What are the large medical imaging equipment After-sales maintenance?


From the market level, medical imaging equipment is the largest component of the global medical equipment market, and has been growing steadily in recent years.

Agency data show that the global medical imaging equipment market size has increased from $58 billion in 2017 to $70.4 billion in 2021, with a compound annual growth rate of 4.9%, and is expected to increase to $84.3 billion by 2026, with a compound annual growth rate of 3.7%.

The development of China’s medical imaging equipment market is even more rapid, with the market size increasing from $65.5 billion in 2017 to $95.4 billion in 2021, at a CAGR of 9.8%, and is expected to increase to $148.6 billion by 2026, at a CAGR of 9.3%.

Medical imaging equipment mostly belongs to large instruments, do you know what kinds of large medical imaging equipment?

(A) X-ray imaging class (CR, DR, DSA, etc.): according to the principle that there are differences in the degree of absorption of X-rays by different tissues of the human body for imaging.

① CR, Computed Radiography, the imaging plate as a carrier, the X-ray exposure and information read out after processing to form a digital image of an X-ray photographic technology.

DR, Digital Radiography, flat panel detector, charge-coupled device (CCD), etc. as a conversion medium, the illuminated body information in the form of digital image transmission of an X-ray photographic technology.

DSA, digital subtraction angiography, an X-ray imaging technology that combines computerized image processing technology with conventional angiography. A subtraction image that removes bones, muscles, and other soft tissues for a purely vascular image is obtained by a computerized image processing system.

X-ray images can visualize the morphology related to the bones and organs of the human body, showing overlapping images of the internal organs of the human body.

(ii) ComputedTomography (CT)

With the same principle of X-ray imaging, CT and X-ray imaging is the biggest difference between the use of precise collimation of X-ray beams, y-rays, ultrasound, etc., and the sensitivity of the detector around a part of the human body for a cross-section scanning, and through the computer system to form the final gray-scale image.

(C) Magnetic resonance imaging (Magnetic resonance imaging, MRI): the use of static magnetic fields and radiofrequency magnetic fields to make human tissue imaging.

The high proportion of water in the human body is the basis for the widespread use of magnetic resonance imaging technology, MRI is mainly on the magnetic resonance effect of the hydrogen nucleus imaging, the pathological process of many diseases will lead to changes in the shape of the water, which can be reflected by the magnetic resonance image.

(D) nuclear medicine imaging (nuclear medicine imaging): according to the principle of radiation tomography imaging.

Common PET/CT, PET/MR (PET, positron emission tomography, Positron emission tomography).

Nuclear medicine images are functional images that do not depend on changes in the density of the tissue, but on factors such as blood flow to the organ or tissue, cellular function, cell number, metabolic activity, and excretion and drainage.

The subject takes the tracer with isotope labeling, and after metabolism, the image signal reflects the distribution of isotope concentration in different parts of the body, showing morphological and functional information.

Since changes in functional metabolism often occur before morphological changes in the course of lesions, nuclear medicine imaging is mostly used in the diagnosis of cancer and other diseases, and has early diagnostic value.

The main difference between nuclear medicine imaging and other radiologic examinations is that nuclear medicine imaging evaluates organ function, whereas other imaging methods evaluate anatomical structure (organ appearance).

In addition to this, ultrasound imaging equipment and medical endoscopes are not considered to be large-scale medical imaging equipment.

After-sales maintenance of large medical equipment should not be ignored.

Generally speaking, a tertiary hospital with a total value of 200 million dollars of medical equipment needs to spend about 2 to 6 million dollars a year on total maintenance costs. And the imaging department’s equipment maintenance costs account for more than 50% of the hospital’s total maintenance expenditures, most of which come from large medical equipment, the replacement of spare parts is as little as a few tens of thousands of dollars, hundreds of thousands of dollars, or nearly a million.

Therefore, hospitals in the procurement of large medical equipment
