Description
Technical Field
The invention relates to the technical field of beauty manufacturing, in particular to a method for customizing a personalized silica gel prosthesis mould based on MRI (magnetic resonance imaging) image data.
Background
MRI Magnetic Resonance Imaging (MRI) is a medical Imaging technique based on the principle of Nuclear Magnetic Resonance (NMR), and forms an image of a human anatomy or physiological process using a Magnetic field and radio frequency waves. In humans and other biological organisms, hydrogen atoms are abundant and are most commonly used for detection. The MRI examination procedure is as follows: the radio wave pulses excite hydrogen atoms in the magnetic field, which generate energy transitions that emit radio frequency signals that are received by antennas located around the organ to be examined, which are processed to form images. MRI spatially localizes the signals through magnetic field gradients; by varying the pulse sequence parameters, different signal intensities are produced between different tissues, resulting in image contrast. Hydrogen atoms are particularly abundant in water and fat, and therefore, most magnetic resonance images can be considered to map the distribution of water and fat in vivo. The magnetic resonance imaging room where MRI is located is affiliated to the hospital radiology department. MRI involves no ionizing radiation, which is the largest place to distinguish from Computed Tomography (CT), computer aided test scan (CAT scan), and Positron Emission Tomography (PET) imaging modalities. In contrast to CT, MRI allows the body to be protected from ionizing radiation and yields a variety of information. While X-rays can be well controlled in most medical environments today, MRI is still considered a better choice than CT. Magnetic resonance scanning may also present risks and discomfort. MRI is typically longer, noisier, and generally requires the subject to enter a narrow, confined duct, as compared to CT. In addition, patients with certain medical implants or other non-removable metals in their body cannot be examined by magnetic resonance. Magnetic Resonance Imaging was originally referred to as Nuclear Magnetic Resonance Imaging (NMRI), but the "Nuclear" word is omitted to avoid negative associations. [1] Since the 70, 80's of the 20 th century, MRI has been continuously developed and now proven to be a multifunctional imaging technique widely used for diagnosis, staging, prognosis and patient follow-up of diseases. Although magnetic resonance imaging finds application primarily in medical diagnostics and biomedical research, it may also be used for imaging non-biological objects. In addition to detailed spatial images, magnetic resonance imaging is capable of producing a variety of chemical and physical data. However, the continuing growth in the demand for magnetic resonance imaging has led to cost-effective and over-diagnostic concerns for healthcare systems.
The silica gel prosthesis is short for silica gel prosthesis, the capsule wall of the silica gel prosthesis is elastomer silicon rubber, and the content filled in the capsule is silica gel. Silica gels have been used for over 50 years in various applications in daily life and medicine. During the years of breast augmentation, a variety of materials have been used for breast augmentation, and in summary of the superiority and inferiority of various prosthetic materials, silicone gel prostheses are relatively cost effective breast augmentation materials.
The customized silica gel breast prosthesis can not only meet the actual requirements of wearers, but also become one of the problems to be solved in the aspects of modern medicine and plastic. It is very important to improve the quality of life and solve the problems of physiology, psychology and family.
