Hi,

Thank you for your hard work in development.

I had been a little busy so i hadn't been able to test the improvements done, but here are the things I still see that can be improved:

Bugs

1. When clicking the reset button, It always enables windowing and loads pixel data (Why does it always have to load pixel data?, no matter how many times it have been done before)

2. When clicking on the LINES button it changes color and it appears as selected, but when doing the first measure, the button changes back to the normal color and the user doesn't know what tool it's using at the moment

3. Similar to number 2. When changing layout, and choosing a tool, it should enable the same tool for each windows of the layout.

This is because, you don't know by memory what was the las tool that was used in each window, So the ideal scenario is that if you have PROBE selected, and it shows in the menu bar that probe is selected, it should let you use the probe in each of the windows of the layout.

4. I have a problem with several studies in which WL/WW values are really big, so when doing windowing, the change is so small that it almost seems as if nothing is been done. Please check attached example for reference.

Suggestions:

1. It should be possible to have a measurement selected, and be able to do a scroll of the images in a series. When clicking on probe, or magnify you can do a scroll, but when LINE is selected, you have to deselect LINE in order of be able of doing a scroll

2. It should be a little more intuitive to reposition or extend measurements. In other apps it's just a matter of clicking, holding and moving, one of the points of the drawing to change the drawing.

3. When doing a new measure, you should be able to clic wherever you want after you haver already started doing a new measure, no matter if there are lines or angles in any of the points clicked. Right now if you are drawing an angle, and teh second or third of the points of the angle to measure is over a previous measure, it selects the previous measure, and you can't draw the angle you were drawing.

4. Is it possible for Oviyam to load archived studies of the same patient ID without the need of entering aditional fields in the URL, other than the UID?

Thank you

On behalf of the Oviyam team, I really appreciate your detailed feedback. 

4. I have a problem with several studies in which WL/WW values are really big, so when doing windowing, the change is so small that it almost seems as if nothing is been done. Please check attached example for reference.

I had a quick testing on this using the DICOM image attached by you. Yes, windowing changes are terribly slow. Have to work on it. Looks like there are additional tags "Smallest Image Pixel Value / Largest Image Pixel Value" values ranging from 38500 to 63635 related to windowing present in the dataset of image attached. We understand that we have to take it into account when preparing the lookup table for windowing manipulation.

We will go through the other bugs and suggestions reported and update. Once again thank you for the detailed test report.
