ULTRASONIC VOLUME FLOW MEASUREMENT FOR ABLATION THERAPY

摘要

A method for ablation treatment using ultrasound data begins by identifying pathology to be treated and one or more blood vessels proximate the treatment site in a medical diagnostic image. The identified ROI and the blood vessels are automatically indicated in an ultrasound image Ultrasonic Doppler velocity data is acquired from the flow within the vessels and the Doppler data is used to calculate the volume blood flow through the vessels. The thermal effect of the heat transported by this blood flow is considered in the planning or conduct of the ablation treatment, as by modifying the size of a burn zone graphic around the tip of the ablation probe.

1. A method for using ultrasonic information for ablation treatment of pathology comprising:
acquiring a treatment planning image of pathology to be treated by ablation and one or more blood vessels in proximity to the pathology; identifying pathology to be treated by ablation in an ultrasound image; identifying one or more blood vessels that are in close proximity to the pathology by placing a surface shape at a region of interest in the ultrasound image; acquiring three dimensional ultrasound Doppler data from the blood flow of the identified blood vessels by acquiring ultrasound Doppler data at an intersection of flow of the one or more blood vessels with the surface shape; calculating the amount of blood flowing through the identified blood vessels using the ultrasound Doppler data; and developing an ablation treatment plan that considers a heat transport characteristic of the amount of blood flowing through the identified blood vessels, wherein placing the surface shape is performed automatically using knowledge of the location of the blood vessels obtained by registration of the ultrasound image with the treatment planning image.
