	'''Focal plane tomography''' is a ~~medical imaging~~ technique ~~that allows for the visualization~~ of specific ~~planes within the body by~~ blurring out structures ~~that are not~~ in ~~the plane of interest~~. This ~~technique~~ is particularly useful in ~~radiology~~ for ~~examining~~ complex anatomical structures ~~and is often used in dental and maxillofacial imaging~~.		'''Focal plane tomography''' is a radiographic technique used to obtain clear images of specific layers or "slices" of an object, while blurring out structures in other planes. This method is particularly useful in medical imaging, where it allows for the detailed examination of complex anatomical structures by isolating a particular plane of interest.

	== Principles of Focal Plane Tomography ==		== Principles of Focal Plane Tomography ==

	~~Focal~~ plane tomography ~~operates on~~ the ~~principle of~~ synchronized movement ~~between~~ the X-ray source and the film or detector~~. As the X-ray tube moves in one direction, the film moves~~ in ~~the~~ opposite ~~direction~~. This ~~coordinated~~ movement ensures that only structures in ~~a specific~~ plane remain ~~in focus~~, while ~~structures~~ above and below ~~this plane~~ become blurred~~. This selective blurring enhances~~ the ~~visibility of the focal plane, allowing for detailed examination of the area of interest~~.		The fundamental principle of focal plane tomography involves the synchronized movement of the X-ray source and the film or detector in opposite directions around a fixed fulcrum. This movement ensures that only the structures in the focal plane remain sharp, while those above and below it become blurred due to the relative motion.

	~~== Applications ==~~		The degree of blurring is determined by the distance from the focal plane, with structures further away appearing more blurred. This selective focusing is achieved by adjusting the angle and speed of the movement, allowing for precise imaging of the desired plane.

	~~Focal plane tomography is widely used~~ in ~~various medical fields, including:~~		== Applications in Medical Imaging ==

	* '''Dentistry''': It is used ~~to obtain detailed images of the teeth and jaw~~, ~~aiding~~ in the ~~diagnosis~~ of ~~dental conditions and planning of dental procedures.~~		Focal plane tomography has been widely used in various medical imaging applications, particularly in the fields of [[dentistry]], [[orthopedics]], and [[pulmonology]].
	* '''Orthopedics''': It helps in visualizing complex bone structures and joints, ~~assisting in the diagnosis of fractures~~ and ~~other orthopedic conditions.~~
	* '''Oncology''': It can be used to detect and monitor tumors by providing clear images of specific tissue planes.

	== ~~Advantages~~ and ~~Limitations~~ ==		=== Dentistry ===

			In dentistry, focal plane tomography is employed to obtain detailed images of the teeth and jaw structures. This technique is particularly useful for assessing the condition of the [[temporomandibular joint]] and for planning complex dental procedures.

			=== Orthopedics ===

	~~=== Advantages ===~~		In orthopedic imaging, focal plane tomography aids in the evaluation of bone structures and joint spaces. It is often used to assess fractures, bone lesions, and the alignment of bones in the [[skeletal system]].

	* '''Enhanced Visualization''': By focusing on a specific plane, focal plane tomography provides clearer images of the area of interest.		=== Pulmonology ===
	* '''Reduced Superimposition''': It minimizes the overlap of structures, which is a common issue in conventional radiography.

	~~=== Limitations ===~~		In pulmonology, this technique is used to visualize the [[lungs]] and surrounding structures. It helps in the diagnosis of conditions such as [[tuberculosis]], [[pneumonia]], and [[lung cancer]] by providing clear images of the lung parenchyma and airways.

	* '''Limited Depth''': Only one plane is in focus at a time, which may require multiple images to fully assess a region.		== Advantages and Limitations ==
	* '''Radiation Exposure''': As with all X-ray based techniques, there is exposure to ionizing radiation, which must be minimized.

	~~== Technological Developments ==~~		Focal plane tomography offers several advantages, including the ability to focus on specific anatomical planes and reduce the superimposition of structures. This results in clearer images of the area of interest, which can be crucial for accurate diagnosis and treatment planning.

	~~With advancements in imaging technology~~, ~~focal plane tomography~~ has ~~evolved~~. ~~Modern techniques~~ such as [[computed tomography]] (CT) and [[magnetic resonance imaging]] (MRI) ~~have largely supplanted traditional~~ tomography in ~~many applications due to their ability to provide three-dimensional images~~ and ~~greater detail~~.		However, the technique also has limitations. It requires precise equipment and skilled operators to achieve optimal results. Additionally, with the advent of more advanced imaging modalities such as [[computed tomography]] (CT) and [[magnetic resonance imaging]] (MRI), the use of focal plane tomography has declined in favor of these more comprehensive and detailed imaging techniques.

	* [[Tomography]]		Focal plane tomography remains a valuable tool in specific clinical scenarios where detailed imaging of a particular plane is required. Despite being overshadowed by more advanced imaging technologies, it continues to be used in certain fields due to its unique ability to isolate and clarify specific anatomical structures.
