摘要:
A method of processing a positron emission tomography (PET) imaging data set (30) acquired of a subject includes independently localizing each positron-electron annihilation event of the PET imaging data set based on time of flight (TOF) localization of the positron-electron annihilation event to form a generated image (34). The generated image may be displayed. The generated image is suitably used as the basis for an initial image of an iterative reconstruction (40) of the PET imaging data set (30) to produce a reconstructed image (42). A spatial contour (56) of an image of the subject in the PET imaging data set (30) is suitably delineated based on the generated image (34). A subject attenuation map (62) for use in PET image reconstruction (40) is suitably constructed based in part on the spatial contour (56).

A torque detecting system for a bottom bracket axle of a power-assisted bicycle includes a torque sensor for being mounted on the bottom bracket axle of the bicycle, a wireless signal transmitter arranged stationarily relative to the bottom bracket axle, and a wireless signal receiver for being arranged at a location of a bicycle frame of the bicycle in proximity to the bottom bracket axle. The wireless signal transmitter is adapted for receiving a detected signal, which is outputted from the torque sensor, and then transmitting the detected signal to the wireless signal receiver wirelessly. In this way, the signal attenuation and the possibility of signal loss of the detected signal can be minimized during the signal transmission, such that the torque applied on the bottom bracket axle by the bicyclist can be detected precisely.

A spectrum shaping scheme for chirped pulse amplification (CPA): uses a spectrum decomposing system with CTSI construction, a spectrum synthesizing system with CTSI structure that is symmetrical to the decomposing structure, and a spectrum shaping system including an aperture and a planar reflector for spectrum shaping function design. The scheme includes the following steps: firstly decomposing the spectrum of a chirped temporal pulse laser to a spectral domain; then shaping the spectrum in the spectral domain; finally synthesizing un-shiftily this shaped spectrum in the spectral domain into a temporal chirped pulse with a designed shape. The scheme has the benefit that it can be not only utilized in a general laser spectrum shaping and spectrum modulation, but also can be utilized for a high energy and ultra-high peak-power laser system in chirped pulse amplification with a large caliber and with a chirped pulse bandwidth of a few nanometers.

A data card includes a circuit board, a holder, an upper cover, a connecting wire, and an interface. The circuit board is fixed in the holder. One end of the flexible connecting wire is connected with the circuit board, and the other end of the flexible connecting wire is connected with the interface. The upper cover covers the holder. When the data card is idle, the interface and the flexible connecting wire are located in the cavity formed by the upper cover and the holder. When the data card is connected with an external device by the interface, the interface is located outside the cavity formed by the upper cover and the holder. The data card enables flexible adjustment of the location of the interface, and fixes the upper cover on the data card when the data card is connected for use.
