Reference lines do not show using v0.1.9 for MRI-3T

[septembersoul]

Reference lines do not show using v0.1.9 for MRI-3T studies (axial/sagittal series). v0.1.8 works fine.

I'm using

• Cornerstone v2.3.0
• Tools v5.1.4
• DicomParser v1.8.7

I'm having the same issue, reverting to v0.1.8 also fixes it for me.

• cornerstone-core v2.6.0
• cornerstone-tools v6.0.2
• cornerstone-wado-image-loader v4.0.4

This function always returns 0 intersections

Maybe broken by @ladeirarodolfo in this commit? https://github.com/cornerstonejs/cornerstoneMath/commit/825a7b5551ed1bffa75ba84e380ddc7b365e7c3d

In my case issue appears here https://github.com/cornerstonejs/cornerstoneMath/blob/eb61ec1eda63623c766879e1b934776237001c93/src/Line3.js#L149

I changed it to if (s >= 1.1 || isNaN(s)) and reference lines became visible. Value of s variable was about 1.0938...
