check the screenshot I'm gonna upload in the following post with a comparison between measure lines in iQ-VIEW (on the left) and RadiAnt (on the right).

asyou all may see, iQ-VIEW puts a small tick in the middle of the line segment which indicates the half of the measured line, whilst RadiAnt show only a simple segment.

that "half tick" is very useful when you deal with sagital MR or DX of the lumbar spine and you wanna grade spondylolisthesis.

if the posterior border of L5 is still close to the posteriore border of S1 is a grade 1.
if it's closer to the half of S1 is a grade 2 and if it's beyond the half of S1 is a grade 3, and finally if it's close to the anterior margin of S1 is a grade 4.

when I read MRI with iQ-VIEW that small tick at the middle of the line segment is an immediate and useful visual hint that helps me doing a faster grading.

I'd like to have something similar in RadiAnt.
probably it should be an option... user should let be free to decide wheter to have simple line segments or to display that "half tick".

think about it.

here's the screenshot I'm talking about:

Thank you Tommy. This option is certainly worth adding to the viewer.

A "half-tick" option was added in RadiAnt DICOM Viewer 4.1.16 Beta.
