Technique for parallel MRI imaging (k-t grappa)

The subject invention relates to a method for reconstructing a dynamic image series. Embodiments of the subject invention can be considered and/or referred to as a parallel imaging-prior-information imaging (parallel-prior) hybrid method. A specific embodiment can be referred to as k-t GRAPPA. The subject method can involve linear interpolation of data in k-t space. Linear interpolation of missing data in k-t space can exploit the correlation of the acquired data in both k-space and time. Several extra auto-calibration signal (ACS) lines can be acquired in each k-space scan and the correlation of the acquired data can be calculated based on the extra ACS lines. In an embodiment, ACS lines can be calculated based on other acquired data, such that values in an ACS line can be partially acquired and the unacquired values can be calculated and filled in based on the acquired values. In a preferred embodiment, no extra training data is used and no sensitivity map is used. In an embodiment, the extra ACS lines can be directly applied in the k-space to improve the image quality. Because the correlations exploited via the subject method are local and intrinsic, the subject method does not require that the sensitivity maps have no change during the acquisition. Advantageously, the subject method can be utilized when sensitivity maps change, preferably slowly, during the acquisition of the data.

Autonomous gardening vehicle with camera

ActiveCN104714547AExpected to operate autonomouslyMowersWatering devicesTerrainDrive wheel
Method for generating scaled terrain information with an unmanned autonomous gardening vehicle (1), the gardening vehicle (1) comprising a driving unit comprising a set of at least one drive wheel (5) and a motor connected to the at least one drive wheel for providing movability of the gardening vehicle (1), a gardening-tool (7) and a camera (10a-b) for capturing images of a terrain, the camera (10a-b) being positioned and aligned in known manner relative to the gardening vehicle (1). In context of the method the gardening vehicle (1) is moved in the terrain whilst concurrently generating a set of image data by capturing an image series of terrain sections so that at least two (successive) images of the image series cover an amount of identical points in the terrain, wherein the terrain sections are defined by a viewing area of the camera (10a-b) at respective positions of the camera while moving. Furthermore, a simultaneous localisation and mapping (SLAM) algorithm is applied to the set of image data and thereby terrain data is derived, the terrain data comprising a point cloud representing the captured terrain and position data relating to a relative position of the gardening vehicle (1) in the terrain. Additionally, the point cloud is scaled by applying absolute scale information to the terrain data, particularly wherein the position data is scaled.

Soil body image real time capturing method and system used for centrifugal machine model trial

ActiveCN101158571AAvoid interference from strong electromagnetic fieldsStrong electromagnetic field interference overcomePhotogrammetry/videogrammetryUsing optical meansInternal memoryDisplay device
The invention provides a soil body image real-time acquisition method and system used for a centrifuge model test and belongs to geotechnical engineering test and measuring technology field. By installing computers on a swiveling jib of the centrifuge, the invention finishes the acquisition and storage of the image in the centrifuge, avoids the interference of a strong electromagnetic field in a slip ring and ensures the quality of the collected image, thus the precision of the analysis is improved effectively; the combining use of a high-speed camera and a way of step storing that the image is first stored in real time into an internal memory and then restored into a hard disc realizes the acquisition and real-time storage of image series with high-speed and strong resolution when the centrifuge is running; by using a LAN built by a cross network cable passing through the slip ring of the centrifuge, the interference of the strong electromagnetic field in the slip ring caused by high-speed rotation of the centrifuge can be overcome, thus realizing real-time control of the computers by a control room, and meanwhile pictures shot by the high-speed camera are mapped onto a monitor of a control machine.

Magnetic resonance imager, method and program which continuously applies steady-state free precession to k-space

A magnetic resonance imager for forming images of a moving portion of a patient includes imaging coils. The imager includes a computer that causes the imaging coils to apply continuously steady-state free precession to k-space of a magnetic resonance image series of the patient and acquire the image series, and generates images from the image series. A method for forming images of a moving portion of a patient includes the steps of applying continuously steady-state free precession to k-space of a magnetic resonance image series of a patient. There is the step of acquiring the image series. There is the step of generating images from the image series. A method for forming images of a patient includes the steps of triggering a steady-state free precision imaging sequence to an ECG r wave of cardiac cycles of the patient. There is the step of performing the steady-state free precision imaging sequence with imaging coils of a magnetic resonance imaging scanner such that data for a series of k-space data sets associated with the imaging sequence are acquired in a manner that is time resolved through the cardiac cycle, with data acquired over a number of consecutive cardiac cycles. A computer program embodied on a computer readable medium to form an image of a patient with an MRI.
