The primary objective of this clinical trial is to assess the influence of orthognathic surgery on facial soft tissue, such as changes (volume, linear, angular) of facial hard and soft tissue, in three dimensions, so enabling the setup of 3D normative value tables.
Allocation: Non-Randomized, Control: Uncontrolled, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Diagnostic
3D stereophotogrammetric imaging, 3D CT-imaging with cone-beam CT, Case report form

Cone beam computed tomography (CBCT), is a recent medical imaging technique where the X-rays are divergent, forming a cone. As a result, this technique is less irradiating that the scanne...
The investigators will assess the feasibility of intraoperative use of C-arm cone-beam CT imaging for intraoperative dosimetric evaluation in prostate low-dose-rate (LDR) brachytherapy. Pa...
To study changes in tumor and normal organ size and/or position which occur during a course of radiation treatments.
To evaluate the use of cone beam computed tomography in treating head and neck to hopefully reduce side effects
The purpose of this study is to test a new technology for obtaining x-ray images of your treatment fields when you are positioned on the treatment machine, to determine whether this new sy...
To compare the use of cone-beam computed tomography versus contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) in the calculation of liver volume and planned dose for yttri...
The simple bone cyst (SBC) is a benign intraosseous lesion that is considered to be a pseudocyst because the cystic cavity does not present an epithelial lining. The most accepted theory regarding its...
Pancreatic hamartoma is a rare benign malformation that resembles a neoplasm and may be mistaken for a malignancy. The imaging findings of pancreatic hamartoma are not well established, as only one ra...
Knowledge of the imaging doses delivered to patients and accurate dosimetry of the radiation to organs from various imaging procedures is becoming increasingly important for clinicians. The purposes o...
We report a case of a 58-year-old male diagnosed with myofibroblastoma using mammography, ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI), as well as present a review of the ...
The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.
Timing the acquisition of imaging data to specific points in the breathing cycle to minimize image blurring and other motion artifacts. The images are used diagnostically and also interventionally to coordinate radiation treatment beam on/off cycles to protect healthy tissues when they move into the beam field during different times in the breathing cycle.
The use of combination of imaging techniques or platforms (e.g., MRI SCAN and PET SCAN) encompassing aspects of anatomical, functional, or molecular imaging methods.
A technetium imaging agent used in renal scintigraphy, computed tomography, lung ventilation imaging, gastrointestinal scintigraphy, and many other procedures which employ radionuclide imaging agents.
Optical imaging techniques used for recording patterns of electrical activity in tissues by monitoring transmembrane potentials via FLUORESCENCE imaging with voltage-sensitive fluorescent dyes.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
