Stanford researchers have patented the use of a coherent frequency-domain technique in microwave thermoacoustic imaging, which significantly improves signal-to-noise ratio (SNR) and reduces peak-power requirements without sacrificing resolution or other performance metrics.
Several linear accelerator vendors have systems with single x-ray imager. A single x-ray imager presents a challenge to estimate 3D positioning. A method to estimate the 3D position using a single x-ray imager with prior information has been developed by Stanford researchers.
Stanford researchers have developed a novel method for the quantification of person-level network functioning, enabling the diagnosis of depression and suggesting an appropriate treatment.
In the presence of intra-fraction organ motion, target localization uncertainty can hamper the advantage of using highly conformal dose techniques such as intensity modulated radiation therapy (IMRT).
Stanford Researchers have patented a method and apparatus for detecting ionizing radiation, that, if successful, would achieve a coincidence time resolution 100x better than current positron emission tomography (PET) detectors.
Stanford researchers developed an ultrasound method to estimate the local speed of sound of tissue, regardless of the tissue overlying the target location.
Stanford researchers at the Rao Lab have developed apoptosis imaging probes with an improved new molecular structure enabling high sensitivity and stability with better performance in vivo.
An interdisciplinary team of Stanford researchers is developing a dual axis confocal (“DAC”) microscope system for in vivo imaging of tissues at the cellular scale.
MR-guidance for biopsy procedures features high intrinsic soft-tissue contrast. However, artifacts induced by the metallic needle such as signal void and distortions can reduce the localization of the needle and thus prevent the targeting of smaller lesions.
Researchers at the Solgaard Lab have demonstrated that light sheet fluorescence microscopy (LSFM) with structured and pivoting illumination enables fast image acquisition and improved image quality.
Stanford researchers have invented a decoder for multiplexed readouts of imaging arrays that optimizes the signal-to-noise ratio (SNR) of the decoded detector pixel signals.
Stage of research
Researchers designed electro-optical gratings for fluorescence microscopy - a drop in to existing systems with no new lenses. Researchers demonstrate a 9x improvement on FOV using Olympus 10x/0.6NA WI immersion objective at 3.3 Hz.
A volumetric computed tomography method includes translating a discrete element x-ray source and detector relative to the patient or object in a z-direction parallel to the axis of rotation.
Researchers in the Molecular Imaging Instrumentation Laboratory at Stanford University have developed methods to improve the image quality of tomographic image reconstruction, including positron emission tomography (PET).
