Use of X-ray film: technical discussion with example images

Your results look more like too little than too much agitation, but only you know exactly what you did
Higher dilutions for longer development times can help and are a viable option depending on which problem you're trying to solve.
Since this is a mammography film, I assume it's single sided?

Agitation that works for me is gentle lifting of (flat-bottomed) tray once, north/south east/west. Then let rest for one minute. This works well for double-sided, 8x10, 14x17. I use Pyrocat-HD or Blazinol (Rodinal deriviative).

I use a similar pattern. If more agitation is needed for particular films or developers i lift 3 corners each 30 seconds.

If you are using X-ray film, you may want to download the free paper I just posted on this forum on SLIMTs. It specifically discusses reducing the contrast of X-ray film with SLIMTs.

Constantly shaking the tray from left to right ...

2nd try with pre-soaking the film in 3% soda solution to get rid of the anti-halation layer for 4 mins. The developers react more quickly but the clouds are still there. Next try will be indeed with Rodinal or HC110 ...

Dilute Rodinal 1/100

try 7 to 10 minutes medium agitation

This.
Your dev times are too short using those developers (at what I assume is "normal" strength).

I develop any of my X-ray film (blue, green, or the Kodak one-sided only) with Xtol (1+1) or Rodinal (1+50) for 6 minutes, and always obtain satisfactory results. Here is an example using the Kodak one-sided-emulsion film;

Hello, this is my first post

I'm interested in trying Fuji Super HR-T (green) X-ray 8x10 film in my large format 4x5 camera.

Just ordered it, still waiting to receive. Description says that emulsion is on one side only, hopefully it's true.

Planning to use my paper trimmer to cut sheets down to 4x5.

Has anyone used this HR-T film before? Any word of advice on ISO rating and develpoing?

Thank you!

Fuji HR-T is all I have used.

It is double-sided.

Rodinal 1:100 for 6-7 minutes is my standard development time - nowadays, in trays, carefully, so as not to scratch the emulsion.
