Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of desktop DR, and more specifically, to a desktop DR device. Background Art
[0002] Digital radiology is an advanced imaging technology used in medical diagnosis and treatment. It uses X-rays to penetrate an object and produce two-dimensional images, aiding in the diagnosis and treatment of various diseases and injuries. It is suitable for routine health examinations, such as those involving teeth, internal organs, and bones. A tomotherapy system (TOMO) rotates the sample to capture multiple projection images from different angles. Computer processing reconstructs the sample's three-dimensional structure, providing detailed 3D image information for visualizing internal structures and radiotherapy. The medical market is rapidly developing, and digital radiotherapy has garnered widespread attention. Imaging is a crucial basis for diagnosis and treatment. Commercially available DRs (DRs) come in a variety of sizes and specifications, and clinical diagnostics require different sizes for different examination subjects. A single DR size cannot simultaneously capture images of the oral cavity and other body parts, forcing clinics to purchase multiple DRs or larger DRs with a wider imaging range, which are expensive. Some surgical procedures require 3D visualization of internal structures. Existing DRs cannot provide this 3D information, requiring the purchase of a TOMO or CT scan. Space constraints and cost constraints are major challenges in implementing digital radiotherapy. Furthermore, adjusting the position and angle of the subject to be imaged is inconvenient. To address this issue, a desktop DR device has been proposed. Utility Model Content
