Computed tomography device comprising an x-ray source and an x-ray detecting unit. The x-ray source comprises a cathode with a plurality of individually programmable electron emitting units that each emit an electron upon an application of an electric field, an anode target that emits an x-ray upon impact by the emitted electron, and a collimator. Each electron emitting unit includes an electron field emitting material. The electron field emitting material includes a nanostructured material or a plurality of nanotubes or a plurality of nanowires. Computed tomography methods are also provided.

A micro-radiation therapy apparatus includes an isotope-based micro-radiotherapy brachytherapy small animal irradiator useful for radiating a biological system, the irradiator having an external radiation source proximate the biological system comprising a collimated radiation beam. A method of effectively irradiating at least one cell in a biological system includes applying micro-radiation from an isotope-based micro-radiation small animal irradiator, the irradiator having an external radiation source proximate the biological system including a collimated radiation beam to a target cell of the biological system.

The invention discloses a method for directional cross-border detection and mixing line detection in a video. The method includes the following steps of S1, inputting a monitoring video, S2, initializing the video, wherein the mixing line and an interesting region are set in the video, and the minimum filtering movement target area is selected according to the resolution ratio of the input video to be detected, S3, detecting the foreground, wherein movement targets are detected and tracked, and the movement target needing to be detected is filtered out, S4, carrying out mixing line detection or cross-border detection, wherein the cross-border detection comprises the two phenomena of intrusion detection and fleeing detection, S5, carrying out the S3 and the S4 repeatedly for every later new movement target. By means of the method for directional cross-border detection and mixing line detection in the video, the movement targets are filtered, targets which do not need to be detected such as birds and small animals are excluded, detection accuracy is improved, detections of leaving and the movement direction of the movement target can be achieved on the basis of mixing line detection and intrusion detection, detection is fully functional, and the method better meets actual application requirements.
