Ultrasound Guidance
I have one of the $900 Chinese handheld ultrasound machines that you can find on Amazon under a bunch of different “brands” with a standard convex probe. Any tips for using and settings? When I played around with it on myself, I didn’t see much difference as I made changes (such as frequency, gain, etc). I saw the biggest difference with frequency but I wasn’t able to identify the usefulness of the different frequencies.

I don’t have that machine but can help you with what the settings are for:
Gain. This one is for lighter and darker. I like to turn that all the way up especially on short bred animals.
Frequency- different penetration. How is your machine measuring? Is it showing numbers or something like Pen, Res? Mine doesn’t do the pen and res, but if you’re is measuring numbers the higher the number for the bigger the animal. But this one really just needs to be played with per animal. If your having a hard time finding something then just play around with it.
Gain- it’s like zooming in and out. I like to start with it zoomed out (sorry I don’t know if that is up or down I just know I turn my job to the left to zoom out) and when something catches my eye then I will zoom in.
Hope this helps

I understand the basics of ultrasound. I use it occasionally in the course of my work... only it's on humans... and it's hospital grade. When I tried ultrasounding my arm (lots of blood vessels in there to practice with) I didn't notice much, if any, change when I tried changing the settings. I was also hoping for a "best practices" starting settings when doing goat pregnancy. When probing humans, I have certain settings I start with which vary based on what I'm looking for and it usually gets me a better image faster because I'm starting closer to where I'll end up.I don’t have that machine but can help you with what the settings are for:

This machine and the probe are not going to pick up blood vessels in a arm. It’s made for pregnancy only and it’s not even a small fraction of the quality of what you are working with.
Basic start settings, pretty much what I said with the settings. Depending on the doe on what I will start with on frequency. A small doe first timer I start at a different setting then a big deep bodied doe. Gain I always put at 100 especially with very short bred does. It makes any fetuses (will come out white) stand out more in the black (fluid). And I like having it zoomed way out to cover more and then zoom in on anything of interest, again especially on short bred. Probably when you use it on a bred doe you will understand what I’m trying to say more

I was pleasantly surprised on what I picked up in my arm. I found my artery clear enough that I could have accessed it if I needed to. The probe wasn't the right probe for it so I wasn't expecting much. I appreciate the suggestion of starting with gain at max, especially since I wouldn't normally. I'll give it a try tonight when I get off work. I have 4 does pregn... err, bred to practice on. One is in her last 4 weeks or so. The latest is 21 days since bred. The other two are spread out in between. Since I'm used to the linear and phased-array probes, I need to work on technique just handling the convex probe. The other probes are easier to get the whole probe in contact since they're straight/flat. Having a starting point, like gain-at-100, will help so I have one less thing to juggle. I caught a kid's heart beating a couple of nights ago but it was all luck, but I was absolutely thrilled! I haven't been able to do it again yet.This machine and the probe are not going to pick up blood vessels in a arm.
