Enhances Visualization of the Circulatory and Respiratory Systems, Increasing Diagnostic Accuracy and Facilitating Treatment
This medical imaging device, which distinguishes and characterizes vascular and pulmonary anatomy from surrounding tissue, will aid in the detection and diagnosis of diseases, such as chronic pulmonary arterial hypertension, pulmonary emboli and birth defects (including under developed lungs). Chronic respiratory diseases affect hundreds of millions of people across the globe, according to World Health Organization. More than 500 million people suffer from asthma or chronic obstructive pulmonary diseases (COPD) alone. Available methods for quantitatively characterizing and sizing vessels to identify vascular and pulmonary diseases involve either voxel-based images or thresholding techniques that have poor sizing accuracy. Researchers at University of Florida have developed a medical imaging device that improves the accuracy of blood vessel and airways passage localization and sizing, while also better characterizing the vascular tree structure. The tool uses three-dimensional images of the chest to measure vessel radius, length and location.
ApplicationDevice that uses three-dimensional X-ray computed tomography (CT) of magnetic resonance (MR) images of the chest to identify best-fit centerlines and radiuses of blood vessels and airway passages, and accurate characterization of the vascular tree structure, facilitating vascular and pulmonary disease diagnoses
- Computes a vessel or airway passage’s centerline and radius with greater accuracy than available technology, making the diagnostic process easier
- Characterizes the vascular tree structure with greater accuracy than available technology, improving the delineation of individual vascular trees within the lung versus bronchial circulation
- Provides quantifiable metrics of vessel size to allow calculation of vascular changes that result from disease or intervention, enabling healthcare providers to measure a patient’s response to treatment
- Allows pharmaceutical researchers to better assess drug efficacy, shortening the time from laboratory to market
- Provides new insights into pulmonary diseases, resulting in better clinical decision making
