Problems solved by technology

However, this maximum value may not correspond to a clinically acceptable "best" registration, forcing physicians to perform time-consuming and tedious manual alignment of the dataset intraoperatively
[0007] Furthermore, a problem common to the fusion of real patient data is that there are multiple local maxima in the similarity function, which will have similar cost values

Embodiment Construction

[0026] Referring to the drawings, wherein like reference numerals designate like or similar elements, figure 1 is a schematic diagram showing the main parts of a system 10 for carrying out the method according to the invention. In its most basic form, the system 10 includes two imaging systems 12 , 14 connected to a processor 16 which is also connected to a display 18 , storage components containing a clinical data set 20 and a graphical user interface (GUI) 22 . Although shown separately, GUI 22 may be integrated into display 18, ie, a touch screen display.

[0027] figure 2 A flowchart of a method is shown for composing and presenting a list of registration transformations to a physician to enable the physician to select a registration transformation to use during surgery. Although the description refers to presenting the list to a doctor, it is understood that the invention can also be used by other types of people who need to use image transformations.

Abstract

System and method for enabling intra-operative selection of an image registration transformation for use in displaying a first image dataset and a second image dataset in correspondence with one another. Image dataset acqusition devices (12, 14) obtain the first and second image datasets. A similarity function indicative of a likelihood that the first and second image datasets are in correspondence with one another is computed by a processor (16) and then a ranking of each of a plurality of local maxima of the similarity function is determined. Registration transformations derived from a plurality of the local maxima are displayed on a display (18), and using a user-interface (22), a physician can select each registration transformation to ascertain visually whether it is the clinically-optimal registration transformation for subsequent use.

Description

technical field [0001] The present invention relates generally to a system for enabling selection of image registration transformations, and more particularly to a system for enabling physician-guided selection of clinically optimal registration transformations during surgery for Transforming image datasets obtained before or during surgery into the coordinate space of other image datasets obtained, for example during invasive interventional procedures. [0002] The present invention also relates to a method for enabling a physician during an invasive surgical procedure to select one of a plurality of simultaneously displayed registration transformations for transforming a preoperative or intraoperative image dataset The coordinate space of other image datasets obtained during the process. Background technique [0003] Image guidance is playing an increasingly important role in minimally invasive interventional procedures, such as those routinely performed in clinical EP la...
