First Ring-Shaped Gantry Digital SPECT/CT

360° Total Body 3D Imaging

Spectrum Dynamics Medical built the VERITON with a new generation imaging technology like no other, wrapping 360° around the patient’s body contour for a personalized exam. The heart of the innovation is in a set of 12 digital CZT detectors that automatically move within millimeters of the patient’s body. The 3D hybrid digital scanner gives clinicians comprehensive information to help diagnose with confidence and accuracy.

In the past, converting a dual head camera to more expensive CZT technology without a broader clinical impact offered too little value. That’s why Spectrum Dynamics engineers took the bold step to change the shape of scanning with 360° CZT design, which improves sensitivity to a point that the system can truly affect change. Without the historical dual head design barriers, VERITON delivers proximity and efficiency, resolving complex imaging challenge without the traditional tradeoffs.

VERITON Innovative System Design: 360° CZT

Spectrum Dynamics product portfolio foundation is built on CZT solid-state digital detector technology. The goal is to maximize the benefits of CZT in routine clinical applications in nuclear medicine departments: -consistently generate clinical studies of high image quality; -shorten the scan times; -image using the lowest possible injected activity; -improve diagnostic accuracy; – A digital SPECT/CT such as the VERITON, can help drive new and innovative clinical growth in SPECT imaging with new applications only possible with digital technology, such as 3D dynamic myocardial perfusion imaging.

The engineering and algorithm teams developed four distinctive features for the optimal utilization of CZT detectors for SPECT imaging:

1. CZT columns that swivel to acquire data during acquisition

2. Unique gantry designs to optimize 3D imaging with the digital detectors as close to the organ of interest as possible, key for sensitivity and resolution gains .

3. A comprehensive reconstruction algorithm selection to generate the best image quality possible, with options that until know, were only used in PET/CT imaging for SUV calculation.

4. Integrated acquisition, quantitative reconstruction and review console that allows for workflow efficiency while enhancing the collaboration between the technologist and clinician.

First Ring-Shaped Gantry Digital SPECT/CT

Transition to Routine 3D Imaging with Next Generation SPECT imaging Technology

Because the digital detectors snugly surround the patient to
sense maximum photons, the 3D image quality reveals more
detail than planar, Anger based images. The multipurpose SPECT/CT system scans from head to toes in NM/CT hybrid mode, maximizing routine clinical utilization and providing detailed information in a single 3D scan. Avoid the need to request extra views—easier on the patient.

Total body SPECT/CT workflow, with 2m continuous coverage
during a hybrid acquisition, allows for efficiency and additional information when compared to a planar whole-body scan, plus an additional, localized SPECT/CT scan. The final 3D images are corrected for scatter and attenuation, partial volume effect and can be used to generate multi-view planar
(MVP) images, if required.

Improved lesion detection could be just the start. One total body acquisition result in a 3D view with PET-like slices,
shortening exam times, and the imaging efficiency allows a
lower injected dose. Those operational changes can transform the way imaging is scheduled and carried out.

Choice of 16/64 Slice Diagnostic CT Capabilities for VERITON-CT

Clinicians can use the high-resolution, low-dose CT scan data, not only for attenuation correction and localization, but also to routinely reconstruct SPECT data with partial volume correction (PVC) for improved contrast and resolution. CT image quality tools, such as metal artifact reduction, LISA low-dose iterative reconstruction and 4D dose modulation, are standard features of the VERITON-CT configuration to meet the needs of demanding nuclear medicine and radiology departments.

VERITON-CT Image Generation: A first in SPECT/CT

Console allows for true multi-tasking: acquisition, reconstruction, and quantitative post processing of the 3D data. Image tool kit includes advanced reconstruction algorithms to ensure quantitative accuracy.

The VERITON and VERITON-CT systems are equipped with
advanced image processing algorithms to ensure state-of-the-art image quality. Options include OSEM iterative reconstruction with resolution recovery, attenuation correction (AC), scatter correction (SC), partial volume correction (PVC), high energy correction (HEC) and more.

As hybrid SPECT/CT systems increasingly become the standard
of care around the globe, maximizing the use of the CT
beyond anatomical localization, attenuation correction, or
even basic diagnostic imaging becomes more relevant. Low
dose CT scan data can also be used for Partial Volume
Correction of the reconstructed image. The aim of PVC is to
transfer the sharp edges provided by the CT into the SPECT
image by constraining the activity to remain within the
anatomical region edges during the reconstruction process

“The Nuclear Medicine Department has two gamma cameras and performs around 4,500 examinations a year. We are replacing the older gamma camera with a VERITON-CT system, as we feel this is the best on the market. We want to use the increased quality of imaging and speed of scanning to improve our clinical outcomes and patient experience.”
Dr Stewart Redman - Consultant Radiologist

The VERITON-CT Solid State Gamma Camera has an intelligent novel design which permits focused collimation. The use of CZT crystal detectors means the system sensitivity is a lot higher than existing PMT designs, but also has the major advantage of better energy resolution which result in improved contrast and resolution. The higher sensitivity facilitates much faster scans, improving patient experience and allowing an increased patient throughput. The team recognizes the real potential the VERITON-CT has over other systems and looks forward to working with Spectrum Dynamics to develop new and exciting imaging techniques.” Dr. Martyn Evans - Consultant Medical Physicist, The Royal United Hospital RUH Bath

“I personally think the VERITON-CT® is the most exciting breakthrough camera for nuclear imaging since Hal Anger developed the conventional gamma camera in the 50s. The possibility of three-dimensional full-body studies, reduced injected dose to patients, reduced scan times and smart workflows, give a clear advantage over traditional gamma cameras and open a new door to the future of nuclear medicine imaging.”
Veronica Sanchez
Head of Nuclear Medicine Section - from Linköping University Hospital - Sweden
“The VERITON-CT is a huge leap forward for nuclear medicine both in terms of the digital CZT detectors and the 360-degree capability. We’re excited by the possibility of increased sensitivity, improved workflow and reduced doses, as well as the potential of new applications of dynamic 3D SPECT. We are thrilled that our patients in Bath will be the first in the UK to benefit from this exciting new technology.”

"In recent months, the nuclear medicine department at the St Vincent Clinic in Besançon is now performing 14 myocardial perfusion SPECT studies daily due to the 60% reduction in acquisition time in both stress and rest. At the same time, the image quality of the VERITON®- CT is significantly higher than our conventional camera (commissioned in 2019). We have reduced doses by 20%. We plan to start coronary reserve calculation studies in 2021. Dynamic imaging capabilities, with the improved spatial and temporal resolution will make this possible. With regard to DATSCAN studies, we now perform examinations 15% faster, with 33% dose reduction. We did not change the doses for the lung scans coupled with the CT scan with quantification, but the acquisition time was reduced by 25% with increased resolution. Finally, thyroid acquisitions combining tomoscintigraphy and reconstructed planar images are currently being validated similar to that of conventional planar scintigraphies."

"VERITON-CT constitutes a significant technological leap …and we are only at the beginning of exploiting its possibilities"
