Biopsies for a differential diagnosis of cancer, pain management therapies for patients suffering from back pain, or drainage placements. These are just some procedures that are commonly performed under CT guidance,1,2,3 especially when the access path requires cross-sectional image guidance.4 Whether you’re using an advanced or basic CT scanner, it is your goal to optimally handle CT-guided interventional procedures. For this, you need a comprehensive and modular solution that reliably supports you, simplifies workflows, and maximizes safety.

CT-guided interventional procedures on the SOMATOM go.platform
Enhancing speed, precision, and flexibility
Features & Benefits
Safeguard your workflow with operational efficiency
CT-guided interventions are critical. Efficiency and a streamlined workflow matter during these minimally invasive procedures. Discover our interventional portfolio for the SOMATOM go.platform.
myNeedle Companion
myNeedle Companion is the first solution from Siemens Healthineers that harmonizes needle procedures across modalities. It helps simplify even complex image-guided needle procedures with targeted needle path planning and guidance, 3D image registration, and fusion display.
In-room control
myNeedle Companion offers dedicated in-room control that allow you to work as you prefer and help reduce miscommunication – thus, boosting workflow efficiency.
The patient-side system control includes:
- In-room tablet5 with touch user interface provides direct and intuitive software access – to easily zoom, pan, change window settings, and adjust scan parameters
- i-joystick enables freely moving the patient table to any position or to return it to a dedicated position – for instance, the last scan position or the position of the currently selected axial image
- Footswitch enables triggering radiation for easy scanning
Powerful technology for consistent results
Powerful technologies support accuracy and safety to prevent complications during targeted needle placement. Learn more about our solutions.
myNeedle Guide 3D
01
HandCARE™ is only available with i-Fluoro
CT-guided procedures with dose modulation
Dose matters in CT-guided interventions for both patient and operator. HandCARE™ enables real-time dose modulation during CT-guided intervention procedures and prevents direct radiation exposure to the clinician’s hand – by switching off the X-ray exposure for a 100° angle between three possible user positions:
- 10 o’clock
- 12 o’clock
- 2 o’clock

Planning & visual guidance with
myNeedle Guide 3D
myNeedle Guide 3D6 simplifies workflows for both routine and complex CT-guided interventions. You can easily plan multiple needle pathways in different cross sections. Both, path planning and visually guided insertion of multiple needles are supported within the workflow. Integrated Image Fusion allows fusing of 3D images from different modalities or contrast-enhanced prior CT studies to accurately plan needle paths around critical anatomy.

Monitoring needle progression with
i-scan modes
Three powerful i-scan modes provide high flexibility when monitoring the needle progression:
1: FAST i-Sequence
A dose-conscious step-and-shoot mode that enables quick scan repetitions for dynamic monitoring of targeted needle placement, acquires three slices per scan, or enables 3D guidance by covering 100% of the detector width6.

Monitoring needle progression with
i-scan modes
Three powerful i-scan modes provide high flexibility when monitoring the needle progression:
2: i-Spiral mode
Offering flexible volume coverage for 3D guidance, the i-Spiral mode6 makes you independent of the detector width – thus enabling full organ coverage if necessary.

Monitoring needle progression with
i-scan modes
Three powerful i-scan modes provide high flexibility when monitoring the needle progression:
3: i-Fluoro
This mode has been designed for fast and precise needle placement, even in most complex and moving anatomies. It also continuously delivers real-time imaging with up to 10 frames/s to support you in hitting the target in one path.

Artifact reduction with iMAR
Artifacts due to metal implants or the device used in interventional procedures (e.g., RF ablation) often hamper image quality. iMAR is a special reconstruction algorithm that helps reduce metal artifacts for better image quality without increasing dose – supporting precise needle positioning in areas adjacent to metal implants.

Secure your investment with modular solutions
Whether in small or midsize hospitals or independent imaging centers: Biopsies, drainages, and pain therapy have become routine procedures.7 Thus, offering them has become essential in order to stay competitive.
myNeedle Companion is universally available on the SOMATOM go.platform. It is a flexible and modular solution. Depending on your procedure mix, you can choose between these options that to best support your procedure mix:
- 2D guidance with myNeedle Guide 2D to support in-plane procedure.
- 3D guidance with myNeedle Guide 3D6 to support in-plane as well as double-angulated procedures.
- Both can be enhanced with i-Fluoro for real-time imaging where needed.
