    en.wikipedia.org/wiki/Single-photon_emission...

    Modern SPECT equipment is available with an integrated X-ray CT scanner. As X-ray CT images are an attenuation map of the tissues, this data can be incorporated into the SPECT reconstruction to correct for attenuation. It also provides a precisely registered CT image, which can provide additional anatomical information.

  3. Radiation treatment planning - Wikipedia

    en.wikipedia.org/wiki/Radiation_treatment_planning

    Doctor reviewing a radiation treatment plan. In radiotherapy, radiation treatment planning (RTP) is the process in which a team consisting of radiation oncologists, radiation therapist, medical physicists and medical dosimetrists plan the appropriate external beam radiotherapy or internal brachytherapy treatment technique for a patient with cancer.

  4. Image-guided radiation therapy - Wikipedia

    en.wikipedia.org/wiki/Image-guided_radiation_therapy

    This form of radiation treatment uses computers and linear accelerators to sculpt a three-dimensional radiation dose map, specific to the target's location, shape and motion characteristics. Because of the level of precision required for IMRT , detailed data must be gathered about tumour locations.

  5. Electron beam computed tomography - Wikipedia

    en.wikipedia.org/wiki/Electron_beam_computed...

    Electron beam computed tomography (EBCT) is a fifth generation computed tomography (CT) scanner in which the X-ray tube is not mechanically spun in order to rotate the source of X-ray photons. This different design was explicitly developed to better image heart structures that never stop moving, performing a complete cycle of movement with each ...

  6. Operation of computed tomography - Wikipedia

    en.wikipedia.org/wiki/Operation_of_computed...

    In conventional CT machines, an X-ray tube and detector are physically rotated behind a circular shroud (see the image above right). An alternative, short lived design, known as electron beam tomography (EBT), used electromagnetic deflection of an electron beam within a very large conical X-ray tube and a stationary array of detectors to achieve very high temporal resolution, for imaging of ...

    SPECT visualized by a MIP of a mouse Types of presentations of CT scans: - Average intensity projection - Maximum intensity projection - Thin slice (median plane) - Volume rendering by high and low threshold for radiodensity.

  8. 4DCT - Wikipedia

    en.wikipedia.org/wiki/4DCT

    Most radiation therapy is planned using the results of a 3D CT scan. A 3D scan largely presents a snapshot of the body at a particular point in time, however due to the time of the acquisition, in which the patient is likely to have moved in some way (even if only breathing), there will be an element of blurring or averaging in the 3D scan.

    3D rendering of a micro CT of a treehopper. 3D rendering of a μCT scan of a leaf piece, resolution circa 40 μm/voxel. Two phase μCT analysis of Ti2AlC/Al MAX phase composite [ 1 ] In radiography , X-ray microtomography uses X-rays to create cross-sections of a physical object that can be used to recreate a virtual model ( 3D model ) without ...
