20080200808 | DISPLAYING ANATOMICAL PATIENT STRUCTURES IN A REGION OF INTEREST OF AN IMAGE DETECTION APPARATUS - A method and device for detecting and displaying an anatomical patient structure in a region of interest of a movable image detection apparatus such as an ultrasound probe. After the region of interest is defined in a patient coordinate system, movement of the image detection apparatus can be tracked, and the position of the region of interest can be changed or shifted to compensate for the movement of the image detection apparatus. | 08-21-2008 |
20100185100 | IDENTIFYING AND LOCALIZING TISSUE USING LIGHT ANALYSIS - The invention relates to a method for identifying and localizing body tissue, in which a light beam emitted from a tissue point or tissue region of interest is on the one hand positionally determined with the aid of an optical medical tracking system and is on the other hand analyzed with respect to its light properties, in order to determine from this the nature of the tissue point or tissue region. It also relates to a device for identifying and localizing body tissue, comprising: an optical medical tracking system which detects a light beam emitted from a tissue point or tissue region of interest and positionally determines the location of the tissue point or tissue region; and a light analyzer which analyses the light beam with respect to its light properties, in order to determine from this the nature of the tissue point or tissue region. | 07-22-2010 |
20100232666 | MEDICAL IMAGE REGISTRATION BY MEANS OF OPTICAL COHERENCE TOMOGRAPHY - The invention relates to a medical image registration method in which an actual part of a patient's body is locationally assigned to a stored image of the part of the body with computer assistance, wherein the part of the patient's body comprises a rigid structure and a soft-tissue structure above it, wherein the location of at least one reference point on the rigid structure is ascertained, through the closed soft-tissue structure, by means of optical coherence tomography (OCT), when detecting the actual spatial location of the part of the body. It also relates to a pointer unit of a medical image registration apparatus, which comprises an optical coherence tomography (OCT) scanner or its emitting unit. | 09-16-2010 |

20150150645 | OPTICAL SAMPLING OF SURFACE POINTS FOR MEDICAL NAVIGATION - A method for sampling surface points on the surface of an object using a medical navigation system and a light beam source, wherein the light beam source generates a light beam which creates a light spot on the surface, and a camera of the medical navigation system records image data from which the location of the light spot is determined as the location of a sample point, said method comprising the steps of: generating a quality measure for a sample point using a quality measurement device which is at least partially attached to the light beam source and used to determine quality measurement data from which the quality measure is determined; and processing the sample point on the basis of the quality measure. | 06-04-2015 |
20150351718 | METHOD AND APPARATUS FOR CALCULATING THE CONTACT POSITION OF AN ULTRASOUND PROBE ON A HEAD - A data processing method for calculating the contact position of a medical ultrasound transceiver on the head of a patient, comprising the steps of: a) acquiring ROI data which represent a region of interest (ROI) corresponding to at least a part of a vessel in a vascular structure; b) acquiring contact region data which represent a contact region for the ultrasound transceiver on the head, wherein the contact region corresponds to one or more acoustic windows; c) determining at least one target point in the region of interest; d) determining at least two entry points on the contact region; e) calculating a set of lines which comprises the lines between the two points of each respective possible pair consisting of one entry point and one target point; f) eliminating lines which pass through a bony structure other than the bone immediately beneath the contact region; g) calculating a score for each of the remaining lines; and h) selecting the entry point of the line with the highest score as the contact position of the ultrasound transceiver. | 12-10-2015 |
