SOFIA for Whole Breast Imaging
3D Breast Ultrasound in Seconds
The new SOFIA 3D breast ultrasound system solves all the economic and logistic challenges associated with whole-breast ultrasound by using a full-field radial scanning method. The resulting throughput, efficiency, and patient comfort make SOFIA the ideal solution for women with dense breasts.
The 30-second Whole-breast Scan
SOFIA scans an entire breast in a single 30-second radial sweep, allowing SOFIA users to see more patients per day. The data for each breast is then sent to the radiology workstation as a single 3D volume where SOFIA’s powerful review tools enable shortened interpretation times.
SOFIA does not require a dedicated room for whole-breast ultrasound. Its convertible scan table and Hitachi Healthcare scan engine allow you to use SOFIA for a wide variety of diagnostic ultrasound exams when it is not being used for whole-breast imaging. Unlike other automated breast ultrasound systems, it requires no additional consumables and no time-consuming pre-scan preparation.
SOFIA was designed to reduce patient anxiety by providing the most comfortable and private exam possible. SOFIA exams are done in the prone position, allowing the patient to rest comfortably and remain completely covered during the short scan.

Because the SOFIA is powered by the Hitachi ARIETTA 70 premium ultrasound system, it comes equipped with a host of powerful imaging capabilities.
Whether its source is a world class orchestra or advanced medical equipment, recording sound is an art form. It requires precision instrumentation to capture the most subtle details without introducing noise in the process. Arietta 70’s Symphonic Technology optimizes data fidelity along the entire signal handling chain, from transducer to display monitor.
- Multi-layered Crystal - Using multiple layers of crystal within each element, Hitachi Healthcare’s probes minimize signal attenuation during transmit and receive to increase penetration.
- Compound Pulse Wave Generator - CPWG+ is a unique transmission technology that allows Arietta 70 to generate pulses to the ideal theoretical waveform. As a result, the heat generation during electro-acoustical conversion is minimized. This allows the use of stronger pulses to improve penetration, contrast and spatial resolution, and signal-to-noise ratio.
- Pixel Focusing - Arietta 70 dynamically focuses at the pixel level improving resolution and image uniformity.
- Ultra Backend - The high-speed digital computing of the Ultra Backend fuels the various real-time image processing features of Arietta 70 of frame rate.
- IPS-Pro Display Monitor - Developed initially by Hitachi Displays, Ltd., In-Plane Switching (IPS) was the first LCD technology to improve viewing-angle. The Arietta 70’s IPS-Pro display doubles the half-contrast viewing angle of these displays while also improving contrast, black levels, and switching speed.
Real-time Tissue Elastography1
SOFIA supports Hitachi’s third-generation hand-held elastography imaging using one of the many supported high-frequency linear probes.

3D Visualization Tools
Efficient, High-speed Interpretation
SOFIA’s workstation delivers images in planes just like those acquired in hand-held ultrasound exams but with fields-of-view that are considerably larger than conventional images. As a result, doctors can quickly survey all the full-field slices comprising the total volume with average interpretation times of approximately 1 minute per breast.
The efficiency and speed that characterizes SOFIA during scanning continues in interpretation. Because each breast is presented to the radiologist as a single, high resolution DICOM-compatible dataset and interpreted in familiar planes, review times are greatly shortened.
One Volume Data-set Per Breast
SOFIA presents the entire breast in a single volume study; interpreting fewer volumes per patient means shorter read times.
Review in the Natively-acquired Plane
Images can be reviewed in the same plane as they were acquired, reducing interpolation and volume averaging from out-of-plane reconstruction and maximizing spatial resolution.
Comprehensive 3D Review Tools
When suspicious areas are found, the data-rich volume and comprehensive image 3D review tools allow physicians to further characterize any mass or structure without calling back the patient.
The multi-planar reconstruction allows the simultaneous visualization of any mass or structure from multiple planes
Any breast imaging is always accompanied by a level of patient anxiety; SOFIA was designed to reduce this through its comfortable and private exam experience.
- Scanning in the prone position means that patients can remain covered during the entire exam
- Because the patient’s own body weight provides enough compression, the external compression methods required in other whole-breast systems are unnecessary
- SOFIA scans require only a thin layer of acoustic coupling lotion that can be rubbed into the skin after the exam
- The elegant curves and multi-layer memory foam design of SOFIA make it both inviting and comfortable for the patient
Conventional wisdom says that implementing a whole-breast ultrasound program can be a costly and time-consuming proposition. SOFIA defies this by delivering a solution that provides the speed of automation without requiring a dedicated room. With its convertible scan table and the premium-class ARIETTA ultrasound system powering its imaging, the SOFIA room can be used for diagnostic breast scanning, biopsy or any other number of applications when not enlisted for whole-breast scanning.
- SOFIA is compatible with multiple high-frequency linear probes for hand-held diagnostic breast scanning
- In a general imaging environment, SOFIA can be paired with any of its dozens* of compatible probes and used as a conventional scan bed
* Exact number of compatible probes varies according to the Hitachi ultrasound system paired with SOFIA
By entirely re-imagining how breast ultrasound is performed, SOFIA is able to perform bilateral breast ultrasound scans in an exam that rivals any modality in the breast imaging suite in terms of speed and comfort. The key is SOFIA’s unique scanning cone, which is recessed into its comfortable scan bed and houses Hitachi’s extra-long linear probe. The patient lies in the prone position placing her breast with the nipple in the center. In just a single 30-second radial sweep, a 3D volume dataset is collected of the entire breast.
- 30-second scan time per breast allows the scheduling of patients as often as every ten minutes
- Automated and reproducible
- Requires only a thin layer of ultrasound lotion—no additional disposables required
- Intuitive touch-screen interface automates the entire process
