Hamill Contrib Library

The following is a listing of the entire contents of this library for IDL. Click on an individual procedure name to view its header and source code. This listing is a shortened form of the much longer entire library help file. This may be handy for text searchs, be beware that some of these are huge and may take a long time to load or even crash your browser.

List of Routines

• CHECK_TYPE_DIM This function returns a TRUE or FALSE value (1 or 0) depending on the type of the variable, e.g. is it of type integer.
• FBAK_2D_MULTI This procedure will reconstruct a 3D volume from a set of projection images, using the filtered backprojection method and the formalism of nuclear medicine. In nuclear medicine, one refers to a "stack" of 2D images that comprise the 3D one; hence the name.
• IM_POISSON Add Poisson noise to an array.
• STILL_BUSY This function can be embedded inside an IDL code that is expected to run for a long time, announcing with printed messages that the code is still running. Unlike a PRINT statement in a loop, STILL_BUSY makes its announcements just once a minute.
• TVSTACK This procedure displays a multidimensional array (e.g. 3D) as a stack of images lain side by side, and by default scaled between the minimum and maximum values in the array. This is a method of visualizing 3D data sets, for example reconstructions of tracer uptake in nuclear medicine. For an image measuring NX by NY by NZ, the effect is somewhat the same
