摘要:
An apparatus comprises: a database (30) storing medical data including image medical data and non-image medical data for a plurality of patients; a digital processor (40) configured to (i) generate a features vector (56) comprising features indicative of a patient derived from patient medical data stored in the database including both patient image medical data and patient non-image medical data and (ii) perform multivariate analysis (64) on a features vector generated for a patient of interest to determine a proposed diagnosis for the patient of interest; and a user interface (42) configured to output a human perceptible representation of the proposed diagnosis for the patient of interest.
摘要:
This invention relates to a method and a system of evaluating toxicity level of a patient undergoing a cancer treatment protocol. Patient's related data including biomarkers of toxicity level caused by said cancer treatment are received. These biomarkers of toxicity level are then compared with a range of reference biomarkers of toxicity level caused during a similar cancer treatment. Finally, an alert signal is issued in case the biomarkers of toxicity level fall outside said range of reference biomarkers of toxicity level.
摘要:
An oncology therapy method comprises implanting a radioactive seed (10, 20, 30, 40, 50) in an oncology subject (S). In some embodiments the radioactive seed comprises a radioactive material (12, 32, 33, 42) including at least one radioisotope disposed in a biodegradable host (14, 24, 25, 44) configured to biodegrade over a therapy time period when implanted in the oncology subject. In some embodiments the radioactive seed is implanted in soft tissue of an oncology subject (S), and the radioactive seed comprises a radioactive material (12, 32, 33, 42) including at least one radioisotope disposed in a host material (14, 24, 25, 44) having softness comparable with or softer than the soft tissue into which the radioactive seed is implanted.
摘要:
A method includes obtaining an image of a region of interest of a subject, wherein the image is generated with image data produced by an imaging system used to scan the subject, obtaining a signal indicative of a physiological state of the subject before the scan, and displaying both the image and data indicative of the physiological state. In another aspect, a method includes correcting, via a processor, a tracer uptake value for a target region of interest based on a tracer uptake correction factor.

摘要:
Systems and methods for data acquisition in computed tomography (CT) applications are provided. The systems and methods are particularly adapted for scanning and acquiring/processing data in connection with high-power cone-beam CT applications. The electron beam is moved/scanned along the anode surface to multiple focal positions. Data acquisition for a full projection at one focus position and one view angle is achieved by activating each focus position multiple times during the data acquisition for one angle of the gantry. The detector array and associated data processing system are adapted to rapidly switch between the different focus positions during the acquisitions for one view angle and to collect all data belonging to the same projection into the same data set. Adaptive electron optics are utilized to move/scan the electron beam along the anode surface to the various focus positions. Alternatively, a plurality of cathodes may be provided for respective focus positions and the system may support fast switching therebetween to achieve desirably short spot times. The disclosed CT system permits greater power densities without risk of heat damage to the anode and effectively increases the track velocity of the electron beam on the anode surface. The CT system and associated data acquisition methods have particular utility in CT applications requiring increased time resolution and/or spatial resolution, e.g., cardiac CT applications.

A computer program product is also provided.
摘要:
The present invention relates to a device for separating at least one analyte in a liquid sample and further analyzing said analyte by laser desorption/ionization (LDI) mass spectrometry. The invention is further concerned with the use of devices for separating at least one analyte in a liquid sample and subsequent determination of the presence and/or amount of said at least one analyte by LDI mass spectrometry. The invention is also concerned with a method for separating at least one analyte in a liquid sample and subsequent determination of the presence and/or amount of said at least one analyte by LDI mass spectrometry.
摘要:
An improved radiation therapy planning procedure is suggested. The procedure comprises the steps of specifying and determining the absolute grade of cell degeneracy by in-vitro tests, whereby marker(s) indicative for specific cell degeneracy are detected and quantified, establishing a biology-based segmentation of areas with similar grade of relative cell degeneracy and applying the absolute grade of cell degeneracy to the biology-based segmentation data, thereby establishing an improved radiation therapy planning procedure. Moreover, the present invention suggests a system for an improved radiation therapy planning procedure and its use in procedures of diagnosis and/or therapy management of cancer.
