Neutron imaging: Detection of cancer using animal model

Abstract: Imaging modalities for cancer detection include X-ray, computed tomography, magnetic resonance imaging, ultrasound, positron emission tomography, and optical imaging. Each imaging technology has advantages and disadvantages with limitations either in spatial resolution or sensitivity for cancer detection. Hydrogen nuclei scatter cold neutrons stronger than any other atomic nuclei; therefore hydrogen is a primary contributor to neutron contrast in biological specimens. Neutron imaging for cancer research is an emerging and highly innovative tool that has been intensively exploring over the past three years at the Oak Ridge National Laboratory. Spontaneous cancers in companion animals offer unique models for human cancer biology. We have demonstrated the uniqueness of neutron radiography to objectively detect tumors from surrounding normal lung tissues at an unprecedented spatial resolution of approximately 100 μm. The neutron images of cancer were correlated and matched with histology data. Neutron imaging has the potential to non-destructively provide complementary information about the structure of cancers in biospecimens.

Technique of Magnetic Resonance Imaging Assisted Simulation Based on Direct Coronal Imaging for Treatment Planning of Supradiaphragmatic Malignant Lymphoma

Abstract: In radiotherapy of malignant lymphoma radiotherapy has been delivered using opposed AP/PA large fields on linear accelerators for more than 20 years (Hoppe 1987; Wannenmacher et al. 1978). A basic precondition for treatment planning has always been the adequate localization of lymphoma, lymph node bearing areas, and organs at risk, which may have to be shielded by individual blocking. The procedure of localization is performed based on clinical, pathological, and imaging information. As imaging technology has evolved dramatically during the past two decades with the introduction of computed tomography (CT), ultrasound, digital subtraction angiography, and magnetic resonance imaging (MRI), the role of imaging has changed — becoming the most important tool in the localization procedure for malignant lymphoma nowadays. Nevertheless, the most widespread basic procedure for treatment planning in malignant lymphoma remains fluoroscopic imaging on the therapy simulator (Hoppe 1987; Timothy et al. 1989; Wannenmacher et al. 1978). Tumor, target volume, and organs at risk are defined on the X-ray simulation film based on information about the localization of tumor and target which must be “translated” from transverse cross-sectional, parallel projected imaging (mostly CT) onto the centrally projected coronal X-ray images, the simulation films. This rather complicated translation procedure entails many uncertainties, in particular a considerable risk of mislocalization.

Microscopic thermal imaging method

Abstract: The invention discloses a microscopic thermal imaging method Firstly four low-resolution undersampling micro-scanning images of an object are acquired; then four standard 2x2 uniform micro-scanning undersampling images are acquired according to the four low-resolution undersampling micro-scanning images; and finally a high-resolution oversampling thermal image is acquired by cross merging of the four standard 2x2 uniform micro-scanning undersampling images The microscopic thermal imaging method aims at a problem that ideal micro-scanning position points with respective shortage of half pixel cannot be obtained due to influence of factors of environment, mechanical vibration, device processing precision and other factors, and the high-resolution oversampling image is obtained by utilizing the low-resolution undersampling micro-scanning images through practical acquisition so that the ideal micro-scanning position points can be obtained The microscopic thermal imaging method can be completed only by algebraic operation so that the microscopic thermal imaging method is simple, rapid and stable, imaging quality is enhanced and application and popularization of the optical micro-scanning microscopic thermal imaging technology in all fields can be facilitated

Current status of optical coherence tomography.

Abstract: Optical coherence tomography (OCT) is a novel imaging technology based on low-coherence interferometry that use near-infrared light in real-time, and allows cross-sectional in-situ visualization of the vessel wall at the microscopic level OCT provides 10-fold higher resolution than intravascular ultrasound which is currently the most used modality for intra-coronary imaging OCT offers the obvious advantages when characterizing precise plaque microstructure and distinguishing various type of plaques OCT is also being assessed for its potential role in the understanding of neointimal coverage, vascular healing and the progression of atherosclerosis in coronary vasculature after stenting on the micron scale These unique capabilities could be helpful in guiding coronary management and interventions Recent improvement in next generation OCT technology, such as frequency-domain OCT, will allow for a simple imaging procedure, providing more useful information and complementing other modalities on both clinical and research applications for the cardiologists
