Question

Hi there. I have been experimenting with IQWORKS (which is brilliant) and some uniformity images of the CATPHAN 600. I have 16 images (DICOM format) of the CATPHAN taken from a 16 slice scanner and I was wondering how to put the mean and standard deviation of ROI analysis from all 16 slices (opened in a single multi-layered image) into a single detailed report. I have created the analysis tree I want which has a 100 mm x 100 mm (physical) elliptical ROI anchored at the centre of the phantom (processed central point of the phantom edge). I can obtain a report for each slice individually, however wish for all mean and SD results for all 16 slices to be on one report. If I run the analysis tree on all images, the report only gives the mean and SD results from the image currently selected in the multi-layered image window.

If, on the other hand, I load up the images in individual windows and run the tree on all images I do get the results I desire, however the report is simply 16 reports next to each other. I tried deselecting all image information possible (and the copy of the image itself) and leaving z-position and file name for each image which does reduce the report length, however is not ideal.

(When trying to deselect all image information, I also noticed that 'FOCAL_SPOT(S)' and 'GENERATOR_POWER' are not in the image information list and are therefore not de-selectable, but are present on the report)

Another option is to open the CSV file in excel and use the information from here, but I was wondering if it was possible for IQWORKS to produce the report in its standard format.

I attended the meeting in Birmingham, where you may have covered this, however I can't figure it out!

Any help would be very much appreciated. Sorry for the ridiculously long question!

Thanks

Using a layered image, in the properties of your ellipse you should be able to select "All Layers" in the Layer Approach field. At first glance I thought this would solve this problem. But it doesn't. On the WishList on this website there is a "Perform calculations on [report] data" so I don't think this has been implemented yet. Not really a solution, sorry!
