Abstract: Methods and apparatus for computer-aided prostate condition diagnosis are disclosed. An example computer-aided prostate condition diagnosis apparatus includes a memory to store instructions and a processor. The example processor is to execute the instructions to implement at least a prostate assessor, a lesion assessor, and an outcome generator. The example prostate assessor is to evaluate a volume and density of a prostate gland in an image of a patient to determine a prostate-specific antigen level for the prostate gland. The example lesion assessor is to analyze a lesion on the prostate gland in the image. The example outcome generator is to generate an assessment of prostate gland health based on the prostate-specific antigen level and the analysis of the lesion.

Abstract: A method and an image processing system for the evaluation of projection images generated by an X-ray imaging system, wherein the images may show different instruments of a given set of interventional instruments like catheters or guide wires. The instruments are equipped with markers such that their configuration is characteristic of the corresponding instrument. Preferably three markers are arranged on a straight line, the ratio of the distances between them being characteristic for the corresponding instrument. The image processing system may then identify the instruments present in a given projection and provide functionalities for a user that correspond to said instruments. Moreover, the system may be used to locate an instrument of interest in a projection image if the marker configuration of that instrument is known a priori.

Abstract: A medical viewing system for displaying a sequence of medical images that represents moving and/or positioning a guide-wire in a blood vessel, which guide-wire has a guide-wire tip that is contrasted with respect to the guide wire, this system comprising acquisition means that acquires an original sequence of noisy images called live sequence and processing means for processing said live sequence of images in real time, the processing means comprising: first means (10) for automatically detecting the guide-wire tip, yielding skeleton information of the guide-wire tip and a field of motion vectors based on said skeleton information; second means (20) for automatically registering the guide-wire tip with respect to a reference based on the field of motion vectors and for enhancing the guide-wire and the vessel walls while blurring the background in the registered images; and comprising: Display means for displaying a live sequence of processed images.

Abstract: The invention relates to a system and a method for detecting an object of interest in a sequence of medical images. Said viewing system comprises alarm detection means (20) for detecting a set of alarms of said object of interest in a medical image (I?) at time t, in which an alarms is a set of data describing a possible location of the object. It further comprise temporal tracking means (30) for iteratively creating a set of tracks (T?) at time t by associating alarms of said set of alarms (A?) with tracks (T?1) at time t?1 and for choosing a track from among said set of tracks at time t in accordance with a merit criterion. Said track at time t is ended by an alarm which corresponds to a detection of said object of interest in said medical image at time t. Said viewing system advantageously accumulates temporal proofs for confirming or infirming spatial detections of alarms at time t. Detection of the object of interest is therefore made more robust to errors.
