Dear Developers and Users
I want to create an image, with a certain matrix and pixel sizes, of the shadows of the segments in RTSTRUCTURE (one of the inputs used in SlicerRT) on a plan at a distance of 160 cm from the target and perpendicular to the central axis of beam.
Please suppose that I want the matrix size of this image to be equal to 1024x1024 and pixel size to be equal to 0.4x0.4 mm.
It is assumed that the source of producing these shadows is the target of the linear accelerator (LINAC).
I have shown this in the following figure.
In this figure, the radiation field (Beam) is seen in green. The plane I talked about is displayed in yellow.
At this figure, the segments that I want shadows to be created on this plan include the following:
RightLungCTNormal,
LeftLungCTNormal,
HEARTCTNormal,
CTVCTNormal and
LADCTNormal
I want the pixel value of each shadow area of the segments to be specific and different from the other.
Please guide me.
Best regards.
