Hi all,
just to summarize this thread: As Alex said, it is crucial to keep your images in DICOM (or, if necessary, at least in other image formats dedicated for medical images like NRRD or NIFTI) as all the important image meta information like the physical dimensions of a pixel and the space between pixels is lost otherwise. The squares do not alter the actual measurement and their sole purpose is to provde an area for mouse interaction. If you feel like you can't measure accurately enough by moving the squares around, please note than you can actually measure even in subpixel-accuracy: we recommend that you zoom into the image (press and hold the right mouse button on your image and move the mouse for zooming). After you zoomed into your image and it is not shown completely in the windows anymore, you probably also want to pan the image. You can do this in the same fashion as zoomig but with the middle mouse button (in most cases the middle mouse button is the mouse wheel, that can also be *pressed* down instead of turned). As the square mouse handles of measurements stay the same size when zooming, the accuracy then is by far greater than the image resolution. If you still want to get rid of the squares, for example for aesthetic reasons, you can do so in the Properties View. In MITK 2018.04 there are two icons in the Data toolbar, a list icon and a box icon. The Property View is represented by the list icon. If you only see the word Data in your toolbar and an arrow, click on "Data" to unfold the toolbar and see the icons. Open the Property View and make sure to select your measurement, for example your line, in the Data Manager. The Property List then is filled by a lot of data and its title shows the name of your measurement in curved brackets. It should be enough to enter con into the filter at the very top of the View and the only property left is planarfigure->drawcontrolpoints, providing a checkbox in the value column that you can check and uncheck to control the visibility of the squares. Again, this is really not necessary at all to get accurate measurements, just zoom in a little. Hope that helps.

If spacing gets lost (e.g. when export images) this will affect the measurements. Can you explain exactly what type of images you load into MITK and how those images are generated?

It is tedious to get rid of the boxes for every single line by going to properties and unchecking the box each time! My question to Alexander would be - what standards do you take for your measurements as they seem to differ from the standards on our voluson machine. We have been using our voluson machine as our gold standard machine (much like most worldwide institutes) and the value of measurement calculated from the voluson and MITK images caliper are different by minimum 2-3 mm (with MITK overmeasuring - I have checked that by removing the boxes at the end as per your instructions) Let us know what you think about the same. And also if anything can be done to rectify this.

Usually those squares don’t exceed the size of the line itself by much. Zooming into the image (right mouse button and move mouse up) might help as well, as the size of the square is not affected by zooming. Another possibility would be to disable drawing of the control points in the properties of the drawn line: 1. Select line in Data Manager 2. Open Properties plugin 3. Add “control” as Filter 4. Disable property “drawcontrolpoints” by unclicking the check box next to it. Von: Alice Self [mailto:alice.s...@wrh.ox.ac.uk] Gesendet: Freitag, 18.

So to be 100% clear (it’s a bit difficult to clarify without pictures and speaking so sorry!) you are saying that the measurement that MITK generates is from the middle of one of the little squares to the middle of the other square rather than from the medial border of one square to the medial border of the other? If this is the case, why is a square used rather than a cross which would make that clearer?

For the Measurement plugin it will be the center point of those little squares that indicate the ends of the line. Alexander Von: Alice Self [mailto:alice.s...@wrh.ox.ac.uk] Gesendet: Donnerstag, 17.

When drawing a line you want to measure there are little squares at the end of any line drawn and it is not clear whether you need to place the middle of the box over the end point of the structure you want to measure or whether it must be aligned with some other part of the caliper box Many thanks Alice Alice [YDX674-9V89]
