Intraoperative Ultrasound in Surgery

While pre-operative planning is important, anatomies tend to shift during surgeries, and in some cases may reveal a disparity from what was expected. This is where intraoperative ultrasound serves as a powerful tool to support surgeons in making critical decisions. With precise visualization of blood flows, vascular structures, and targeted regions in real-time, intraoperative ultrasound can accurately guide surgeons through difficult processes, leading to improved surgical outcomes.

 

Minimally Invasive Surgery


Drop-in Robotic Transducer

Select from 2 drop-in probes designed to work seamlessly with the highly sensitive DaVinci robotic arm. The probe's proximal clasping point, small footprint, and flexible cables give surgeons direct control and full Wrist Articulation™ to capture real-time images of organs at complex angles.

 

4-way Flexible Laparoscopic Transducer

With an intuitive push of a button, Hitachi's laparoscopic probe enables 4-way articulation of the tip, giving the required flexibility for imaging organs at all angles. It is useful for localization of tumours, grasping of positional relationship with surrounding vessels, and to search for residual lesions, etc.

Open Abdominal Surgery


Micro-Convex Transducer

Designed by renowned liver surgeon, Professor Masatoshi Makuuchi , this micro-convex transducer can be easily griped between two fingers to allow palpation while scanning. Its small size, combined with advanced imaging modes enables the precise location of resection areas, and detection of new lesions in hepatic and pancreatic surgery.

T-Shape Linear Transducer

For a wider field of view over large areas of the target anatomy, explore T-shape linear probes. This makes it easy to visualize blood flows and interpret the scan plan for accurate resection. It is also useful in post surgical vascularization.







Neurosurgery


Burr-hole Guidance

Introducing the world’s only phased array burr-hole transducer; With exceptional near-to-far field resolution, this probe provides complete visualization into the subcortical space, and supports neurosurgeons with instant feedback for accurate shunt and drainage placements, as well as biopsy guidance.

Craniotomy

Ideal for craniotomies, we have a multi-frequency transducer designed with a footprint of only 20mm. It is compatible with existing pre-operative planning systems to provide exceptional detail for needle guidance.

Spinal Cord

Supporting spinal surgeries, we have a hockey-stick linear array transducer that provides real-time feedback on tumor margin delineation, giving valuable information to guide tumor resections. It can also be used in pediatric cranial surgery when craniotomy is small.







Prostate Biopsy


Transrectal Biopsy

With a field-of-view of 200°, and free choice of imaging planes, Hitachi's end-fire transducers support accurate diagnosis, and systematic transrectal biopsies.

Transperineal Biopsy

Bi-plane Transducers

To better locate the anatomical lesions, our real-time bi-plane transducers supports display the sagittal and axial images of the prostate gland simultaneously. This allows for higher accuracy in biopsy targeting wherein the needles are visible in both cross sections.



Bi-plane Convex Linear Transducers

These side-fire transducers are used for a higher detection rate of high-grade malignancies. It comes compatible with a grid and biopsy template, useful for brachytherapy planning and biopsy guidance.

Colorectal Transducer

Designed with a super thin width of 12mm, the 360° electronic radial transrectal transducer helps assess rectal cancer staging with less patient discomfort.







Abdominal Biopsy


PTBD, PCNL, PCN, Focal Therapy

For suspect lesions located deep in the abdomen, Hitachi's specialized biopsy probes can provide superior real-time guidance to determine the best puncture point and direction for optimal tissue biopsy.


Safer biopsy is made possible as surgeons can visualize needle insertion to the tumour directly under the probe with less bending and minimized dead angles.


Further supported by advanced imaging algorithms like Contrast Harmonic Imaging, and Real-time Virtual Sonography, these transducers support surgeons with all crucial information for surgical success.

eFlow

Provides clearer delineation between tissue and blood flow.
Low velocity flow can also be imaged with high sensitivity.




Carving Imaging

Emphasizes tissue structural edges with high signal to noise ratio for clear visibility of target regions.





Needle Emphasis

Automatically adjusts the image to enhance needle visibility for safer and more accurate punctures.




Contrast Harmonic Imaging

Enhances display of micro-vascular structures for increased precision in lesion characterization, location and also to achieve surgical margin.





Real-time Tissue Elastography (RTE)

Calculates the relative tissue strain and displays its stiffness as a colour map, superimposed on B-mode images in real-time.




Real-time Virtual Sonography (RVS)

Fuses multiple imaging modalities with ultrasound for real-time direct comparison and identification of suspicious lesions.





3D Sim-Navigator

Works with RVS to simulate single or multiple needle paths during navigation to a target. The positional relationship between the marked target and needle paths can be assessed in real time with rotation of the 3D volume, and with additional C-plane orthogonal display to the needle path.





E-field Simulator

From the positioning of multiple electrodes during RFA treatment, we can simulate a distribution of e-field as a colour map superimposed on reconstructed CT/MRI volume data, to determine the optimal arrangement. This flexibility in planning the needle path can bring significant improvement to the treatment technique.







Real-time Needle Tracking

The real-time needle tip location during RFA procedures can be tracked and displayed for higher accuracy and precision. This algorithm also supports the correction of misregistered tip in cases of needle deflection.





Body Motion Tracking

For uninterrupted navigation, the Body Motion Trackers automatically registers the fused images of previously acquired CT volume data sets with real-time ultrasound. It can also be used as a reference sensor during image fusion wherein small patient movements are automatically synchronized and updated.
