Carestream takes orders for new OnSight 3D Extremity System


Carestream is taking orders from healthcare providers worldwide and was due to begin shipping its OnSight 3D Extremity System in December.

The OnSight 3D Extremity System uses cone beam CT (CBCT) technology to capture weight-bearing and other types of extremity exams.

Helen Titus, Carestream’s Worldwide Marketing Director for Ultrasound & CT Solutions, said: “The compact system provides high-quality, lower-dose 3D imaging studies. This makes it an ideal diagnostic tool for orthopaedic and sports medicine practices, hospitals, imaging centres, urgent care facilities and other healthcare providers.”

It’s designed to provide high quality 3D images at the point of care – with easy open bore and patient access to allow weight-bearing studies not possible with traditional CT.

Site and install requirements are low to enable a fast, affordable, convenient imaging process for timely diagnosis and commencement of treatment.

“Orthopaedic imaging is a major focus for Carestream because of the prevalence of musculoskeletal conditions among people of all ages. Youth and adults often suffer sports-related injuries to their knees, ankles and feet while older adults experience arthritis, joint instability, meniscus loss and other conditions,” Titus explained.

The new extremity imaging systemcan help with diagnosis and treatment for orthopaedic conditions that affect the biomechanical behaviour of the joints such as arthritis, meniscus loss, instability and malalignment syndromes.

The CT system enables healthcare providers to capture high-quality 3D images and conduct a patient consultationin a single visit, which helps improve productivity and convenience for both specialists and patients. An additional benefit is the ability for patients to view a 3D image that illustrates their condition or injury to help them understand the reason for a treatment or surgical procedure.

  • Easy interoperability in a DICOM supported environment


Philips launches world’s first detector-based spectral CT scanner


Philips Healthcare launched their IQon Spectral CT in Canada in November. The IQon Spectral CT is the world’s first and only spectral detector CT, designed specifically for spectral imaging. It delivers on-demand colour quantification and the ability to characterize structures simply and at a low dose.

The IQon Spectral CT provides multiple layers of retrospective, diagnostic data in a single, low-dose scan with seamless integration into existing hospital system protocols. It can provide sufficient information with only one scan to help clinicians make fast, confident diagnoses, driving improved clinical and economic outcomes, said Philips in press statement.

The IQon Spectral CT adds spectral resolution to traditional CT scanning through a new dual-layer spectral detector. It identifies photons of high energy and low energy simultaneously, allowing not only the view of anatomy, but also uses colour to characterize the material content of critical structures.

“The Philips IQon Spectral CT is further proof of our commitment of delivering meaningful innovation,” said Iain Burns, President and CEO, Philips Canada. “Today’s patient-centred healthcare environment requires the ability to enable ‘first-time’ right testing and diagnostics. With just one scan, the new IQon SpectralCT can provide clinicians with the information required to help them make confident diagnoses quickly.’’

Spectral Diagnostic Suite
Philips’s has developed the Spectral Diagnostic Suite (SpDS) – a set of advanced visualization and analysis tools designed for the IQon Spectral CT to deliver enhanced spectral viewing and advanced clinical applications capabilities.

By providing spectral capabilities within traditional CT applications, SpDS offers a new level of flexibility and clinical information for CT users, allowing clinicians to utilize the spectral information “on-demand”, to achieve better clinical decision support withoutany added complexity of special modes or workstations that disrupt user workflow.

Additionally, because there is no need to bring the patient back for additional imaging, on-demand spectral analysis of a particular region allows the physician to further analyze incidental findings and at the same time reduce dose exposure to the patient.

Dr Prabhakar Rajiah, MBBS, M.D., FRCR, Assistant Professor of Radiology, University Hospitals of Cleveland, UH Case Medical Center, Department of Radiology, who collaborated with Philips on the development of the suite, said the Spectral suite “offers a new level of control for clinicians, allowing for segmentation on different energy levels, more detailed comparison between images, and advanced fusion capabilities, for diagnostic confidence”.

The Philips SpDS package includes:

• Spectral enhanced Comprehensive Cardiac Analysis (sCCA)
• Spectral enhanced Advanced Vessel Analysis (sAVA)
• Spectral enhanced Tumor Tracking (sTT).

The Philips SpDS also allows for viewing and analysis of spectral datasets in a variety of settings: a reading room, on picture archiving and communication systems (PACS), or from remote locations.


GE adds to Revolution CT family

GE Healthcare continues to invest in the Revolution family of CT systems with innovations that help clinicians redefine what’s possible with CT.

GE says each product in the Revolution family is designed to deliver four key benefits: diagnostic confidence, patient care, financial performance and clinical excellence.

At the 2016 annual meeting of the Radiological Society of North America (RSNA 2016), GE Healthcare launched the Revolution CT scanner with Whisper Drive technology. The CT scanner is designed to take high-speed scans that allow full imaging of the heart in just one heartbeat.

Full imaging of the heart in one heartbeat is accomplished via a high-speed X-ray tube that reaches 70 Gs as it spins around the patient lying inside the scanner’s gantry up to five times per second. This high speed, combined with intelligent motion correction, allows doctors to image the heart in just one heartbeat.

Revolution CT generates 512 slices, allowing easier imaging of moving parts like the heart.

Also at RSNA – the largest radiological exhibition in the world – GE introduced their Revolution CT with Gemstone Spectral Imaging (GSI) Xtream.

GE says the Revolution CT with GSI Xtream provides “uncompromised image quality and clinical capabilities across all clinical areas through the convergence of whole organ coverage, speed, image quality and spectral imaging all in one CT system”. The Revolution CT with GSI Xtream features Smart Technologies and comprehensive stroke and trauma capabilities focused on key clinical outcomes.

The company says GSI is unique in its ability to optimize contrast volumes, reduce beam hardening from dense objects such as metal and perform material characterization. GE notes that the GSI feature is 510(k) pending at US FDA. It is not CE marked and is not available for sale in all regions.

At RSNA GE announced two key technologies to help providers with standardization of protocols across multiple CTs and locations – Imaging Protocol Manager and Dose-Optimized CT Protocols. Imaging Protocol Manager is a cloud-based protocol management solution that reduces the time that protocol teams spend in developing, distributing and monitoring protocols for CT, MI, MR and X-ray devices, helping them deliver the right exam for each patient, every time by leveraging the GE Health Cloud to provide access, insight, and governance for GE and eventually other devices.
