摘要： A Computer Aided Diagnosis, CADx, system (200) is described that comprises: at least one input (210, 212, 214) configured to provide at least one input medical image; and a CADx processing engine (220) configured to receive and process the at least one input medical image and produce at least one CADx score. A CADx score mapping circuit is operably coupled to the CADx processing engine (220) and configured to: map the at least one CADx score to a risk adjusted virtual score; and generate an output (235) of at least the risk adjusted virtual score associated with the processed at least one input medical image. The at least one CADx score and the risk adjusted virtual score correspond to an equivalent risk of condition or disease associated with a patient.

摘要： In a method and apparatus for analyzing medical imaging data of a subject from an imaging modality using a tracer, data from detection of tracer emission events at least one region of a scanned imaging volume are obtained, and the data processed to establish sub-periods or time points within a scan period for the emission events. A rate of change of emission events per unit time for a given region is then calculated, for example by obtaining a number of emission events in each sub-period in the given region, and fitting a line through the values for the sub-periods.

摘要： A method is described for acquiring and analysing the data produced by Positron Emission Tomography (PET), which method provides for an accurate estimation of vascular compartment volume, VB. An MRI scan and the PET scan is performed simultaneously and the results of the former is used to derive a value for VB. The value so derived is then used in pharmacokinetic modelling along with the results of the functional scan.

摘要： A method of computing a contour, such as the endocardial boundary in an ultrasound long-axis view of the heart, is disclosed. A plurality of points are input, each point being indicative of a predetermined landmark point in the image. A preliminary contour is then derived based on the input points and a known average contour shape which has been obtained from a database of contours derived from previous images. Finally, the preliminary contour is deformed to fit features identified in the image by a feature-extraction algorithm, to obtain the computed contour.

摘要： A technique for assessing the progression of multilateral dysfunction, e.g. bilateral diseases is described. The process consists of two stages: firstly, a ‘health measure’ is computed for each of the features of the multi-lateral dysfunction. One example is in terms of the progression of Parkinson's disease by applying it to the uptake of imaging agent in the two striata of the brain, which can be viewed using SPECT imaging. In this example, a characteristic graph for each striatum is matched to a family of such graphs in order to quantify the state of each striatum as a health measure. Then the lower health measure is plotted against the higher health measure. This point is then projected onto a previously computed disease progression trajectory which is used to assign a percentage to the progression of the disease, from 0% normal to 100% extreme progression of the disease. In addition to the disease progression percentage, the technique also provides a confidence measure of the accuracy of this estimation. The invention is applicable to other forms of multilateral dysfunction, including other human or animal conditions and dysfunction in non-biological systems such as mechanical, electrical or electronic systems.
摘要翻译：评估多发功能障碍进展的技术，例如描述双边疾病。该过程包括两个阶段：首先，为多侧功能障碍的每个特征计算“健康度量”。就帕金森氏病的进展而言，一个例子是通过将其应用于大脑两条纹状体中的成像剂的摄取，可以使用SPECT成像进行观察。在该示例中，每个纹状体的特征图与这样的图的族相匹配，以便将每个纹状体的状态量化为健康度量。然后，较低的健康指标与较高的健康度量相比较。然后将该点投影到先前计算的疾病进展轨迹上，该轨迹用于将疾病进展的百分比从疾病的0％正常到100％极端进展分配。除了疾病进展百分比，该技术还提供了该估计精度的置信度量度。本发明适用于其他形式的多边功能障碍，包括其他人或动物病症和非生物系统如机械，电气或电子系统中的功能障碍。
