Background: Over the years, medical image registration has been widely used in various fields. However, different application characteristics, such as scale, computational complexity, and optimization goals, can cause problems. Therefore, developing an optimization algorithm based on clustering calculation is crucial.
Method: To solve the aforementioned problem, a multiswarm artificial bee colony (MS-ABC) multi-objective optimization algorithm based on clustering calculation is proposed. This algorithm can accelerate the resolution of complex problems on the Spark platform. Experiments show that the algorithm can optimize certain conventional complex problems and perform medical image registration tests.
Result: Results show that the MS-ABC algorithm demonstrates excellent performance in medical image registration tests. The optimization results of the MS-ABC algorithm for conventional problems are similar to those of existing algorithms; however, its performance is more time efficient for complex problems, especially when additional goals are needed.
Conclusion: The MS-ABC algorithm is applied to the Spark platform to accelerate the resolution of complex application problems. It can solve the problem of traditional algorithms regarding long calculation time, especially in the case of highly complex and large amounts of data, which can substantially improve data-processing efficiency.

The high morbidity and mortality of colorectal cancer (CRC) is a major challenge in clinical practice. Although a series of alternative research models of CRC have been developed, appropriate orthotopic animal models that reproduce the specific clinical response as well as pathophysiological immune features of CRC are still lacking. In the current study, we constructed a CRC orthotopic xenograft model by implanting the tumor tubes at the colorectum of mice and monitored the model development using bioluminescence imaging.

Diffuse optical tomography (DOT) enables the in vivo quantification of tissue chromophores, specifically the discernment of oxy- and deoxy-hemoglobin (HbO and HbR, correspondingly). This specific criterion is useful in detecting and predicting early-stage neoadjuvant breast cancer treatment response. To address the issues of the limited channels in the fiber-dependent breast DOT system and limited signal-to-noise ratio in the camera-dependent systems, we hereby present a camera-based lock-in detection scheme to achieve dynamic DOT with improved SNR, which adopted orthogonal frequency division multiplexing technology.
