At MWU Medical Software we create applications for simulations and education in the field of prenatal ultrasonography. We develop computer programs, visualizations in virtual and augmented reality as well as mobile applications. Our projects are being created by Holobits company as a result of long-standing experience in software development and by experts in OB/GYN who are primarily focused on diagnostic ultrasonography. For many years our physicians have been offering prenatal ultrasound and counseling to the best obstetricians in Cracow and their patients at MWU DOBRE USG Diagnostic Center and through MWU Workshops (Małopolskie Warsztaty Ultrasonografii) they have been providing extensive didactic support aimed at obstetricians and gynecologists from Poland and abroad.

MWU Medical Software platform was also based on a collection of 3D Fetal Heart models, including 28 Congenital Heart Defects. These 3D models were created by three-dimensional ultrasound acquisitions of fetal hearts for over a decade as well as by cooperating with a team of industrial designers. Our models have been utilized by many experts all over the world, who utilise them for educational purposes and when dealing with pregnant patients diagnosed with Congenital Heart Disease in the fetus..

Fetal heart models presenting Congenital Cardiac Disease were developed in 3D printing technology and “brought to life” in Virtual Reality, which gave rise to our first mobile application – Fetal Heart VR.


Watch the coverage of Fetal Heart VR prototype launch, which took place during Advanced Fetal Cardio course on 7th December 2018. The premiere of version 2 is planned for March 2021.

Our team consists of specialists in various fields:

  • medicine – physicians focused on prenatal and pelvic ultrasonund, consultants in OB/GYN, who provide substantive framework for our projects;
  • physics, computer science and graphics – designers and programmers responsible for developing our applications;
  • industrial design – engineers specializing in product design develop and implement 3D fetal heart models, which are an invaluable educational tool for doctors and patients, as well as lay the foundations for Fetal Heart VR application.


  • to improve global detection rate for Congenital Heart Disease (CHD) in the fetus through:
    1. disseminating knowledge among examiners about sonographic prenatal cardiac evaluation, both normal and abnormal;
    2. teaching by comparing and emphasizing morphological and geometric differences between normal and abnormal fetal heart images;
    3. applying innovative educational solutions, such as synthetic teaching aids, creating tangible and electronic didactic resources based on novel technologies, e.g. 3D printing, virtual reality (VR), augmented reality (AR) in order to achieve the above-mentioned goals;
  • promoting professional ultrasonography by means of cutting-edge educational programs;
  • creating educational models dedicated for medical specialties which require hands-on practice and associative learning.
