The Effect of Increasing C-arm SID: Improving Image Resolution and Positioning Accuracy

图片
The Effect of Increasing  C-arm  SID: Improving Image Resolution and Positioning Accuracy SID is an important technical parameter in C-arm system s. It refers to the distance from the focal point (filament) of the X-ray tube to the image receptor, also known as source-to-image distance or focus-to-screen distance. The adjustment of SID in C-arm equipment has various impacts on clinical operations and imaging results. Increasing the SID primarily affects the following three aspects: Optimizing Image Resolution and Geometric Accuracy Increasing the SID reduces the geometric magnification effect , minimizing edge blurring and distortion caused by excessive magnification. This improves both image resolution and positioning accuracy. This is especially important in surgeries requiring high-precision positioning, such as orthopedic 3D imaging and vascular interventions. Expanding the Surgical Workspace By increasing the SID through adjusting the position of the flat-panel detector, ...

Differences Between Mobile CT and Conventional CT: Detailed Explanation of the Advantages of Mobile Intraoperative CT

图片
  Conventional CT (Computed Tomography) refers to fixed, enclosed CT scanners, while Mobile CT (Portable CT) refers to movable, open CT scanners. Mobile CT offers greater flexibility and convenience compared to traditional CT scans, providing numerous benefits for medical staff. Conventional CT  machines are typically large and heavy, requiring installation in specific hospital rooms. Patients must be transported to the examination area for scans, which can be challenging for those with limited mobility. It has been reported that over 71% of ICU patients experience adverse events during transport to the CT room. Additionally, hospitals often have a limited number of CT scanners, leading to longer wait times for scans and reports. Mobile CT devices  come in two types: mobile vehicle-mounted CT and mobile intraoperative CT (3D C-arm X-ray machines). Vehicle-Mounted CT  can be transported to various locations, including remote areas and emergency sites. This system inte...

What are the advantages of using an orthopedic surgical navigation system to assist in surgery (more accurate, safer)?

图片
  With the rapid development of artificial intelligence, robot-assisted surgery has advanced rapidly in the field of surgery. The orthopedic  surgical navigation system , also known as the orthopedic surgery robot, is designed to utilize preoperative/intraoperative imaging data to plan the surgical path and guide the surgeon to complete the surgery along the planned path using the guidance of the robotic arm. This system simplifies and standardizes complex surgeries, providing surgeons with greater operating space and more accurate anatomical layers, ensuring the successful completion of complex surgeries in confined spaces. What are the benefits of orthopedic  surgical navigation systems  for patients? First, it is important to clarify that in robotic surgery, the robot performs auxiliary operations during the surgery. Based on three-dimensional data obtained from imaging scans like the 3D C-arm, the robotic system uses surgical planning software to guide the surgeo...

What’s the difference between navigation and localization in surgical robots?

图片
  In recent years, surgical robotics has been widely used, and robot-assisted surgery has become more and more popular around the world. Utilizing advanced robotics technology with high-precision image navigation and localization technology, surgical robots are able to achieve precise surgical operations and efficient treatment results. Among them, localization and navigation technology is a core component in robot-assisted surgery and a key factor affecting the quality and effect of surgery. Navigation and localization of surgical robots Navigation of the surgical robot: Navigation is an important part of surgical route planning and surgical path guidance in robot-assisted surgery. Through reasonable navigation planning, it can reduce surgical time, minimize surgical risk and improve surgical efficiency. The navigation technology widely used in robot-assisted surgery has the following two main aspects: Reverse planning navigation technology Reverse planning navigation technology i...

Types Of Medical Robotics

  As robotic technology rapidly advances, many medical robots are now in use. In this article, we will explore some types of medical robots and their basic functions. Surgical robots Surgical robots enable surgical procedures to be performed with greater precision than a human surgeon can achieve unaided. Additionally, they facilitate remote surgeries, allowing a surgeon to operate on a patient without being physically present. Robotic technology for assisting precise surgeries has rapidly developed in recent years, and there are now many different types of surgical robots available on the market. The following 10 brands of robots are some of the most well-regarded in the industry. Perlove Medical Robot Perlove Medical Robot is mainly used to assist with spinal surgery, including spinal deformity surgery, fusion surgery, tumor surgery, sacroiliac joint fixation surgery and thoracolumbar spine surgery. Da Vinci® Surgical Robot ROSA® Robotics ROSA Robotics is applicable to knee, hip,...
