Now for the probably over-hyped bonus.

 

For a bit of fun I decided to throw some balls onto the CT Scanner. I was hoping that the CT would be able to demonstrate the cover and mantle layers.

I didn't scan all 4 boxes as I thought that would be going a bit overboard. I only uploaded a few images, as they were representative. The scanner I used is capable of 0.3mm slices, and reconstructions in any plane but I thought it best to just provide a brief overview.

The images are of Box 3

2067045549_CT1Box3.png.35699126c09a53e40b192193f4c4dda4.png

The large imperfection in ball 10 is even more clearly shown. As a technical note, the black round the bright dot is most probably artefact from the high density, and not a "hole" in the outer core. I measured the density of the imperfection, and it is almost certain to be metallic.

 

No balls were harmed during this procedure, and the likelihood of the balls glowing in the dark (despite Marvel comics and @PMookie's beliefs) is negligible

 

 

Yep. Those specs are glowing… Just don’t keep those in your pocket next to your, um, “keys”. 😂😂😂😂

Now you've ruined it for me. I was hoping people would think I was incredibly committed to golf ball QA, not just going stir crazy. At this rate 4 dozen balls may well see out my playing career😅

From a quality standpoint I would say those are spot on. No large imperfections or off center cores. The imperfections to me seemed mild at worst

Cool, but like, what's the prognosis? Is it malignant? Are we talking 3 holes to live? 9?

My recent purchase of 4 dozen Srixon Z Star XV's arrived yesterday, so it was time to get to work (actually get to playing around with my balls at work😅)

 

I started by x-raying each box. I only performed 1 view of each ball, a dozen at a time.  I left the balls in their sleeves and boxes but removed the lid from the box. I tried to obtain sharp but not noisy images, so used a scatter reduction grid to tidy things up a bit.

 

The density difference and thin layers made it impossible to visualise the skin from the mantle layer, but the combined outer 2 layers and the inner core are easily visualised.

The normal radiographic rule is 2 views perpendicular to each other, which  I only applied to one sleeve. My rationale was that significantly non centred cores would likely be apparent on a single view, and small high density imperfections probably aren't very likely to cause problems when playing.  I did do a second view of one sleeve to determine (and demonstrate) if the high density imperfection was in the inner core or the outer core.

I have marked box 1 balls 4 and 10, and box 4 ball 6 to keep them separate. I will play a couple of practice holes with them to see if I can determine any difference in playing characteristics.

 

Many years ago I used to install and maintain cardiovascular X-Ray systems. This post makes me most happy.

So while cool, as a chemist,  I cringe seeing a ct used on golf balls when there is a helium shortage (for those who don't know, helium keeps the magnets cold and prevent them from seizing and preserving their magnetic field strength. )

I bought a couple dozen previous year Srixon Z-Star XVs and tested them in water with dissolved epsom salts. They barely float in that solution. I marked the top of each ball when it stopped spinning. When I re-spun each ball none of them came up to the same place twice. That means every one was extremely well balanced. Good quality balls. Long hitting off the tee and high spin around the greens too.

No helium in CT’s, that’s MRI. CT is really just fancy x-ray. The impact of helium shortages on MRI could be catastrophic somewhere down the road.

Interesting! I personally like Srixon and play the Q-Star Tour, as my driver swing speed is low to mid-80's, so around 60 compression works for me. I used to play Z-Star but with my current speed no reason to pay more per dozen. Plus, Srixon promotions are usually the best.

Did the images out of hours when no patients booked while on my break. It's at the site I manage and my manager has no problem with it.

What a great use of X Ray and CT scanners. I guess the plandemic has left a lot of people in the medical community with nothing better to do.

We're currently in lockdown, and our bookings are down as a result. Fortunately our area is doing ok at the moment.

I found it almost therapeutic after dealing with the daily stress of dealing with pandemic response, especially making sure we have adequate supplies of PPE to keep my staff safe and healthy.

So, I think we can all agree that MGS needs to invest in a CT Scan and an X-ray machine. Now, if we could only get the MRI in the study we can analyze the beJesus out of these balls. LOL Great work from a true golfaholic.

 

To put my technical hat on, MRI wouldn't be much use, as it basically demonstrates water, which hopefully modern balls don't have much of.

Thanks...I had to laugh as I've had MRI's and CT scans lately -- dealing with a plasmacytoma on my L4 vertebrae.  I have another coming up in October so I may try and stick a sleeve in my pocket...who knows what that would do to those who read these things...
