摘要:
This invention pertains a system and methods for ablation treatment of tissues. The invention aims to aid healthcare professionals in completely treating all the target tissues by fusing computer generated information highlighting which tissues have been treated and which not to images of the tissues. The systems and methods integrate seamlessly with current image-guided procedures and do not require tracking systems to gather the position of the ablation device, as the positon and orientation of the device are identified from images. The invention aims also to improve estimates of the ablation volumes associated to an ablation device by identifying from images the true geometry of devices that might deform during the deployment in tissues; the invention aims to improve estimates of the ablation volumes by using information about the ablation process and about the status of tissues which can be collected from the control system of the ablation device.
摘要:
A probe sensor has a printed circuit comprising a coplanar transmission line, a ground plane, a plated-through contact via, and a part-circular ring of ground vias surrounding the contact via. The coplanar transmission line and ground plane are formed on a first layer of the printed circuit, and the contact via and part-circular ring of ground vias are plated with a conductive biocompatible material on a second layer of the printed circuit. A system uses a network analyzer with the probe to measure electrical properties of biological tissue. Also described is a method of using the system to determine qualities of stored blood.

摘要:
This invention pertains a system and methods for ablation treatment of tissues. The invention aims to improve current models that allow predicting the volume and geometry of thermal ablations. Particularly the invention consists in a method that allows accounting for effects that occur when vapor that forms at the ablation site is able to seep in cavities that might encroach the ablation site and to deliver heat to the tissues of those cavities, creating an ablation geometry that is not described by current ablation models.
