Ultrasound-guided prostate percutaneous intervention robot system and calibration by informative particle swarm optimization

Frontiers of Mechanical Engineering 2022, Volume 17, Issue 1, Pages 3-3 doi: 10.1007/s11465-021-0659-x

Abstract: Applying a robot system in ultrasound-guided percutaneous intervention is an effective approach for prostate cancer diagnosis and treatment. The limited space for robot manipulation restricts structure volume and motion. In this paper, an 8-degree-of-freedom robot system is proposed for ultrasound probe manipulation, needle positioning, and needle insertion. A novel parallel structure is employed in the robot system for space saving, structural rigidity, and collision avoidance. The particle swarm optimization method based on informative value is proposed for kinematic parameter identification to calibrate the parallel structure accurately. The method identifies parameters in the modified kinematic model stepwise according to parameter discernibility. Verification experiments prove that the robot system can realize motions needed in targeting. By applying the calibration method, a reasonable, reliable forward kinematic model is built, and the average errors can be limited to 0.963 and 1.846 mm for insertion point and target point, respectively.

Construction of the vessel-collateral theory and its guidance for prevention and treatment of vasculopathy

Yiling Wu

Frontiers of Medicine 2011, Volume 5, Issue 2, Pages 118-122 doi: 10.1007/s11684-011-0140-z

Abstract: According to the self-discipline of traditional Chinese medicine, vessel-collateral theory was constructed systematically, which was important to improving prevention and treatment level of vasculopathy. The hypothesis of “homeostasis ( ), compensatory auto-adaptation ( ), regulation ( ) and equilibrium ( )” based on the “qi–yin-yang–five elements” coupled with the (nutrients)- (defense) theory, has become the core content of the vessel-collateral theory. Clinical and laboratory trials have been developed to further confirm the scientific connotations of the hypothesis, such as capsule, as the representative drugs of vessel collateral theory, showed good efficacy in protecting the vascular endothelium, stabilizing the vulnerable plaque and reducing the blood vessel spasm. “Sou, ti, shu, tong” was the characteristics of capsule in treating “microvascular damage” as the core mechanism of acute myocardial infarction, cerebral infarction and microvascular complications of diabetes. capsules in the treatment of arrhythmia have made integrated adjustment advantage. capsules have been made treating both manifestation and root cause of chronic heart failure. These research have improved prevention and treatment level of major vascular system diseases.

Strategic Guidance Effect of Large-Scale Construction Enterprise Growth to Programme Contracting

Feng Guo,Yi-qi Chen,Yi-qing Cai

Frontiers of Engineering Management 2016, Volume 3, Issue 3, Pages 246-251 doi: 10.15302/J-FEM-2016034

Abstract: In the case of single project management standing the major place, the management on the organizational level and project level is separated from each other in large-scale construction enterprises, and it is not long before program management theories applied to construction industry. Under the new situation of construction project clustering, how to choose projects has been the strategic decision for construction enterprises. Therefore, with the theory of program management and strategic management, this paper analyzes the relationship between the strategic growth of large-scale construction enterprises and program contracting, and attempts to provide meaningful ideas for enterprises to choose program from the strategic level.

Edge detection of steel plates at high temperature using image measurement

Qiong Zhou, Qi An

Frontiers of Mechanical Engineering 2009, Volume 4, Issue 1, Pages 77-82 doi: 10.1007/s11465-009-0013-1

Abstract: An edge detection method for the measurement of steel plate’s thermal expansion is proposed in this paper, where the shrinkage of a steel plate is measured when temperature drops. First, images are picked up by an imaging system; a method of regional edge detection based on grayscales’ sudden change is then applied to detect the edges of the steel plate; finally, pixel coordinates of the edge position are transformed to physical coordinates through calibration parameters. The experiment shows that the real-time, high precision, and non-contact measurement of the steel plate’s edge position under high temperature can be realized using the imaging measurement method established in this paper.
