摘要:
During a focused-ultrasound or other non-invasive treatment procedure, the motion of the treatment target or other object(s) of interest can be tracked in real time based on the comparison of treatment images against a reference library of images that have been acquired prior to treatment for the anticipated range of motion and have been processed to identify the location of the target or other object(s) therein.
摘要:
An image-guide therapy system comprises a thermal treatment device (e.g., an ultrasound transducer) configured for transmitting a therapeutic energy beam, and The system further comprises an imaging device (e.g., a magnetic resonant imaging (MRI) device) configured for acquiring images of the target tissue mass and the thermal treatment device. The system further comprises a controller configured for controlling thermal dose properties of the thermal treatment device to focus the energy beam on a target tissue mass located in an internal body region of a patient, and a processor configured for tracking respective positions of the thermal treatment device and the target tissue mass in a common coordinate system based on the acquired images. The system may optionally comprise a display configured for displaying the acquired images.
摘要:
A method for transcostal ultrasound treatment of tissues includes determining rib locations, e.g., based on ultrasound reflections off the ribs or acoustic radiation force signals, and transcostally focusing ultrasound into the tissue while minimizing damage to the ribs.
摘要:
Images acquired during an image-guided treatment procedure sometimes exceed the scope of a reference library previously acquired for the purpose of monitoring and/or adjusting the treatment. In this situation, the reference library may be extended dynamically and/or in real time based on the newly acquired treatment images and/or other available information.

摘要:
A method for spatially localizing a rib cage prior to transcostal ultrasound treatment of visceral tissue includes computationally refining a three-dimensional model of the rib cage based on image slices taken at multiple locations along the ribs with orientations dependent on local rib orientations.
