I'm budgeting for an improved CT Density phantom for later this year, currently I just use a CatPhan. I'm seeing offerings from SunNuclear, CIRS, Phantom Lab. Preferably something that works with DoseLab -- I'd prefer not to add any more proprietary software for analysis.
Does anyone have a favorite?
TIA!
I may be late to the party with some of this, but I just wanted to share some slicer settings that have changed the way I'm designing imaging cubes.
The slicer setting is "Fill multiline". It lets you create big chonky infill structures by making them arbitrarily thick -- ideal for automated image registration with CBCT.
I used to spend a lot of time creating modeled geometries to give the registration algorithm something to work with. The Fill Multiline has simplified the modeling. You do need to play with the infill pattern and possibly rotate your model on the bed to control where the lines fall to prevent a nasty line crossing in front of something you want to see on a kV or MV 2D image, but it only takes a minute. The end result are imaging cubes that automatically register perfectly with the reference CT. No manual tweaking needed even with ugly tungsten artifacts.
Anyhow, That's all! Just thought I'd share this simple tip!
And... If you're not using fuzzy skin 0.1/0.1 it will change your life.
For many of us, words are not our first language.

I think the benefits of being able to post a screenshot are obvious. What is less obvious is whether this would make more work for the mods... I respect their time and don't want to add to the burden.
​
Could we maybe flip the switch and see? If it turns out to have been a mistake then I fully support turning it back off.

This has been many months in the making and is punching above its weight in clinical usefulness.
You can get the model for free at this link! Foot Immobilizer on Printables
Essentially a big 3d printed foot rest that elevates the foot so that lateral (ish) fields can be used while missing the contralateral leg. It has been far superior to our previous methods (big vac bags) for positioning a foot or ankle. The therapists love the setup.
With the recent run we've seen of Benign Low Dose XRT it's been getting good use.
It does employ the existing standard U-Frame Baseplates as well as an aquaplast style mask.
If you're thinking about getting a BIG 3D printer for your department, perhaps this will push administration over the edge. It will generate a Complex Tx Device charge for the mask and you can point to that money as a way to pay for the printer in just a few uses.
It does require a printer larger than the usual 256x256mm (X1C etc). If people have a need and wish to spend department money, I have a college engineering student at home for the summer who I can put to work. He can put it up on Etsy.
Please with the feedback!

Well, I've been in a death match with the Soncotta Amped ESP32 https://sonocotta.com/amped-esp32/ the past few days.
I've written the firmware/yaml as the 3 various different supported flavor versions..
While it plays acceptably from the MA interface (occasional stutters), and it appears in the Spotify Connect players from within the spotify android app, when tasked with playing, it gives all the appearance of playing the track, but no sound!
Anyhow, I'm hoping someone has seen this behavior. I'm about to put this in the "loss" column.
TIA!
My notes in case it saves someone else some trouble. Wiring is obvious (Red+, Black -,White data), WLED settings took some wrestling. Seems there are 2x WS2811 chips per spotlight. One for the RGB and one for the White. With these settings the "White Light Group" gets warmer as you move color choice towards Green? (Maybe someone can tell me what I've done wrong).
Node 1 is Light1 White, Node 2 is Light1 RGB,.... repeating.
Still, it works, and is working with Home Assistant. Using a couple of the govee spotlights with a Gledopto WLED controller @ 24V. The original controller suffered water damage.
