Attachments: Lung scans depicting healthy/control subjects and lungs of a Veteran with biopsy confirmed constrictive bronchiolitis as processed by 4DMedical XV LVAS Software. Single slices of 4DMedical XV scans from the Vanderbilt ‘burn pit’ clinical trial (left) from a healthy/control subject and (right) from a veteran exposed to burn pits with biopsy confirmed constrictive bronchiolitis. The image on the left visualizes principally as green representing average levels of ventilation, while the image on the right shows significant regions of both red (low) and blue (high) ventilation. In addition to the visualizations shown here, additional quantitative scores and assessments identify the differences between veterans with constrictive bronchiolitis and healthy controls.
November 21, 2022 — Radiological Society of North America (RSNA) 2022 meeting attendees are invited to visit 4DMedical’s conference booth #2768 to see 4DMedical, a Woodland Hills, Calif. - based medical technology company and creator of the world’s most advanced medical imaging technology. 4DMedical will be unveiling its XV Scanner, the world’s first dedicated lung scanner, at RSNA.
The XV scanner, which integrates 4DMedical’s XV Technology, represents a significant step forward in lung diagnostics. The new imaging tool allows physicians to detect areas of high and low ventilation with pinpoint accuracy across all parts of the lung, in all phases of the breath. The resulting ventilation report is extremely clear and easily understood by providing clinicians with a color-coded and dynamic visualization of the patient’s breathing lung, enhanced with four-dimensional animation. For the first time ever, it enables highly detailed maps of pulmonary function to be created from a scan captured in 5 seconds using less radiation than a typical chest x-ray.
The XV Technology software automatically analyzes and applies its proprietary algorithms to identify and quantify regional functional impairment in both lungs. The resulting report numerically quantifies and graphically displays the regional impairments, which can then be used by clinicians to better understand the patient’s current functional state and assess the most effective therapeutic action.
4DMedical’s XV Technology is a cloud subscription service that can be implemented immediately with no capital expenditure by using existing hospital and clinical infrastructure. Imaging departments electronically transmit radiographic images collected with existing X-ray fluoroscopy equipment to 4DMedical.
Vanderbilt University is an example of an institution using the XV Technology software with its existing imaging substructure to research Deployment Related Respiratory Disease (DRRD) in US veterans exposed to burn pits.
