Technical note: mobile CT scanner gantry for use in the operating room.
In modern neurosurgical practice, CT is a well established, important examination for planning surgery and perioperative care. Recently, CT scanners have been used for intraoperative imaging during craniotomy [1-6]. In this paper, we report a newly developed mobile CT scanner gantry with a modified fork-lift gantry carrier. This system enables the radiologist to obtain CT images during surgery ...
متن کاملDesigning and developing an in-house CCD based optical CT scanner for gel dosimetry
Introduction: Measurement of the complex 3D radiation dose distribution created with advanced radiotherapy techniques such as IMRT and SRS became very important. Polymer gel dosimetry (PGD) is proposed method to recording this dose distribution. MRI, X-ray CT, ultrasound, spectrophotometry and optical CT scanners can be used for readout of Polymer gel dosimeters. Although MRI i...
متن کاملUse of a clinical PET/CT scanner for whole body biodistribution of intranasal nanoparticles
Whole body biodistribution of 100 nanometer sized polymer micellar nanoparticles (NPs) was determined following intranasal administration using PET/CT imaging on a clinical scanner. Nanoparticles labeled with Zirconium 89 were administered intranasally or intravenously to Sprague Dawley rats followed by serial ex vivo PET/CT imaging in a clinical scanner. At 30 minutes and 1 hour following intr...
متن کاملToward a Flexible and Portable CT Scanner
The very hot and power-hungry x-ray filaments in today's computed tomography (CT) scanners constrain their design to be big and stationary. What if we built a CT scanner that could be deployed at the scene of a car accident to acquire tomographic images before moving the victim? Recent developments in nanotechnology have shown that carbon nanotubes can produce x-rays at room temperature, and wi...
متن کاملPET/CT scanner instrumentation, challenges, and solutions.
PET/CT scanners offer a hardware solution for aligning and viewing functional and anatomic images that is immune to many of the errors in strictly software registration techniques. Moreover, PET attenuation-corrected emission scans benefit from the use of the onboard CT for fast, low-noise attenuation correction. Along with the significant improved localization and reduced acquisition time, PET...
