Blood vessel sizing device

摘要

Medical devices and methods for determining the size of blood vessels are disclosed. In one implementation, a blood vessel sizing device is configured for placement on an area of skin of a patient. The device includes a plurality of radiopaque concentric-circle elements. In one implementation, a blood vessel sizing method includes placing a marker having a plurality of concentric-circle elements on the skin of a patient, imaging a blood vessel of the patient and the device, and comparing the imaged blood vessel to the imaged circles to determine the blood vessel size, the concentric-circle elements allowing a determination of size without errors of parallax.

主权项

1. A non-transitory computer-readable medium comprising computer-executable instructions that when executed by a processor are configured to perform at least:
receiving data corresponding to a biological feature present in radiological image data; determining a dimensional property of the feature; identifying one or more elements from the image data corresponding to a plurality of radiopaque, concentric-circle elements of a blood vessel sizing device positioned on an area of skin of a patient; identifying a dimensional property for each of the identified one or more elements; determining a longest axis of the identified elements; comparing the determined dimensional property to the identified one or more elements, along the determined longest axis; and converting the determined dimensional property into a true dimension value for communication to a user.
