Horos is also making an impact in cardiology and general surgery. Surgeons have used its 3D MPR and Volume Rendering capabilities to create . This allows surgical teams to hold physical, patient-specific models of complex structures like the heart before ever making an incision, leading to improved surgical planning and outcomes.

Human medical imaging software is often cost-prohibitive for veterinary practices. Horos is widely used by veterinarians to view CT and MRI scans of animals—requiring only a Mac computer. horos software

OsiriX has evolved into a paid, FDA-approved medical device with a 64-bit version for clinical diagnostic use in the United States.
