| 20080199059 | Information Enhanced Image Guided Interventions - Linking of interventional and real time ultrasonic information with nonereal time anatomical information of, for example, a vessel or a tumor vascularization provided by x-ray rotational angiography requires high computational performance. According to an aspect of the present invention, an ultrasonic reference image is calibrated with respect to a high quality image acquired by a different imaging system. Then, during operational intervention, a registration or calibration of a data set acquired during the intervention is performed with respect to the reference image and not (as in state of the art devices) to the high quality image. Advantageously, this may allow for a fast fusion of the high quality image with the real time images and therefore allow for an improved tracking of operational interventions performed on a patient. | 08-21-2008 |

| 20100266175 | IMAGE AND DATA SEGMENTATION - Approaches to segmentation or detection of objects and their boundaries in images (or other data sets) do not rely on machine learning approaches that aim to minimize pixel-level agreement between a computer and a human. Optimizing such pixel-level agreement does not, in general, provide the best possible result if boundary detection is a means to the ultimate goal of image segmentation, rather than an end in itself. In some examples, end-to-end learning of image segmentation specifically targets boundary errors with topological consequences, but otherwise does not require the computer to “slavishly” imitate human placement of boundaries. In some examples, this is accomplished by modifying a standard learning procedure such that human boundary tracings are allowed to change during learning, except at locations critical to preserving topology. | 10-21-2010 |

In the first stage, bright and red regions are extracted from the fundus image. An optic disc has similar structural appearance as bright lesions, and the blood vessel regions have similar pixel intensity properties as the red lesions. Hence, the region corresponding to the optic disc is removed from the bright regions and the regions corresponding to the blood vessels are removed from the red regions. This leads to an image containing bright candidate regions and another image containing red candidate regions. In the second stage, the bright and red candidate regions are subjected to two-step hierarchical classification. In the first step, bright and red lesion regions are separated from non-lesion regions. In the second step, the classified bright lesion regions are further classified as hard exudates or cotton-wool spots, while the classified red lesion regions are further classified as hemorrhages and micro-aneurysms. In the third stage, the numbers of bright and red lesions per image are combined to generate a DR severity grade.

| 20160379364 | METHODS AND APPARATUS FOR ANALYSING EMBRYO DEVELOPMENT - Apparatus and methods for helping a user establish values (e.g. timings) for a plurality of parameters of interest (e.g. cell divisions) relating to the development of an embryo from a series of images of the embryo are described. For each parameter of interest an image is selected for display to a user seeking to establish a value for the parameter of interest. For example, the selected image may be an image predicted to be an image reflecting the value for the parameter of interest. For example, the selected image may be based on a calculated timing for a particular developmental event. The timing may be calculated from a numerical analysis of the images or maybe predetermined. If the user is unable to determine a value for the parameter of interest from the selected image, the user may scroll through neighbouring images until the user can determine a value for the parameter of interest. A value for the proud of interest may then be established in response to user input, for example a user providing an indication that a timing associated with a currently displayed image from the series of images should be taken to be the value of the parameter of interest. The different parameters of interest may be established in an iterative manner in which an initial image for display to a user is selected for each parameter of interest based on the parameter of interest. | 12-29-2016 |
