Digital Autopsy
A digital autopsy is a non-invasive autopsy in which digital imaging technology, such as with CT scan, computerized tomography (CT) or magnetic resonance imaging (MRI) scans, is used to develop three-dimensional images for a virtual exploration of a human body. Digital autopsy, simply, means conducting autopsy in computerized environment by digital tools. The first step of digitizing starts with the medical imaging modalities that provide the raw data images from the deceased. The most common modalities are CT scan, computerized tomography (CT scan) and magnetic resonance imaging (MRI) scanner. Three dimensional medical visualization is the technical process that provide the digital environment for exploration of the 3D body and conducting the digital autopsy. The term cannot be found before 1985 in the literature. However, there are many other similar terms like: Postmortem CT scanning for individual organs, volumetric radiologic scanning, Virtual Autopsy and Virtopsy. History ...

Autopsy
An autopsy (post-mortem examination, obduction, necropsy, or autopsia cadaverum) is a surgical procedure that consists of a thorough examination of a corpse by dissection to determine the cause, mode, and manner of death or to evaluate any disease or injury that may be present for research or educational purposes. (The term "necropsy" is generally reserved for non-human animals). Autopsies are usually performed by a specialized medical doctor called a pathologist. In most cases, a medical examiner or coroner can determine the cause of death. However, only a small portion of deaths require an autopsy to be performed, under certain circumstances. Purposes of performance Autopsies are performed for either legal or medical purposes. Autopsies can be performed when any of the following information is desired: * Determine if death was natural or unnatural * Injury source and extent on the corpse * Manner of death must be determined * Post mortem interval * Determining the deceas ...

CT Scan
A computed tomography scan (CT scan; formerly called computed axial tomography scan or CAT scan) is a medical imaging technique used to obtain detailed internal images of the body. The personnel that perform CT scans are called radiographers or radiology technologists. CT scanners use a rotating X-ray tube and a row of detectors placed in a gantry (medical), gantry to measure X-ray Attenuation#Radiography, attenuations by different tissues inside the body. The multiple X-ray measurements taken from different angles are then processed on a computer using tomographic reconstruction algorithms to produce Tomography, tomographic (cross-sectional) images (virtual "slices") of a body. CT scans can be used in patients with metallic implants or pacemakers, for whom magnetic resonance imaging (MRI) is Contraindication, contraindicated. Since its development in the 1970s, CT scanning has proven to be a versatile imaging technique. While CT is most prominently used in medical diagnosis, ...

Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from CT and PET scans. MRI is a medical application of nuclear magnetic resonance (NMR) which can also be used for imaging in other NMR applications, such as NMR spectroscopy. MRI is widely used in hospitals and clinics for medical diagnosis, staging and follow-up of disease. Compared to CT, MRI provides better contrast in images of soft-tissues, e.g. in the brain or abdomen. However, it may be perceived as less comfortable by patients, due to the usually longer and louder measurements with the subject in a long, confining tube, though "Open" MRI designs mostly relieve this. Additionally, implants and oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtopsy
Virtopsy is a virtual alternative to a traditional autopsy, conducted with scanning and imaging technology. The name is a portmanteau of "virtual" and "autopsy" and is a trademark registered to Richard Dirnhofer (de), the former head of the Institute of Forensic Medicine of the University of Bern, Switzerland. The term “virtual” in this context apparently is meant in both the modern and original senses. Virtual's Latin root word “virtus” (virtue) implies the qualities of capability, efficiency, effectiveness and objectivity. However, some proponents propose to replace traditional autopsy with this approach. "Virtual" also has the sense of "digital" or refers to virtual reality respectively. Based on Dirnhofer's claim, Virtopsy fully satisfies the requirement that medical forensic findings provide “a complete and true picture of the object examined”. Furthermore, Virtopsy also achieves the objective “that the pathologist’s report should ‘photograph’ with words ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DICOM
Digital Imaging and Communications in Medicine (DICOM) is the standard for the communication and management of medical imaging information and related data. DICOM is most commonly used for storing and transmitting medical images enabling the integration of medical imaging devices such as scanners, servers, workstations, printers, network hardware, and picture archiving and communication systems (PACS) from multiple manufacturers. It has been widely adopted by hospitals and is making inroads into smaller applications such as dentists' and doctors' offices. DICOM files can be exchanged between two entities that are capable of receiving image and patient data in DICOM format. The different devices come with DICOM Conformance Statements which state which DICOM classes they support. The standard includes a file format definition and a network communications protocol that uses TCP/IP to communicate between systems. The National Electrical Manufacturers Association (NEMA) holds the cop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volume Rendering
In scientific visualization and computer graphics, volume rendering is a set of techniques used to display a 2D projection of a 3D discretely sampled data set, typically a 3D scalar field. A typical 3D data set is a group of 2D slice images acquired by a CT, MRI, or MicroCT scanner. Usually these are acquired in a regular pattern (e.g., one slice for each millimeter of depth) and usually have a regular number of image pixels in a regular pattern. This is an example of a regular volumetric grid, with each volume element, or voxel represented by a single value that is obtained by sampling the immediate area surrounding the voxel. To render a 2D projection of the 3D data set, one first needs to define a camera in space relative to the volume. Also, one needs to define the opacity and color of every voxel. This is usually defined using an RGBA (for red, green, blue, alpha) transfer function that defines the RGBA value for every possible voxel value. For example, a volume ma ...

Forensic Pathology
Forensic pathology is pathology that focuses on determining the cause of death by examining a corpse. A post mortem examination is performed by a medical examiner or forensic pathologist, usually during the investigation of criminal law cases and civil law cases in some jurisdictions. Coroners and medical examiners are also frequently asked to confirm the identity of remains. Duties Forensic pathology is an application of medical jurisprudence. A forensic pathologist is a medical doctor who has completed training in anatomical pathology and has subsequently specialized in forensic pathology. The requirements for becoming a "fully qualified" forensic pathologist vary from country to country. Some of the different requirements are discussed below. The forensic pathologist performs autopsies/postmortem examinations with the goal determining the cause of death as well as the possible manner of death. The autopsy report contains conclusions made relating to the following: * The p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
