Abstract: Aspects of the present disclosure provide a quick actions menu in an artificial reality (XR) environment that can be accessed by performing a hand gesture detected by an XR device which, in some implementations, can be detected without the use of controllers. Once the menu is open, the user can move her hand while performing the gesture to highlight a particular quick action and can release the gesture on a highlighted action to select the action. In some implementations, the user can drill down into an action on the menu by highlighting the action, then dragging the gesture off of the action away from the menu. To close the quick actions menu, the user can either A) move the gesture off the menu and release the gesture, B) rotate the wrist, or C) explicitly dismiss the menu, such as by using a voice command detected by the XR device.

Abstract: Systems and methods are provided for lesion depth determination in molecular breast imaging. The depth of a lesion in a breast of a subject may be determined during a molecular breast imaging (“MBI”) procedure where the resolving power of the detectors, such as gamma cameras, that degrades with distance from the face of the detector is exploited. By comparing the apparent size of a lesion in two opposing detectors, it is possible to estimate the distance of the lesion from each detector by modeling or measuring the resolution that changes with distance from the detectors. The systems and methods may be used during biopsy procedures to indicate the appropriate needle depth for biopsy of the lesion.

Abstract: Aspects of the present disclosure are directed to artificial reality (XR) controllers and hand gestures and corresponding representation of the hand gestures in XR space. Users can benefit from being able to use touch interactions while also holding the XR controller. Example implementations allow a user to use controllers for distance interaction and interactions that require controller buttons, but also recognize when the user extends her finger and wants to manually touch things-using touch in conjunction with controllers. Thus, if the user has a controller in her hand and want to touch a UI element, she can also use her finger, where the system identifies the finger not touching the controller (e.g., via capacitance sensors) and that a hand pose is present (e.g., finger extended—from camera) to allow that finger to provide hand input, without the user having to put down the controller.

The simulation application simulates the fluid flow associated with each fine voxel in the plurality of fine voxels at the second resolution based at least in part on the simulation at the coarse resolution.

The quantification is effectuated based on comparison a first photon count (determined from an MBI image of a region of interest encompassing both the tumor and background tissue of the sample) and a second photon count (determined from an MBI image of a region of a substantially co-extensive region of interest that encompasses only background tissue and is devoid of tumor), and based on the values of depth of tumor and its size determined from the ultrasound imaging data.

Abstract: A system and method for performing quantitative lesion analysis in molecular breast imaging (MBI) using the opposing images of a slightly compressed breast that are obtained from the dual-head gamma camera. The method uses the shape of the pixel intensity profiles through each tumor to determine tumor diameter. Also, the method uses a thickness of the compressed breast and the attenuation of gamma rays in soft tissue to determine the depth of the tumor from the collimator face of the detector head. Further still, the method uses the measured tumor diameter and measurements of counts in the tumor and background breast region to determine relative radiotracer uptake or tumor-to-background ratio (T/B ratio).
