Abstract: An imager for simultaneously taking full color pictures and fluorescence images from the same perspectives, top-down and side views, is presented that uses multiple cameras looking at the same stage through a beamsplitter and light sources for each view. The imager is configured to work with a particular fluorophore, or at least a predetermined fluorescence excitation wavelength and emission wavelength. A broadband white light source projects through a shortpass or other filter with a cut-off wavelength either lower than or between the excitation and emission wavelengths. Another shortpass or other filter is in front of a color camera with a cut-off wavelength below that of the emission wavelength, while a monochrome fluorescence camera may or may not have additional filters to bring out the fluorescence. These filters may be built into a dichroic mirror of the beamsplitter. In addition, digital processing may boost frequencies in the color image that were dampened by the filters.

Abstract: Machine-readable media and computer systems are provided for the highlighting of features in composite images through the alternating of images having complementary colors. An image having a feature of interest is used to generate one or more pseudo color images. A series of a pseudo color images and one or more additional pseudo color or original color images are then alternately displayed so that the differently colored regions among the series of images are easily recognizable to an operator. The differently colored regions differ in having hues that are complementary to one another. The methods are particularly useful for the display of information using two or more imaging modalities and channels, such as is the case for some medical applications in which a natural-light image of pink or light-red tissue with deeper red or blue vasculature is overlaid with another functional image.

Abstract: Methods and systems are provided for the detecting and presenting of faint signals from a real-time interactive imager. A real-time view of a subject is controlled by a user by entering commands that move the subject or a camera used to record the real-time view. The rate of this movement is monitored, and when the rate descends below a preset value, a trigger is sent to the camera. In response to the trigger, the camera switches to a lower frame frequency for capturing the real-time view of the subject, thereby increasing the amount of light collected in each frame, and increasing the sensitivity of the camera to faint signals. The methods and systems are particularly relevant for surgical or biopsy imaging, in which both a higher frame rate preview image of a subject for 3D visualization, and a higher sensitivity fluorescence image of the subject for tumor margin assessment, are desired.

Abstract: Methods for determining surgical margins using an imaging device are described that use multiple cameras to image a biological sample on a turntable bathed in white light or fluorescing due to a systemically administered dye. Fluorescence farther away from an excitation light source can be compensated upon determining a 3-D position of portions of the sample. The turntable is turned and tilted in order to take enough images to prepare an animation of the sample. In a graphical user interface, the animation can be stopped, zoomed, and tilted per a user's gesture, touch, tablet-tilting, or other commands. The image manipulation can be with touch gestures entered using a sterilizable or disposable touch pen.

Abstract: Methods and devices are disclosed for the imaging of a biological sample with a top-down camera and a side-view camera. A biological sample is held on an imaging stage that is capable of rotation in two orthogonal axes. The top-down and side-view cameras can record a series of images of the sample using multiple imaging modalities at different rotational positions of the imaging stage. The top-down camera can be translated along its optical axis to affect the camera zoom and influence the resolution and field of view of the recorded images. Fluorescence excitation light sources can be positioned proximate to each of the top-down and side-view cameras to provide substantially uniform illumination of the sample for imaging with each camera.

Abstract: Methods and devices are disclosed for the imaging of a biological sample from all rotational perspectives in three-dimensional space and with multiple imaging modalities. A biological sample is positioned on an imaging stage that is capable of full 360-degree rotation in at least one of two orthogonal axes. Positioned about the stage are imaging modules enabling the recording of a series of images in multiple modalities, including reflected visible light, fluorescence, X-ray, ultrasound, and optical coherence tomography. A computer can use the images to construct three-dimensional models of the sample and to render images of the sample conveying information from one or more imaging channels. The rendered images can be displayed for an operator who can manipulate the images to present additional information or viewing angles of the sample. The image manipulation can be with touch gestures entered using a sterilizable or disposable touch pen.
