Normal anatomy of the brain can be studied by comparing CT slices in three planes : horizontal, frontal and sagittal. Most present devices allow horizontal sections ; frontal sections can be obtained with some devices either directly or by reconstruction ; sagittal slices are obtained only by ...
This photo gallery presents the anatomy of the abdomen by means of CT (axial, coronal, and sagittal reconstructions). Axial view Coronal view Sagittal view Abdominal Computed Tomography Abdominal computed tomography (CT) is a type of medical imaging procedure used to diagnose and monitor internal ...
One major difference between chest CT and abdominal CT is that the pancreatic and lesion regions are sometimes partially scanned in chest CT, depending on the different scanning ranges of the protocol and the anatomy of the patient. This difference could induce domain shift issues for machine learn...
it facilitates a single imaging session without the need for a second CT or subsequent scan. Secondly, it enables voxelwise alignment, providing true spatial multiplexing. This capability is crucial for understanding the spatial heterogeneity of tumours, as the multiplexed image can simultaneously high...
51 More accurate non-invasive characterization of anatomy through increased spatial resolution could mitigate these hurdles. 4.4. Can UHRCT improve monitoring of anti-atherosclerotic therapies and microvascular disease in the heart and other organ systems? Novel therapies to reduce plaque formation over ...

From those protocols, organ dose were estimated using a CT dosimetry method based on Monte Carlo radiation transport (Lee et al, 2012), which is reported to provide more accurate estimations than older numerical tools, as the body contour and internal anatomy of patients are described by ...
as low as 10 ms. In 1984, electron beam computed tomography (EBCT) was introduced as a noninvasive imaging modality for the diagnosis of coronary artery disease (1–4). Its temporal resolution of 100 ms allows for relatively motion-free imaging of the cardiac anatomy in the diastolic phase,...
