Digital Autopsy
A Virtual Autopsy is a non-invasive autopsy in which digital imaging technology, such as with computerized tomography (CT) or magnetic resonance imaging (MRI) scans, is used to develop three-dimensional images for a virtual exploration of a human body. Virtual 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 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 Virtual Autopsy. The term cannot be found before 1980 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 One of the first ...

Autopsy
An autopsy (also referred to as 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 the exam may be performed to evaluate any disease or injury that may be present for research or educational purposes. The term ''necropsy'' is generally used for non-human animals. Autopsies are usually performed by a specialized medical doctor called a pathologist. Only a small portion of deaths require an autopsy to be performed, under certain circumstances. In most cases, a medical examiner or coroner can determine the cause of death. Purposes of performance Autopsies are performed for either legal or medical purposes. Autopsies can be performed when any of the following information is desired: * Manner of death must be determined ** Determine if death was natural or unnatural ** Injury source and extent on the corpse * Pos ...

CT Scan
A computed tomography scan (CT scan), formerly called computed axial tomography scan (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, i ...

Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from computed tomography (CT) and positron emission tomography (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, although ...

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, the former head of the Institute of Forensic Medicine of the University of Bern, Switzerland. Dirnhofer has proposed virtopsy as a partial or complete replacement for traditional autopsy, and he has asserted that virtopsy fully satisfies the requirement that medical forensic findings provide “a complete and true picture of the object examined”. Furthermore, virtopsy is said to achieve the objective “that the pathologist’s report should ‘photograph’ with words so that the reader is able to follow his thoughts visually”. Concept Virtopsy employs imaging methods that are also used in clinical medicine such as computed tomography (CT) scans and magnetic resonance imaging (MRI). Also, 3D body surface scanning is used to integrate body surface documentation w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DICOM
Digital Imaging and Communications in Medicine (DICOM) is a technical standard for the digital storage and Medical image sharing, transmission of medical images and related information. It includes a file format definition, which specifies the structure of a DICOM file, as well as a network communication protocol that uses Internet protocol suite, TCP/IP to communicate between systems. The primary purpose of the standard is to facilitate communication between the software and Computer hardware, hardware entities involved in medical imaging, especially those that are created by different manufacturers. Entities that utilize DICOM files include components of Picture archiving and communication system, picture archiving and communication systems (PACS), such as Modality (medical imaging), imaging machines (modalities), Radiological information system, radiological information systems (RIS), Image scanner, scanners, Printer (computing), printers, Server (computing), computing servers, a ...

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 volu ...

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 (see ''§ Education''). The forensic pathologist performs autopsies/postmortem examinations with the goal of determining the cause of death as well as the possible manner of death. The autopsy report contains conclusions made ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
