Assessment of methods for volumetric quantification of intracerebral hematomas in computerized tomography images
(Sociedad Venezolana de Farmacología Clínica y Terapéutica, 2018)
This work evaluates the performance of computational methods
aimed at volume generation of five intracerebral hematomas
(ICH), present in multi-layer computed tomography
images, by means of three complementary steps. First. A
ground truth volume or reference volume (RV) is considered.
This RV is obtained, by a neurosurgeon, using the manual
planimetric method (MPM). In a second step, the volumetry
of the 5 ICH’s is obtained considering both the original version
of the ABC/2 method and two of its variants, identified in
this paper as ABC/3 ...
Volumetry of subdural hematomas in computed tomography images: ABC methods versus an intelligent computational technique
(Sociedad Venezolana de Farmacología Clínica y Terapéutica, 2018)
This work evaluates the performance of some methods oriented
towards the generation of the volume of four subdural
hematomas (SDH), present in multi-layer computed tomography
images. To do this, firstly, a reference volume is specified:
the volume obtained by a neurosurgeon using the manual
planimetric method (MPM); which allows the generation of
manual segmentations of space-occupying lesions. In this
case, these volumes are matched with the SDH. In parallel,
the volumetry of the 4 SDHs is obtained, considering both the
original version ...
Volumetry of epidural hematomas in computed tomography images: Comparative study between linear and volumetric methods
(Sociedad Latinoamericana de Hipertensión, 2018)
This work evaluates the performance of some
methods employed for assessing the volume of
seven subdural hematomas (EDH), present in
multi-layer computed tomography images. Firstly, a reference
volume is considered to be that obtained by a neurosurgeon
using the manual planimetric method (MPM).
Secondly, the volume of the 7 EDHs is obtained considering
both the original version of the ABC/2 method and two of
its variants, identified in this paper as ABC/3 method and
2ABC/3 method. The ABC methods allow for calculation
of the volume of ...
