All of the Dawei Veterinary for veterinary ultrasound have gain control, each type of machine adjusted in a different way, is one of the commonly adjusted scanning parameters, if these parameters are not too familiar with the recommendations do not casually adjust the parameters, because these parameters are important factors affecting the clarity of the image, today to give you a talk about the “gain” this parameter.
Most people think of “gain” as a brightness regulator, high gain will indeed make the image brighter, but understand its actual working principle will be very helpful. Gain is a parameter that amplifies the ultrasound signal uniformly, the reason why the screen becomes brighter when adjusting the gain is because the gain makes the image on the screen uniformly white, and it looks brighter.
Care should be taken not to over-adjust the gain, as over-adjustment of the parameter can cause the image to fade, resulting in loss of detail or artifacts.
Veterinary ultrasound imaging of deep structures
If you need to scan deeper places, you need to reduce the “frequency” parameter (about the frequency of the explanation of the veterinary ultrasound probe frequency on the imaging effect of what) but this will have an impact on the image clarity, then you can adjust the “gain” will be appropriate to amplify the ultrasound signal evenly. Ultrasound signal uniformly amplified to improve image quality.
Veterinary ultrasound probe poor contact
In the detection of the veterinary ultrasound probe needs to be close to the part being tested, there is air in the middle will seriously affect the image quality. When testing in vitro, you can first clean the dirt on the skin (if necessary, you can cut off the hair), and use the coupling agent to smear the test site and the probe to minimize the interference with the ultrasound signal. For rectal testing, remove as much feces as possible from the rectum and use a generous amount of lubricant as a contact medium to hold the probe tightly against the rectal wall.
Setting the brightness of the veterinary ultrasound monitor
When using veterinary ultrasound in a bright light environment you will find that the screen is not very clear to see and you will need to adjust the brightness of the screen to increase visibility. If the gain is adjusted to brighten at this time, it may result in an unclear image.
Veterinary ultrasound with increased gain settings for less shadows
In the detection of bladder stones and other dense tissues and gas in the body will find that there will be shadows in the image, affecting the image quality, resulting in inability to accurately determine, it is necessary to change the location of the test, or do not feed the livestock before the test to reduce the gas.
Shadows may also appear as edge artifacts, which appear at the edges of circular structures. If you experience this frequently, you can contact us.
When do you need to adjust the gain during the use of veterinary ultrasound
Generally when you buy our veterinary ultrasound machine, we will adjust the parameters before shipment, in the process of use does not need to make any parameter adjustment. However, if you feel that the screen image is rather dark, and do the brightness parameter adjustment still feel dark, you can increase the gain to optimize the brightness of the image, while retaining the details.
