“…The results show that during the course of treatment, the value of the target positioning error was reduced by 89%, while the treatment time increased by no more than 1%. Anthony L. et al [ 5 ] at the Georgia Institute of Technology introduced the design, manufacture, modeling, and bench characteristic testing of a CT-guided parallel robot, and proposed a new breathing motion compensation protocol (RMCP) for the accurate positioning of robot-assisted abdominal RFA needles, as shown in Figure 2 . The robot consists of a Stewart platform and a friction-driven drum insertion module that uses a custom-designed breath-sensing pad for motion gating, eliminating the need for continuous CT motion gating.…”

Malignant tumors have become one of the serious public health problems in human safety and health, among which the chest and abdomen diseases account for the largest proportion. Early diagnosis and treatment can effectively improve the survival rate of patients. However, respiratory motion in the chest and abdomen can lead to uncertainty in the shape, volume, and location of the tumor, making treatment of the chest and abdomen difficult. Therefore, compensation for respiratory motion is very important in clinical treatment. The purpose of this review was to discuss the research and development of respiratory movement monitoring and prediction in thoracic and abdominal surgery, as well as introduce the current research status. The integration of modern respiratory motion compensation technology with advanced sensor detection technology, medical-image-guided therapy, and artificial intelligence technology is discussed and analyzed. The future research direction of intraoperative thoracic and abdominal respiratory motion compensation should be non-invasive, non-contact, use a low dose, and involve intelligent development. The complexity of the surgical environment, the constraints on the accuracy of existing image guidance devices, and the latency of data transmission are all present technical challenges.

“…Radiofrequency ablation (RFA) is an effective minimally invasive treatment for a variety of solid tumor cancers, including those of the lung, breast, kidney, pancreas, and liver. However, effective RFA for abdominal tumors relies on precise ablation needle targeting, which can be a challenging task due to respiratory movement [ 5 ].…”
