First time that I see that something can be connected to an IPhone. I wonder if you need special privileges from Apple, or there is an API available that can do some data (serial ?) transfer.

I don’t think there is any public API for this: you probably have to be in the MFI program to send data through the Lightning port.

It has nothing to do with the phone or the software it's the device, which if you could get down to a hundred $ or so it could be used by farmers of livestock. This could be a revolution, but the Ultrasound Scanners need to be in the hands of low income farmers then imagine how quickly the dam ecosystem would develop across to humans. I've been looking to get a cheap one from China, but you can't, I'm not sure why, b…

I'm not sure you can mass market it. You need medical knowledge to make sense of ultrasound images. Unless you plan to use it for something else than medical

A lot of farmers have a surprising amount of medical knowledge. It is common for farmers to do a lot of simple medical procedures on their animals. Large farmers in the US already have ultrasound machines for their cows - they don't need to know everything about how to read them to know signs that mean call in help (thus saving a lot of money)

The price of a portable ultrasound has little to do with the electronics as far as I understand it. Production of the probe's ceramic transducer is expensive.

I guess it's hard to make a decent one. You can get scanners from about $600 up from china. Apparently you need an array of transducers which cost a bit.

I'm not sure why the Africans need a $2000+ butterfly scanner rather than this kind of thing https://www.aliexpress.com/item/Veterinary-ultrasound-machin... ?

I presume the Chinese one isn't as good. The images do look a bit blurry.

In the article, the dr uploads the scan for confirmation. I agree the average person shouldn’t be trying to self diagnose from a scan, but anyone could upload a scan to a dr they couldn’t travel to.

Yes you are right, except for the fact that this probe uses a silicon chip instead of a piezoeletric ceramic transducer, and that's exactly the reason why it costs 2000 dollars.

Knowledge of animal anatomy or certain medical procedures are no help in trying to decipher an ultrasound image. I don't think you can just plop an ultrasound scanner into a farmer's hands and have them to do anything truly useful with it, to justify the investment. Not without training.

One option would probably be to have a doctor remotely in a "command center" just looking at these as they are uploaded from the field, and relaying the diagnosis back to the farmer.

I thought the hardware manufacturer needed to get MFI approval allow for developers to distribute apps that rely on ExternalAccessory?
