Radiation risks for children using Cone Beam CT in the dental office

Radiation risks from Cone Beam CT
1

An interesting article published today by The New York Times citing usage of Cone Beam CT especially by orthodontists and the worries for radiation risks for children who are more susceptible to radiation.


The article also goes over “lazy” dentists who still prefer to use D-Speed film over F-Speed mistakenly thinking it is superior at the expense of 60% more radiation. This however seems to affect the US more than other parts of the world.

NVIDIA video cards to help lower Cone Beam CT radiation

Current Cone Beam CT reconstruction algorithms use the processor (CPU) to process the acquired data to generate an image. Graphics processors like NVIDIA Tesla can also process data but at 10-100 times faster than computer processors; however, programming for graphics processors is much harder and only recently it was made possible thanks to technologies from NVIDIA to help programmers do that.


Researchers from the University of California at San Diego were able reduce the amount of radiation to patients by ten folds or more thanks to a new approach for processing x-rays.


Cone Beam CT is not only used for scanning patients but also is used in image-guided radiation therapy (IGRP). Reducing total number of projections, mAs level per projection during a CT scan reduces the total radiation dose delivered to the patient. However, this results often in a noisy and mathematically incomplete data that takes hours to process through iterative processing via the computer’s processor. Because the Cone Beam is used for treatment, fast reconstruction is needed, explains the lead author Xun Jia, who is a post doctoral fellow at UCSD. Continue reading →

ImageWorks closes agreement with Sleep Group Solutions for NewTom VGi Flex in mobile Cone Beam units within US and Canada

Sleep Group Solutions (SGS) today announced an agreement with ImageWorks whereby SGS will distribute and promote the NewTom VGi Flex mobile units for Sleep Disorders in the US and Canada. SGS is a leading provider of airway diagnostic technology which serves the needs of physicians and dentists interested in screening, diagnosing and treating sleep apnea and other upper airway disorders.


The NewTom VGi Flex is the only 3D Cone Beam CT system which carries a warranty for installation in mobile environments. Treatment of dental sleep disorders is becoming one of the most added procedures to the dental office. Having a patient treated for dental sleep disorder and providing a NewTom VGi 3D Cone Beam CT scan, the patient can expect a more accurate airway assessment and a quicker and more effective treatment plan.

Dental intraoral digital impression systems like CEREC AC , Lava C.O.S , and iTero allow the practitioner to take digital impression of the patient’s teeth and store them in the computer. The practitioner then can use the software to design and fabricate crowns, veneers, onlays and inlays either by sending the data to the lab or the milling machine in the office for on-site fabrication.


Cone Beam CT allows 3 dimensional imaging of the patient’s head and it stores the acquired data  in a volumetric data set. There is no superimposition of anatomical structures and no magnification. Volumetric data set from the Cone Beam CT can be visualized in different ways like MPR slices, volume render, synthetic panoramic, or surface render. Cone Beam CT can be used to aid in diagnosis and treatment planning. Continue reading →

Suni Medical systems has introduced a small field of view CBCT for use in dental and endodontics. Debuted as Suni3D HD, the new CBCT can do 5×5 or 8×5 cm FOV at 0.08 mm voxel size. It should provide high-resolution images 3D images for teeth and surrounding structures.


“Suni has always been interested in the specialized needs of endodontists,” said Paul Tucker, vice president of marketing.


“The small field of view design is perfect for quadrant dentistry, while keeping radiation doses for patients at a minimum,” said Tucker. “The Suni3D HD system is one of the few systems on the market with a 5×5-cm focused field of view meaning lower doses of radiation for the patient and less liability for the doctor.” Continue reading →

Cone Beam CT is widely used today for dental and maxillofacial diagnosis and treatment planning. CBCT installation bases are now taking a new trend in dentistry beyond imaging centers, dental schools, mobile CBCT and private practice. Dental labs are now investing into CBCT to have scan done at their lab while providing lab work to their clients. CBCT is used mainly nowadays for implant placements as it provides a 3D view for the patient head and mouth. By using Cone Beam CT,  clinicians can have a better view for patient’s teeth, bone and jaws and  it is possible to determine if the patient is suitable to have implants placed immediately or whether a bone graft might be need; thus lowering the risk for complications or implant failure.
