This technology includes a method for performing cardiac imaging without the need for the patient to hold their breath. Free breathing pixel-wise myocardial T1 parameter mapping includes performing a free-breathing scan of a cardiac region at a plurality of varying saturation recovery times to acquire a k-space dataset; generating an image dataset based on the k-space dataset; and performing a respiratory motion correction process on the image dataset.

This technology includes part of transcatheter aortic valve replacement and to enable non-surgical thoracic aortic aneurysm endograft repair. The invention enables a completely new way to access the arterial circulation to allow introduction of large devices, such as transcatheter aortic valve replacement, percutaneous left ventricular assist devices, and thoracic aortic endografts. It also can be used in most labeled and off-label applications of Amplatzer (AGA Medical, St Jude) nitinol occluder devices to occlude intracardiac holes and to allow non-surgical direct access to the heart.

This technology includes tools to guide optimization of thermometry imaging/post-processing protocols. Proton Resonance Frequency (PRF) thermometry is a widely used Magnetic Resonance Imaging (MRI) based technique to monitor changes in tissue temperature in response to thermal therapy. The use of PRF thermometry with thermal therapy procedures is indispensable to ensure delivery of desired thermal dose to the target tissue, and to minimize unintended damage to the normal tissue.

This technology includes the use of nanodiamonds to achieve background-free imaging. We present several techniques to reduce or eliminate background florescence by exploiting properties of the fluorescent nanodiamonds. In particular, magnetic field modulation of the fluorescence intensity offers a simple, robust, and easily adaptable method to obtain background free imaging in a variety of imaging modalities, i.e., fluorescence microscopy and wide field fluorescence animal imaging.

This technology includes an electronic method for fringe scanning in grating-based phase-contrast imaging, which enhances x-ray phase-contrast imaging. Traditional methods use high-density gratings and require fine grating fringes, finer than the detector's resolution, necessitating fringe scanning to obtain phase-contrast information. This process typically involves complex and precise movements of a grating for each image, challenging in applications like medical computed tomography that demand rapid gantry rotation and acquisition of numerous projection images in less than a second.

This technology includes a new reagent, termed bivalent Tn5 complex, and applied it to mapping genome-wide enhancer-promoter interactions to be utilized for disease diagnostics. Chromatin structure is critical for regulating transcription in normal development and disease states. In particular, the interaction between enhancers and promotes are essential for the temporospatial control of gene expression.

This technology includes an illuminator and reflector that enables flexible standing wave illumination on an inverted microscope stand, and procedures for using such illumination to improve axial resolution in confocal or instant SIM imaging systems. The axial resolution in conventional fluorescence microscopy is typically limited by diffraction to ~700 nm. This method that improves axial resolution ~7-fold over the diffraction limit, and that can be applied to any fluorescence microscope.

This technology includes algorithms and software that improve the speed of iterative deconvolution, a common method for improving spatial resolution and contrast in fluorescence microscopy images. These algorithms also improve the registration of multiview datasets, and apply deep learning to accelerate spatially varying deconvolution.

This technology includes a number of dimeric RGD peptides which been developed and labeled with various PET isotopes (1BF, 68Ga, and 64Cu) for imaging integrin expression in cancer, inflammation, rheumatoid arthritis, myocardial infarct, stroke and traumatic injury. A number of these peptides have been translated into clinic for diagnosis and therapy response monitoring.

This technology includes ELISA based binding assays of p53, p63 or p73 provide possibilities to validate genome sequencing results, and allow the performance of more in-depth investigation to address scientific mechanisms, as well as to develop applications for high-throughput clinical and diagnosis usages. While quantitative p53 binding assays have been commercially developed, there is a lack of high-throughput method to detect binding activity of all three p53/p63/p73 family members, which are an important step for these transcription factors to perform their function.
