A stereotactic device for use with an imager such as a magnetic resonance imager is disclosed, which permits an imaging scan to be taken with reference to a personal coordinate system (or PCS) that is independent of a machine coordinate system (or MCS). Methods using the device to obtain imaging scans are described such that the imaging scans are superimposable even if taken at different time periods using the same or a different imager. The device comprises a frame that can be reproducibly positioned on a subject and which is equipped with non-invasive affixing means and localizing means that provide the PCS. The device and methods of the invention are particularly well suited for routine initial or follow-up examinations, pre-surgical planning and post-surgical evaluation. Markers on a stereotactic device can be tracked during an MRI scan to compensate for patient motion during the scan.

High resolution B-mode ultrasound images of the common carotid artery are obtained with an ultrasound transducer using a standardized methodology. Subjects are supine with the head counter-rotated 45 degrees using a head pillow. The jugular vein and carotid artery are located and positioned in a vertical stacked orientation. The transducer is rotated 90 degrees around the centerline of the transverse image of the stacked structure to obtain a longitudinal image while maintaining the vessels in a stacked position. A computerized methodology assists operators to accurately replicate images obtained over several spaced-apart examinations. The methodology utilizes a split-screen display in which the arterial ultrasound image from an earlier examination is displayed on one side of the screen while a real-time “live” ultrasound image from a current examination is displayed next to the earlier image on the opposite side of the screen. By viewing both images, whether simultaneously or alternately, while manually adjusting the ultrasound transducer, an operator is able to bring into view the real-time image that best matches a selected image from the earlier ultrasound examination. Utilizing this methodology, measurement of vascular dimensions such as carotid arterial IMT and diameter, the coefficient of variation is substantially reduced to values approximating from about 1.0% to about 1.25%. All images contain anatomical landmarks for reproducing probe angulation, including visualization of the carotid bulb, stacking of the jugular vein above the carotid artery, and initial instrumentation settings, used at a baseline measurement are maintained during all follow-up examinations.

A method automatically segments the heart and abdominal aorta from volumetric images without the need to inject iodine contrast media into the subject. The method automatically quantifies arterial plaque (hard plaque, soft plaque or both) in the cardiovascular system. Plaque definitions include subject specific in vivo blood / muscle density measurements, subject specific voxel statistical parameters and 2-D and 3-D voxel connectivity criteria, which are used to automatically identify the plaques. The locations and outlines of the major arteries are determined in a 3-D coordinate system and the specific coordinates of the detected plaques are displayed in a plaque map for follow-up exams or ease in plaque review and reporting the results.

An imaging method and system allow duplicated repetition of a procedure to acquire image data from the interior of the body of a patient and to generate an image of the interior of the body of the patient with an initial imaging modality, that is operated using patient-specific examination parameters to implement a procedure to acquire the image data and generate the image. The patient-specific examination parameters are electronically stored, and are electronically retrieved to implement a duplicate of the aforementioned procedure in an imaging modality-assisted follow-up examination.

In a method for the operation of a medical diagnosis apparatus in an examination, a region of an examination subject to be imaged is placed in an imaging volume of the diagnosis apparatus, a first dataset of the region of interest is registered with a first set of operating parameters of the diagnosis apparatus, and the first set of operating parameters and the first dataset are stored. In a follow-up examination wherein the region of interest is again placed in the imaging volume, a follow-up dataset of the region of interest is registered with the apparatus operated with the stored, first set of operating parameters and the follow-up dataset is stored.

A method for determining a change over time in a biomarker in a region to be examined of a patient is provided. The change is determined from magnetic resonance data using a magnetic resonance measuring system with sequences and protocols for measuring the biomarkers by functional resting state connectivity by rsfMRI, perfusion values, magnetic resonance spectra of voxels, or morphometry of organs. A control unit has programs which evaluates the biomarker and a data memory which stores the results of the evaluation and additional data. During a first examination, a quantity result of the biomarkers is determined and stored in the data memory. During a follow-up examination, at least one previous item of the result and additional data from the first examination stored in the data memory are used for determining a quantitative change in the biomarker.

The invention discloses a family planning gynecological examination bed, which comprises a base, a support platform is fixedly installed on the top of the base, a support block is fixedly installed on the top of the support platform, and a horizontally arranged A fixed plate, the left end of the fixed plate is rotatably hinged to a rotating plate, and the front and rear sides of the fixed plate are respectively rotatably equipped with support frames. The family planning gynecological examination table of the present invention can completely expose the private parts of women to be examined in the field of vision of medical staff, so as to ensure the smooth progress of subsequent examinations, and save time and effort during adjustment and use, which is convenient for medical staff to perform gynecological examinations , due to the use of mechanized operation, it is convenient for medical staff to adjust and use the woman's body position according to the examination needs, the operation is relatively simple, and the work difficulty of medical staff is reduced, so it is suitable for popularization and application.

The invention discloses a primary examination instrument for oncology clinical use, which comprises a preliminary examination mixing device 1, a preliminary examination mixing device 2 is movable installed above the preliminary examination mixing device 1, and a preliminary examination mixing device 2 is movable above the preliminary examination mixing device 2. There is a fixture device, and the front of the first inspection mixing device is provided with a control panel and a power socket located on the side below the control panel. In the present invention, the blood in the primary test reagent tube and the detection reagent are mixed simultaneously in the left and right directions and up and down directions, so that the blood in the primary test reagent tube can be mixed evenly with the detection reagent conveniently and quickly, thus avoiding manual mixing by people In addition, it can simultaneously mix the blood and detection reagents in multiple primary test reagent tubes at one time, greatly improving the work efficiency, so that the follow-up inspection work can be carried out, which is beneficial to people's use.

A medical selection system 100 for generating selection data includes a user input 110 for enabling a user to establish a selection of one or more medical images amongst a plurality of medical images 182 for establishing the one or more medical images as baseline images for use in a follow-up examination of a patient. A processor 120 generate selection data 132 being indicative of said selection, and includes selection metadata in the selection data for enabling associating the selection data with the plurality of medical images. An output 130 provides the selection data to a medical processing system 150 for enabling the medical processing system to select, based on the selection data, the one or more medical images amongst the plurality of medical images for use as the baseline images in the follow-up examination of the patient.
