Ultrasound is coming into ever more widespread use, and an app that trains health personnel to interpret ultrasound images has just been developed.
A new app will offer healthcare personnel training and experience in interpreting ultrasound images.
“The threshold for the use of ultrasound is steadily being lowered, and more and more people need to learn to interpret what they see on the images. For this reason, it is important to expose them to a wide range of ultrasound images,” says SINTEF research scientist Frank Lindseth.
Could Reduce Need for Anesthesia
Most of us associate ultrasound with fetal examinations, where the technique is used to check that the fetus is developing properly. What many people still do not realize is that ultrasound can now image nearly all parts of the body, and that the images can be used in the study, for example, of the prostate gland and the heart, as well as for assistance and guidance in different types of surgical operations, such as removing a brain tumor.
“One major advantage of ultrasound is that it makes a number of examinations and operations simpler and less time-consuming, as well as being easier on the patient. For example, in many cases, ultrasound can mean that we don’t need to put the patient under general anesthesia,” says anesthetist Kaj Johansen, who supplied data for the project. He believes that the app is both useful and instructive.
Game-Playing Adds Motivation
Frank Lindseth has many years of experience of using ultrasound. He conceived the idea of an app several years ago, but it turned out to be difficult to get funding for the concept. Now he has developed a beta version with the help of MSc students in computer science at NTNU.
“The feedback we have received from the health personnel who have tested the app has been very positive. They were surprised that it was so much fun in use,” say Hanna Holler Kamperud and Solveig Hellan.
The game has three levels of difficulty, so that new challenges appear as ‘players’ become better at using it. On the first level, they are given all the help they need, but at the highest and most difficult, they work against time.
“This means that there is always room for improvement,” say the students.
Learning to Block the Nerve to a Leg
The app trains the users in the art of identifying the nerve as well as surrounding landmarks in ultrasound images. The task is to place a needle close to the nerve and inject anesthetics around it so that the leg can be operated on.
So far, only a limited amount of illustrative material has been incorporated in the app.
“Our aim is to add more data to the app that will cover more of the anatomical variability seen in patients. When we have done that, the natural next step will be to put the app on-line for downloading,” says Lindseth.
The advantage of using an app for training is that it is always available.
“It is important that it should be used a lot, because the only way to become good at interpreting ultrasonic images is to completely internalize the process. The idea is that you should be able to bring it out in the bus, in a waiting-room or at home on the sofa,” explains Lindseth.
The plan is to put the app on Google Play (Android) and App Store (iOS) and make it available to everybody, as soon as the development team has incorporated a little more data, says the SINTEF scientist.
