What is the difference between 3D C-arm and ordinary C-arm?

 Three-dimensional c-arm and ordinary c-arm what is the difference? The following domestic c-arm manufacturer “PUAI medical” for you to answer this question.

The full name of the c-arm is C-arm X-ray machine, which belongs to the class of X-ray photographic medical equipment, used for real-time dynamic imaging in surgery. It is called c-arm because the shape of its frame is a “C” shape, as shown in the figure below.

A 3D c-arm, also known as a 3D c-arm, is a c-arm with 3D CT imaging capabilities, whereas a regular c-arm has only 2D CT imaging capabilities.

Features of 3D c-arms:

Three-dimensional c-arm, also known as orthopedic three-dimensional c-arm machine, is mainly used in orthopedics, surgery, orthopedic surgery, spine surgery, abdominal surgery and so on.

The 3D c-arm combines the traditional two-dimensional and “CT-like mode”, which can quickly generate cross-sectional, sagittal, coronal tomographic images and three-dimensional stereoscopic images during the operation. Through the tomographic images in different directions, the anatomical results of the vertebral body and its accessories can be displayed more clearly and completely, and the three-dimensional spatial relationship between the lesion and the surrounding tissues can be analyzed intuitively, and the three-dimensional tomographic imaging can make the surgical simulation and the formulation of surgical plans more accurate.

Taking spinal surgery as an example, some studies have shown that in 3D c-arm image-guided lower cervical or thoracic posterior screw placement, the correct screw placement rate can reach 92.7%, and in 3D c-arm image-guided lumbar disc fusion, the total amount of the operator being irradiated is significantly reduced.

The current c-arm sales market, three-dimensional c-arm sales accounted for the total number of C-arms is not high, on the one hand, because many domestic c-arm manufacturers do not have c-arm three-dimensional imaging technology, on the other hand, three-dimensional c-arm price is higher than the ordinary c-arms, hospitals in the procurement of financial considerations.

Three-dimensional c-arm

Perlove Medical is one of the domestic c-arm manufacturers that have mastered the c-arm 3D imaging technology, and launched the domestic 3D c-arm PLX7500 in 2022, which adopts a large-size dynamic flat panel detector of 30cmx30cm, and is capable of outputting high-resolution, large-size 2D and 3D images. It is worth mentioning that PLX7500 can also be used with orthopedic surgical navigation robot PL300B to complete the positioning of surgical instruments or implants with the assistance of a robotic arm, and the accuracy can reach sub-millimeter level.

How to Perform Special Position Photography with Suspending Digital DR?

图片
  In the rapid development of inspection technology is rapidly changing today, digital DR technology is one of the indispensable inspections in medical imaging department. Digital DR is mainly divided into: bed type, double column type, sickle arm type, suspended digital DR. Among them, the suspended digital DR has a suspended head, the bulb tube can be lifted up and down, and can be along the sky track for horizontal and vertical movement, so that its shooting range is larger compared with other DR, and at the same time, the movement is more flexible. POLYDER Suspended Digital DR is more efficient than conventional X-ray spot filming for complex body positioning photography through rapid fluoroscopic positioning. Suspending Digital DR Suspending Digital DR Specialized Positioning Photography – Weight-bearing Position Non-weight-bearing films in the foot and ankle position can miss deformities in the alignment of bone structures and abnormal changes in the joint cavity.

Exploring the price and cost-effectiveness of spinal surgery robots

图片
  As technology continues to evolve, spinal surgical robots have become an important technology in the medical field. However, the cost of purchasing a spinal surgical robot remains a non-negligible issue for many healthcare organizations. First, let’s look at spine surgery robot prices. According to market research, a spinal surgery robot typically costs between $1 million and $3 million, not including follow-up costs such as installation, maintenance, and training. This price is undoubtedly a huge investment for most healthcare organizations. However, considering the multiple benefits of spinal surgery robots, such as increased success rates, shorter recovery times, and fewer medical errors, this investment seems necessary. Perlove Medical Spine Surgery Robot Next, let’s explore the cost-effectiveness of surgical robots: First , spinal surgery robots can significantly reduce the incidence of medical errors. According to statistics, medical errors caused by human factors account for u

Radiological equipment丨The Solution for Percutaneous Kyphoplasty in Women

图片
  Compression fractures, particularly in women over the age of 66, are a common clinical cause that can greatly impact one’s quality of life. A leading solution for this condition is   percutaneous kyphoplasty , a minimally invasive procedure that has shown remarkable effectiveness in alleviating pain and restoring vertebral height. Perlove Medical, a renowned medical technology company,  offers an innovative robot-assisted percutaneous kyphoplasty solution that has revolutionized treatment outcomes. Understanding the Problem: Compression fractures often occur due to osteoporosis or trauma and can lead to severe pain, reduced mobility, and even disability. Women over the age of 66 are particularly susceptible to these fractures due to age-related bone density loss. Treating this condition promptly is crucial for preventing further complications. The Solution: Perlove Medical  has developed a state-of-the-art robot-assisted percutaneous kyphoplasty solution that addresses key challenges
