Equipments

X-ray RADspeed Pro style edition GLIDE Class (Shimadzu) and 2 other models FPD type X-ray systems for standing and supine X-ray scanning. It enables high image quality imaging at a low dose, and at our hospital, imaging is performed at a dose lower than the 75% standard value of DRL (Diagnostic Reference Level).
3.0T-MRI Skyra (Siemens) The 3.0T-MRI Skyra (Siemens) is equipped with state-of-the-art technologies such as a high magnetic field magnet, TrueForm, and a patient-friendly wide bore. Provides high image quality. 詳細はこちら
1.5T-MRI MAGNETOM Altea (Siemens) The power of the magnet enables tomographic imaging of the entire body. It is also powerful in detecting cerebral aneurysms because it can depict blood vessels without the use of contrast media. At our hospital, we have two units of 3.0T-MRI for examination.
80-row X-ray CT Aquilion Helios (Cannon Medical) This CT system is equipped with the latest technologies such as short scanning time, reduced radiation exposure, and elimination of metal artifacts. In addition, the Zio Station 2 workstation can be used to instantly create 3D cerebrovascular images and virtual bronchoscopes. Click here for details.
64-row X-ray CT system SOMATOM Sensation (Siemens) The high speed rotation of 0.33 seconds per rotation enables whole body imaging in a short time. It is especially effective in cardiac examinations, which are vulnerable to movement. We have three CT systems: two 64-row CT systems and one 80-row CT system. Click here for details.
Angiography Allura Clarity (Philips) This is a general-purpose biplane (two-tube) DSA. We provide endovascular treatment of the entire body from head to toe. Click here for details.
Angiography Azurion7 F20 (Philips) Integrates clinical excellence and workflow innovation to improve performance in cardiac diagnostics and a wide range of treatments. It also allows for easy and confident treatment of a wide variety of procedures. Minimizes risk, simplifies setup, and increases efficiency and flexibility. Provides high quality care to patients with live image guidance functions that support advanced diagnosis and treatment.
X-ray TV ZEXIRA (Cannon Medical) Performs all types of fluoroscopic examinations, including upper and lower gastrointestinal tract, urology, gynecology, orthopedics, etc. Equipped with a 17-inch large-field FPD, it provides high-resolution images at low dose.
Nuclear Medicine Examination Symbia Evo Excel (Siemens) RI (radioisotope), which emits minute amounts of radiation, is administered to examine the brain (blood flow and cognitive function), myocardial blood flow, bone lesions, etc. Click here for details.
Bone Densitometry Discovery (Holologic) Bone density of the lumbar spine and hip joint is measured for the diagnosis of osteoporosis. In addition to the frontal view of the lumbar spine, it can also be used for the lateral view, providing more accurate data.
Mammography MAMMOMAT Revelation The top-of-the-line model for screening and close examination. The MAMMOMAT Revelation is a top-of-the-line mammography system for screening and close examination. The MAMMOMAT Revelation is a state-of-the-art device that makes a new difference in mammography in terms of diagnostic capability. Five female technologists are in charge of imaging.
