Systems, methods, and media for presenting medical imaging data in an interactive virtual environment reality are provided. In some embodiments, a system comprises a head mounted display (HMD) that: determines that a transparent 3D object overlaps a 3D model of a portion of anatomy based on a medical imaging scan; sets values for pixels corresponding to portions of the 3D model not occluded by the transparent object by performing a shading operation; sets values for pixels corresponding to portions of the 3D model at the boundary of the transparent object to intensity values taken from the medical imaging data; displays the 3D model with an exterior surface shaded to evoke a 3D object, and internal surfaces at the boundaries of the transparent object not shaded to preserve details embedded in the medical imaging data.

There is provided a lung simulation apparatus for simulating a state of a living mammalian lung, the lung simulation apparatus comprising, a housing having a shape defined by an apex, an open base and a lateral surface that tapers from the open base to the apex; an elastic membrane covering the open base of the housing; an inflatable sac disposed within the housing, the sac being in substantial conformance with the shape of the housing and approximating the shape of the living mammalian lung, when in an inflated state; an internal space for containing fluid, the internal space being defined as the space between the housing and the inflatable sac and the space between the elastic membrane and the inflatable sac, wherein the space for containing fluid substantially complies with the anatomical dimensions of an intrapleural space of the living mammalian lung when the inflatable sac is in the inflated state. There is also provided a method of making the lung simulation apparatus.

An imaging conditions acquisition unit acquires imaging conditions relevant to the positioning of an irradiation device and a radiation detector for acquiring a medical image. An imaging control unit controls the irradiation device and the like so as to acquire a pre-shot image or the medical image of the subject. A correction amount calculation unit calculates the correction amount of the imaging conditions based on the pre-shot image. A notification unit sends notification of the correction amount.

Disclosed are systems and methods for providing virtual reality guidance to a user performing a procedure on a virtual instance of an item. The systems and methods may be used in training the user to perform the procedure on a physical instance of the item.

A method and apparatus for performing a contrast simulation of a CT or MRI scan is disclosed. Voxel(s) within a three-dimensional dataset are modified using an artificial intelligence algorithm to generate a virtual contrast three-dimensional dataset. The modification includes altering the numerical value(s) of voxels corresponding to body tissue(s) in accordance with said blood flow through said body tissue, such that an appearance of contrast is created. Multi-phase simulations can be performed to track contrast flow through the vascular tree. Some embodiments comprise inserting virtual contrast in conjunction with performing a deformity of the vascular structure.

The current invention relates to data flow of video streaming, to user instructions' transfer between two computing devices over the internet and to a man machine interface in which a feedback is provided relating to the quality of such interactions and related video products. The invention introduces new ways to improve video streaming quality and to train users for the purpose of achieving better results of video capturing.

A multi-modality fatty tissue mimicking material for phantoms for use with thermoacoustic imaging, ultrasound imaging and magnetic resonance imaging, which includes: an aqueous mixture of a 3% to 18% thickening agent, a 1% to 30% protein powder, a 0.1% to 2% ionic salt, a 30% to 85% water, and a 0% to 60% oil by weight, wherein the oil percentage corresponds to the fat percentage in tissue, further wherein the ionic salt percentage corresponds to an imaginary part of complex permittivity in tissue, and further wherein the water, oil and protein powder percentages correspond to the real part of complex permittivity in tissue.

A surgical simulation device is disclosed that allows a structural heart disease (SHD) team, including a surgeon and an imaging specialist to perform a simulated cardiac intervention procedure using a patient-specific model that replicates biomechanical and echogenic properties of a specific patient to be operated on. The surgical simulation device can include a station with a tank for receiving a patient-specific cartridge with the patient-specific model. The device can also include an esophageal access system in the station and a vascular access system that couples to an access port of the station.

The present invention relates to an eye phantom for evaluating a retinal angiography image, and a manufacturing method therefor. A purpose of the present invention is to provide an eye phantom for evaluating a retinal angiography image, capable of simulating even the vascular structure and blood flow of a retina so as to be more similar to an actual retinal structure than a conventional eye phantom; and a manufacturing method therefor. More specifically, a purpose of the present invention is to provide an eye phantom for evaluating a retinal angiography image, including various shapes of fine fluid channel structures corresponding to the vascular structure formed in an actual retina; and a manufacturing method therefor.
