Diagnostic imaging, such as X-rays, computed tomography (CT) scans, and magnetic resonance imaging (MRI), is an essential tool for healthcare professionals to visualize internal structures and diagnose diseases. The demand for diagnostic imaging devices has been on the rise due to the growing geriatric population, increasing cases of chronic diseases, and the need for accurate and timely diagnosis. These devices provide detailed images, aiding in the detection and monitoring of various conditions, including cancer, cardiovascular diseases, and musculoskeletal disorders.
Radiation therapy is another significant application of medical radiation devices. It involves the use of high-energy radiation to destroy cancer cells and shrink tumors. With the increasing incidence of cancer worldwide, radiation therapy has become an integral part of cancer treatment. Medical radiation devices used in radiation therapy include linear accelerators, brachytherapy devices, and proton therapy systems. These devices are designed to deliver precise and targeted radiation doses to cancerous cells while minimizing damage to healthy tissues.
Nuclear medicine is a specialized field that uses radioactive substances to diagnose and treat diseases. Medical radiation devices used in nuclear medicine include gamma cameras, positron emission tomography (PET) scanners, and single-photon emission computed tomography (SPECT) scanners. These devices help in the detection of various conditions, such as heart diseases, neurological disorders, and certain types of cancer. Nuclear medicine procedures are non-invasive and provide valuable information about the functioning of organs and tissues.
The market for medical radiation devices is driven by technological advancements that have improved the accuracy, efficiency, and safety of these devices. For instance, the development of digital imaging technology has revolutionized diagnostic imaging, providing higher resolution images and reducing radiation exposure for patients. Additionally, the integration of artificial intelligence (AI) and machine learning algorithms has enhanced the interpretation of medical images, enabling faster and more accurate diagnoses.
Furthermore, the increasing adoption of minimally invasive procedures and the shift towards outpatient settings have boosted the demand for portable and compact medical radiation devices. These devices offer convenience, flexibility, and cost-effectiveness, allowing healthcare providers to deliver high-quality care in various settings.
However, the market for medical radiation devices also faces challenges. Concerns regarding radiation exposure and its potential risks have raised questions about the safety of these devices. Regulatory bodies and healthcare organizations have implemented guidelines and protocols to ensure the safe use of medical radiation devices and minimize radiation doses.
In conclusion, the market for medical radiation devices is witnessing significant growth due to technological advancements, increasing prevalence of chronic diseases, and the need for accurate diagnosis and treatment options. These devices play a crucial role in diagnostic imaging, radiation therapy, and nuclear medicine, enabling healthcare professionals to provide timely and effective care. With ongoing advancements and innovations, the future of medical radiation devices looks promising, with the potential to further improve patient outcomes and enhance healthcare delivery.
The Shanghai United Imaging Healthcare Co Ltd invention works as follows
A radiation medical device that includes a main support and two imaging assemblies (20) and 30) located at either end of the main support. A patient is moved directly to the other side of the main support after an imaging scan and pathological tissues positioning pictures have been taken. This allows the radiation assembly (30), to perform radiation treatment to improve the efficiency and effectiveness of radiation therapy following the completion of pathological tissues positioning.
Background for Medical radiation device
Radiation therapy is a method of treating disease using radiation rays such as X-rays, electron rays, proton radiatons or other particles generated by various X-ray radiotherapy apparatuses. Radiation therapy is a therapeutic method that uses X-rays to treat diseased tissue. Radiation therapy is used widely in modern medical therapies, such as cancer therapy.
A medical linear accelerator is an example of a particle accelerator that’s commonly used in radiation therapy. A medical linear accelerater includes a head where a radiation source can be arranged to irradiate a diseased tissues.
The treatment head is large in mass because it includes many components, including an accelerating tube and an electron gun. It also has a shielding layer of high density made of lead to prevent extra radiation rays from the radiation source irradiating the body during the operation of the linear acceleration. The linear accelerator also has counterbalance weights that are used to offset the overturning of the treatment head. This results in a large linear accelerator, which is difficult to install, transport, calibrate, or maintain.
An imaging device, such as a CT scanner, will also be needed in conjunction with a linear accelerator during radiation therapy to help position the affected tissue on the body.
The linear accelerator has a large volume, so the patient must be moved a long distance, with a complicated movement. This can easily lead to errors of positioning.
Therefore the problems that need to be solved are how to reduce complexity in a treatment plan, improve the effectiveness of radiation therapy and reduce errors when positioning diseased tissues and irradiating them.
The present disclosure provides a medical radiation apparatus to reduce the complexity of a treatment plan of a radiotherapy and improve the effectiveness of the treatment. It also reduces positioning errors when positioning a tissue that is diseased and applying radiation to the tissue.
The medical radiation apparatus described in the present disclosure is designed to address the problems above. It includes a mainframe, and CT and radiation assemblies that are positioned along the first direction axially. The radiation assembly has a rotating treatment head for emitting radiation.
The main frame may also include a cylindrically-shaped body with openings at both ends, where the central axis is the first axial direction. The treatment head is attached to one end, while the CT assembly is located on the opposite end.
The CT assembly can be mounted on the inner wall of a cylindrical body.
The CT assembly may also include a CT stator that is fixed to the cylindrical body and a CT Rotor mounted onto the CT Stator. The CT Rotor can be rotated around the first axial axis, and both the ray tube, and detector, are mounted on it.
Alternatively, the CT stators is fixed to an inner wall of a cylindrical body and has a mounting hole along the first axial directions; the CT rotor attached via a bearing on the CT stator.
The CT rotor has a through hole defined in the first axial axis, with the ray tube, detector and ray tube positioned on opposite sides. The couch plate can be moved to pass through this through-hole.
Alternatively, the CT stators further include a CT drive mechanism for driving the CT Rotor to rotate. The CT driving mechanisms includes a motor, a driving wheel coupled to a motor and a driving belt between the CT rotor, and the first wheel.
The main frame can also include a base that supports the cylindrical body and is equipped with a roller-driven mechanism to drive the cylindrical body into rotation.
The roller driving mechanism can also include a motor coupled with a driving wheel, and a belt that wraps around the driving wheel.
Alternatively, the mechanism for driving the rollers may also include a guidewheel arranged at the base.
The present disclosure also includes a medical radiography apparatus that includes: a mainframe, which is rotatable around its central axis; a treatment-head, which is connected to the mainframe, and emits radiation rays. An imaging assembly with an imaging-through-hole to image an item located in the imaging-through-hole.
Alternatively, the mainframe includes a cylinder body substantially coaxial to the imaging through hole.
Alternatively, the medical radiography apparatus further comprises a rotor on which the imaging assembly has been mounted, which is connected to the mainframe and rotates with the mainframe.
