The MOZART® Specimen Tomosynthesis Imaging System
When the goal is to remove the entire tumor in a single procedure with maximum breast conservation.
Why the MOZART System?
- Creates true 3D images of breast specimens in 1mm slices in a single operation.
- Independently associated with lower re-excision rates (up to 50%) compared to Faxitron 2D imaging.
- More accurate than 2D imaging for identifying positive margins.
- Provides superior visibility through dense breast tissue.
- Reduces the likelihood of excising healthy breast tissue unnecessarily.
- Enables superior cosmesis for the patient.
- Reduces need for time consuming orthogonal views.
3D for larger specimens
The MOZART Supra: 3D imaging for larger specimens.
- The most accurate way to view the anatomy of masteomies, lumpectomies, tissues, and bone.
- Featuring Automagnification – Never touch a mag tray again!
The MOZART ViewAssist™ software package consists of intelligent, specialized features that enable the user to be more efficient.
- Image Blender™ – Combines Optical and X-ray images.
- Voice Control – Uses your voice to control the system.

- Retrospective review of 657 breast-conserving operations performed for cancer from 2013-2018, procedures were performed by four surgeons at a single tertiary institution
- Comparative study of 2D versus 3D image-guided cavity margin excision compared to final pathology and need for additional surgery
- The re‑excision rate for the 2D group was 11% versus 5% for the 3D group
- The use of 3D tomosynthesis specimen radiographs decreased re‑excision rates by more than half
- A lower re‑excision rate is independently associated with 3D tomosynthesis
View for View, 3D Specimen Tomosynthesis Provides More Data Than 2D Specimen Mammography

- Over an 18-month period, 200 patients who had image guided lumpectomies using both intraoperative 2D imaging and intraoperative 3D tomosynthesis were compared
- During the 18 months of adoption of the intraoperative 3D tomosynthesis, there was a significant reduction in re-excision rates, from 16% to 9%
- Use of specimen tomosynthesis in the OR has improved the accurate of intraoperative imagining in 43% of cases
Digital Breast Tomosynthesis for Intraoperative Margin Assessment during Breast-Conserving Surgery

- Study was to determine the ability of digital breast tomosynthesis (DBT) to detect positive margins compared with an institution’s standard extensive processing (SEP)
- This demonstrated the ability of DBT to accurately identify segmental mastectomy specimens having tumor at ink, with a similar sensitivity and higher specificity compared with our institutional SEP
- DBT can replace labor-intensive processing methods given that its rapid acquisition of high resolution, cross-sectioned images of the intact specimen takes approximately 1 min, and can be read by the surgeon
The temporal and financial benefit of intraoperative breast specimen imaging: A pilot study of the Kubtec MOZART
Kornfeld H, Mulder L, Spivey T, Cortina C, Madrigrano A, Kopkash K. Breast J. 2019;25:766-768.
- A retrospective chart review was conducted of all breast cancer patients from Jan 1, 2015 to December 31, 2016 with non-palpable lesions requiring wire- localization for excision
- On average, OR time was 7.6 minutes shorter when using intraoperative imaging as opposed to sending the specimen to diagnostic radiology. This time reduction translates into estimated OR cost savings of $284.62 per case
- This three-dimensional intraoperative imaging allows the surgeon to make a more accurate decision regarding targeted shave margins, which may improve more aesthetics and decrease re-excision rate, which would also provide a financial benefit
Implementation of Intra-Operative Specimen Tomosynthesis and Impact of Re-Excision Rates for Image Guided Partial Mastectomies
Munding E, Woodfin A, Terranella S, O’Donoghue C, O’Hara K, Madrigrano A
- Use of MOZART for localization versus remote radiologic interpretation for determining additional shave margins is associated with lower positive margins rates.
- Use of MOZART was shown to discover positive margins that would have been missed based on final pathology of initial specimen alone.
