Measurement of pectoralis major deformation during activities with M-mode ultrasound

摘要

Invasive incisions are inevitable in cardiac surgeries. It is clinical significant to explore the optimal locations of the incisions. What is more, the deformation of pectoralis major affects the proper healing of wounds in the patients with invasive surgery on the chest. Ultrasound, with the advantages of portability, non-invasiveness and no radiation, becomes a common method to measure the structural information of the human tissue in vivo. In this study, the deformation of pectoralis major was measured in real-time by the M-mode ultrasound signal acquisition device which can fasten the probe on the chest. The regularity of muscle deformation may provide basis for the choice of the incision position in surgical planning, as well as the optimization of rehabilitation exercises.
