hi my name is Shelly and today I'm going to show you how you can perform measurements with the clarius app there's several situations where you may want to perform a measurement so in this situation I'm just going to scan my patient's masseter muscle and once I freeze the image and I need to know how deep from the skin surface that masseter muscle is I go into the tools icon click on distance and I can tap on the skin surface and then into the masseter muscle and I can just make fine tuning adjustments to that measurement if I want to perform another measurement for example to determine how thick that masseter muscle is I simply tap the tools icon again select distance and I can perform another measurement when you're happy with those measurements you can go in take a picture if you want to redo them you can just click on the X icon just to delete them and that's how you perform measurements on the clarius app foreign
