We bought a knockoff Lego launchpad kit from China for our Saturn V rocket so you don't have to

I've seen it at our scouts (figure this out if you have to) and has models in te local LEGO store.

NHS England offers £15m to AI firms for software that helps with stroke victims' treatment as COVID-19 stretches service

Dante Alighieri

Edge cases

My concern would be that while it may be possible to automate a stroke/ischaemia/haemorrhage ML solution, the problem is that a small number have other mimics - tumours, paraneoplastic, encephalitis to name but a few. I doubt the training set will contain enough of these to make it safe or useful.

Pretending the issue is stroke/not stroke and haemorrhage/no bleed is a failure to properly understand the issue. You need to teach it a much larger part of brain CT interpretation*

And spotting a bleed on an acute CT is trivial - white bits where they don't belong, it's not subtle.

Hyperacute ischaemia is harder, but if in thrombolysis window you are going to get to roll the dice.

This appears to be a solution looking for a problem. Stroke teams and Radiologists do this daily and have sufficient expertise to recognise the odd ones. There are other more difficult areas where computer support is more appropriate, eg lung nodule analysis and marking.

Humans being humans have to be careful not to rely on such tools and miss the unmarked ones or other pathologies

{thrombolysis is a double edged sword - it takes a normal distribution and moves cases to the ends - much better or much worse/dead}

*I mention CT and not MRI, as acute assessment with MRI is exceptional in the true sense of the word.

Re: Mobile Phones

No - that is NHS identity

This is a permission to work system (see my response above) : are all necessary checks in place and trusting another organisation to do this for you.

There are plenty of ways to establish your bona-fides, not least of which is simply logging in to your NHS email!

Dante Alighieri


NHS Identity is basically a remote access token to a live clinical system.

NHS Passports which have been discussed in my region for the last year (so they are not new or related to COVID!) are meant to bundle your Occ Health data, Mandatory Training, DBS and professional registration checks in some form of bundle that the relevant HR can determine that these are in place (but not necessarily share the actual data) - one Trust guaranteeing that the staff member is correctly checked and safe to allow on your premises (an NHS equivalent of the schemes we have for contractors on-site)

Hope this helps

Oracle adds Arm-powered servers with up to 160 cores to its cloud – must be why it sunk millions into Ampere

It was meant to be more a comment on Oracle's billing model than the architecture - I exaggerated RISC/CISC for effect, so apologies for upsetting the technically more competent than me regarding this.

I took the original post as what's the trap and suggested a possibility.

Apart from an excellent Jethro Tull track,

genuine question from a hobbyist* : is it too late to sniff traffic and reverse engineer protocol to allow an on premises re-direct of traffic to believe it is seeing the shyster server?

Is it time to do this for other IoT / smart tellies etc (PiHole recognised)

I've flirted with automation stuff as a concept for around 5mS (which as Commander Data pointed out is an incredibly long time) but unless I can run it on an open home automation server I control it is all someone else's property.

Leeds hospital launches campaign to 'axe the fax'

Dante Alighieri

I find the article a little odd.

It is as though Leeds is the first hospital in the UK to think of doing this.

Mine a bit further north has already ripped them all out. perhaps Leeds should ask for advice rather than pretend to be an authority.

We accept radiology referrals from consultant NHS.net accounts - it is an electronic signature in its own right, for those based outside our organisation. Internally we have a request system which you can use or be told to resubmit your scrap of paper electronically. Almost completely paperless referrals now.

Re fax ct scans etc - you can email/scan/fax a report - the images not so much.

It's my day job.

Imagine you're having a CT scan and malware alters the radiation levels – it's doable

Dante Alighieri

Radiation Safety + MRI


I am a Radiologist.

I have an interest in radiation safety.

There is NO limit to the dose my CT scanner gives a patient.

I authorise the use of radiation. I have had patients receive >50mSv for a diagnostic test.

The UK accepted rate for cancer induction is 1:20000 / mSv.

My patient has a death risk of 1:400 to look for a possible pathology they have a <1:4000 of having.

Dose is cumulative

Induction time lag is around 15-20 years.

I'll fry your granny - but not your kids.

Comparing targetted radiotherapy doses to tiny areas is not appropriate.

Yes we run XP / 7 for our underlying systems as the suppliers will not warrant any other environment.

The business end (custom hardware) works with its own internal systems (think CNC machine or 3d printer) screwing with the dose regulators is beyond the XP bit. When that goes down I have shut several scanners over the years - including writing one off! Mr Popular...

Dose is controlled by exposure factors set at the operators console (the XP bit) and the area covered and how many times.

The first acknowledged Fukishima related cancer is at a dose of 10-20mSv.

In the larger adult this dose is not uncommon on our current scanner(s) which are not particularly low dose.

New algorithms and technology is reducing delivered dose - but better tech is leading to multi phase exams that increase dose.

We have patients with accumulated doses of >200mSv, in an age range where this is an issue and a worse than 1:100 risk of death from their radiology scans.

Re MRI : it is a giant microwave. never mind there is no ionising radiation, it is perfectly possible to induce fits from neuronal stimulation from aggressive gradients or literally cook some one with RF energy.

We cannot air gap the provider need dial in access for fault finding and remote management when required.

We run NTPc on CT that connect to GMT-8 (ish) as that that is the worldwide system clock.

Radiology runs on a private subnet the firewall and bridging is managed.

Denial of service : highly likely

Manipulation of target devices : low - too varied, custom device v operators console manipulation

Medical Grade Monitors

I use these. Professionally.

They are pointless unless in a controlled environment <10lux for diagnosis.

Medical monitors outside this are pointless. Accurate DICOM reproduction is nice. If they are <2MP they are not diagnostic, If they are in an uncontroled environment they are not diagnostic

Outside of proper diagnostic offices they are an entirely avoidable and unncesssary expense.

DOI : I have stopped unnecessary over-specced monitors being deployed across an organisation, and also making sure diagnostic screens are available in the appropriate departments with explicit "your environment is non-diagnostic" warnings.

Many think tha the CT and MR scans are the most details - they aren't 512x512, 10 bit pixel depth. Most bog standard monitors far exceed anything necessary.

"plain film" x-rays - much more challenging!
