• An endoscope is an illuminated optical, typically slender and tubular instrument (a type of borescope) used to look within the body.
• An endoscope may be used to examine internal organs for diagnostic or surgical purposes. Specialized instruments are named after their target anatomy, e.g., the cystoscope (bladder), nephroscope (kidney), bronchoscope (bronchus), arthroscope (joints), colonoscope (colon), laparoscope (abdomen or pelvis).
• Laparoscopic surgery is commonly performed in the abdomen or pelvis using small incisions (usually 0.5-1.5 cm) with the aid of a laparoscope.
• small incisions usually 0.5-1.5 cm
• the advantages of such minimally invasive techniques are well-known, and include reduced pain due to smaller incisions, less hemorrhaging, and shorter recovery time as compared to open surgery.
• a laparoscope may be equipped to provide a two-dimensional, image, a stereo image, or a depth field image (as described further below).
• Robotic surgery is similar to laparoscopic surgery insofar as it also uses small incisions, a camera and surgical instruments. However, instead of holding and manipulating the surgical instruments directly, a surgeon uses controls to remotely manipulate the robot.
• a console provides the surgeon with high-definition images, which allow for increased accuracy and vision.
• An image console can provide three-dimensional, high definition, and magnified images.
• Various electronic tools may be applied to further aid surgeons. These include visual magnification (e.g., the use of a large viewing screen that improves visibility) and stabilization (e.g., electromechanical damping of vibrations due to machinery or shaky human hands).
• Simulator may also be provided, in the form of specialized virtual reality training tools to improve physicians' proficiency in surgery.
• a depth field camera may be used to collect a depth field at the same time as an image.
• An example of a depth field camera is a plenoptic camera that uses an array of micro lenses placed in front of an otherwise conventional image sensor to sense intensity, color, and distance information.
• Multi-camera arrays are another type of light- field camera.
• the standard plenoptic camera is a standardized mathematical model used by researchers to compare different types of plenoptic (or light-field) cameras.
• the standard plenoptic camera has microlenses placed one focal length away from the image plane of a sensor. Research has shown that its maximum baseline is confined to the main lens entrance pupil size which proves to be small compared to stereoscopic setups. This implies that the standard plenoptic camera may be intended for close range applications as it exhibits increased depth resolution at very close distances that can be metrically predicted based on the camera's parameters.
• plenoptic cameras may be used, such as focused plenoptic cameras, coded aperture cameras, and/or stereo with plenoptic cameras.

• a structured light source e.g., a projector
• the pattern of lines produces a line of illumination that appears distorted from other perspectives than that of the source and these lines can be used for geometric reconstruction of the surface shape, thus providing positional information about the surface of the object.
• range imaging may be used with the systems and methods described herein to determine positional and/or depth information of a scene, for example, using a range camera.
• one or more time-of-flight (ToF) sensors may be used.
• the time-of-flight sensor may be a flash LIDAR sensor.
• the time-of-flight sensor emits a very short infrared light pulse and each pixel of the camera sensor measures the return time.
• the time-of-flight sensor can measure depth of a scene in a single shot.
• a 3D time-of-flight laser radar includes a fast gating intensified charge-coupled device (CCD) camera configured to achieve sub-millimeter depth resolution.
• CCD charge-coupled device
• a short laser pulse may illuminate a scene, and the intensified CCD camera opens its high speed shutter.
• the high speed shutter may be open only for a few hundred picoseconds.
• 3D ToF information may be calculated from a 2D image series which was gathered with increasing delay between the laser pulse and the shutter opening.
• various types of signals are used with ToF, such as, for example, sound and/or light.
• using light sensors as a carrier may combine speed, range, low weight, and eye-safety.
• infrared light may provide for less signal disturbance and easier distinction from natural ambient light, resulting in higher-performing sensors for a given size and weight.
• ultrasonic sensors may be used for determining the proximity of objects (reflectors).
• a distance of the nearest reflector may be determined using the speed of sound in air and the emitted pulse and echo arrival times.
• an image console can provide a limited three-dimensional image based on stereo imaging or based on a depth field camera, a basic stereo or depth field view does not provide comprehensive spatial awareness for the surgeon.

• each pixel is paired with corresponding depth information.
• each pixel of the digital image is associated with a point in three-dimensional space.
• the pixel value of the pixels of the digital image may then be used to define a point cloud in space.
• Such a point cloud may then be rendered using techniques known in the art. Once a point cloud is defined, it may be rendered from multiple vantage points in addition to the original vantage of the camera. Accordingly, a physician may then rotate, zoom, or otherwise change a synthetic view of the underlying anatomy. For example, a synthetic sideview may be rendered, allowing the surgeon to obtain more robust positional awareness than with a conventional direct view.

• a PACS is not limited to a predetermined list of images, and supports clinical areas beyond conventional sources of imaging such as radiology, cardiology, oncology, or gastroenterology.
• Different users may have a different view into the overall PACS system. For example, while a radiologist may typically access a viewing station, a technologist may typically access a QA workstation.
• the PACS Gateway 811 comprises a quality assurance (QA) workstation.
• the QA workstation provides a checkpoint to make sure patient demographics are correct as well as other important attributes of a study. If the study information is correct the images are passed to the archive 812 for storage.
• the central storage device, archive 812 stores images and in some implementations, reports, measurements and other information that resides with the images.
• images may be accessed from reading workstations 821...829.
• the reading workstation is where a radiologist reviews the patient's study and formulates their diagnosis.
• a reporting package is tied to the reading workstation to assist the radiologist with dictating a final report.
• a variety of reporting systems may be integrated with the PACS, including those that rely upon traditional dictation.
• CD or DVD authoring software is included in workstations 821...829 to burn patient studies for distribution to patients or referring physicians.

• DICOM Communications in Medicine
• the communication protocol is an application protocol that uses TCP/IP to communicate between systems. DICOM files can be exchanged between two entities that are capable of receiving image and patient data in DICOM format.
• DICOM groups information into data sets. For example, a file containing a particular image, generally contains a patient ID within the file, so that the image can never be separated from this information by mistake.
• a DICOM data object consists of a number of attributes, including items such as name and patient ID, as well as a special attribute containing the image pixel data. Thus, the main object has no header as such, but instead comprises a list of attributes, including the pixel data.
• a DICOM object containing pixel data may correspond to a single image, or may contain multiple frames, allowing storage of cine loops or other multi-frame data. DICOM supports three- or four-dimensional data encapsulated in a single DICOM object. Pixel data may be compressed using a variety of standards, including JPEG, Lossless JPEG, JPEG 2000, and Run-length encoding (RLE). LZW (zip) compression may be used for the whole data set or just the pixel data.
