtk-users] using rtk in matlab : input images for filters from matlab data types

thanks for the fast reply. Oops, it seems i missed that there is a backward operation of GetArrayFromImage, i.e. GetImageFromArray.. However, forward still doesn't work for me. This example code % geometry g = py.SimpleRTK.ThreeDCircularProjectionGeometry(); for i=0:359,
