Viewing my CT Scan in 3D using Linux


Screenshot of a user interface showing a 2D view and a 3D view of my scan.

Several years ago, I had a CT scan of my jaw. The dentist wasn't sure if she was allowed to give me a copy of the scan, which led me to ask "who owns the copyright to my medical images?" I still don't have an answer to the copyright question - but I do now […]

The tooth, the whole tooth, and nothing but the tooth


X-ray of teeth on a computer monitor.

You know that ice-breaker game "Two Truths And A Lie"? When I'm forced into some mandatory office fun, I always say... I've sat in the seat of a space shuttle. I still have two of my baby teeth. I used to be a voice-over artist. Well, one of those truths is about to come crashing […]

Nurses should spend less time helping patients and more time ordering bandages


Crop of an oil painting. The Agnew Clinic (or The Clinic of Dr. Agnew) an 1889 oil painting by American artist Thomas Eakins. It shows three male doctors operating on a patient. A female nurse looks on.

I was speaking to the absolute epitome of a pub bore. Flapping his jaws about how the problem with the NHS was too many admin staff doing absolutely nothing. "Quite right!" I said, feverishly agreeing with his red-faced ranting, "Nurses should spend less time helping patients and more time ordering bandages!" He paused, slightly, as […]

Can this new probiotic reduce lactose intolerance?


A small pharmaceutical bottle. It easily fits in my hand.

I ordered some pills off the Internet and swallowed them! What could possibly go wrong? Let's get one thing out of the way first. I am not a doctor. I don't even play one on TV. This blog post is not medical advice.

Where are the high-tech dental implants?

When I was a kid, I had two of my adult teeth surgically removed. As such, I still have two of my baby teeth. And, as I get older, they're starting to wear down. At every dental check-up my dentist prods them, gives them a wiggle, and sometimes takes an x-ray. "Well," they say, "They're […]

You have no idea of the changes which are coming


The New National Health Service.

I wrote this before the pandemic. I chickened out of publishing it because I was working for NHSX at the time. Some of these things have come to pass. Some are yet to come. I'll never forget the look of horror on my professor's face when I told him I didn't think his university course […]

Bluetooth MAC, K-Anonymity, and Population Privacy


List of Bluetooth devices.

I recently went to a university hackathon, where students were trying to invent novel ways to help prevent pandemics. This was purely an academic exercise - they were not developing a fully-fledged app, nor were they creating official policies. I spent some time with one group discussing the privacy implications of what they had built. […]

I've broken myself - dealing with RSI

I've recently been suffering from a nasty bout of RSI. Thanks to the NHS, I know it isn't full Carpal Tunnel Syndrome, which is good. But I do need to take better care of myself. My usual kit is the MS 4000 ergonomic keyboard and an Evoluent Vertical Mouse. But recently I've been travelling a […]

Who owns the copyright to my medical images?


X-ray of teeth on a computer monitor.

I popped round to an NHS dentist a few months ago - and they stuck my head on one of these contraptions. The Kodak 8000C takes a panoramic X-ray, giving a superior view of your teeth. Nifty. The dentist showed me where my wisdom teeth were and I was impressed with how high resolution the […]

A Right Pain In The Balls


Photo of a man in blue jeans clutching his crotch with both hands.

The universe had a moment of quantum indecision while I was sat in a doctors' waiting room. It flickered randomly between playing nicely and messing with my head. I tried to collapse the probabilities by uttering a most unusual secular prayer for a man... Don't be pretty.... don't be pretty... don't be... "Mr Eden?" Maybe […]
