How can the examination workflow in sonography be changed in such a way, that doctors are able to focus more on their patients?

How can I adapt the examination workflow of physicians so that they can focus more on their patients needs?

Often patients cannot get themselves into the required examination position. The wireless probe releases the doctor's second hand. The free second hand allows an intuitive positioning of physically weakened and overweight patients. This freedom allows physicians to take reliable, high-quality ultrasound images, even from hard-to-reach places.

The probe's wristband functions as an interface between the physician and the ultrasound device. All main functions required for the examination are located there and are easy to reach.

1. The sonographer unplugs the cable; the wireless ultrasound examination is starting.

2. The second hand is free and the sonographer is able to focus the patient completely.

3. The wristband allows the sonographer to interact with the ultrasonic unit.

4. It is easy to change the patients position.

5. The sonographer focuses completely on the patient.

6. This enables intuitive touching and feeling.

Sonography, as a non-invasive real-time imaging method, has become an integral part of medicine. In the future, in which medicine is increasingly associated with prevention, it offers great potential. This project requires an examination of two perspectives. On the one hand, sonography experts who interpret ultrasound images. But it also addresses patients who are often physically unable to meet the requirements of the ultrasound context.

User Research


At the Albertinen Hospital in Hamburg I accompanied specialists for two days. The focus was on abdominal sonography.

By observing everyday work processes I was able to gain numerous insights. I recognized valuable information through watching and talking to sonographers and their patients.

During a visit at the ultrasonic showroom of Siemens Healthcare I was able to try out various devices myself. Experts explained the handling of ultrasound devices.

User Journey


The User Journey summarizes all collected insights.


Insight 01

During the examination situation there is a basic position for examiners. One hand is permanently on the keyboard to control the device. The other hand guides the ultrasound probe over the patient.

Quote from a doctor: "As you can see, here you are always 'playing the piano' with one hand."

How might we enable the doctor to focus his workflow on the patient?


Insight 02

The cable of the ultrasonic probe is a hygienic and ergonomic problem.

The examiners use relieving postures to avoid these problems.

How can we minimize ergonomic impairments?

Ideation Workshop


In a workshop with students and designers from Siemens (Healthcare) Healthinieers, we translated the first insights into first ideas and prototypes.


Prototyping first ideas.


How is it today. What might be desirable tomorrow?


By building prototypes and making first ideas quickly experienceable, I was able to gather further insights during the process.

Insight 03

The determination of clear ultrasound images is essential for reliable diagnostics. For that high-quality images from different perspectives, patients often have to lie in different positions. It is often difficult to obtain clear ultrasound images because many patients are obese. Also old and weak patients are physically unable to do this.

How might we facilitate the doctor's work with physically weakened or obese patients?

Iteration trough Prototyping

The examiner should be able to interact freely without being bound to a basic position or the probe cable. The doctor should be able to help weak patients to move into the required position.


What if the sonographer could use the second hand to feel the right position for the probe.
