Syntax

[XLim,YLim,ZLim] = sliceLimits(medVol,slice,direction)

Description

[XLim,YLim,ZLim] = sliceLimits(medVol,slice,direction) extracts the X-, Y-, and Z-limits for one slice, slice, in the specified direction direction of the medicalVolume object medVol. The slice limits are in the patient coordinate system.

Open Live Script

Get the limits for one slice of a medical volume created using a chest CT volume saved as a directory of DICOM files. The CT volume is part of a data set containing three CT volumes. The size of the entire data set is approximately 81 MB. Download the data set from the MathWorks® website, then unzip the folder.

zipFile = matlab.internal.examples.downloadSupportFile("medical","MedicalVolumeDICOMData.zip");
filepath = fileparts(zipFile);
unzip(zipFile,filepath)

Specify the directory of DICOM files for the first CT volume in the data set.

dataFolder = fullfile(filepath,"MedicalVolumeDICOMData","LungCT01");

Create a medical volume object for the CT volume.

medVol = medicalVolume(dataFolder);

Extract the x-, y-, and z-axis limits, in millimeters, of the second slice in the coronal direction.

[XLim,YLim,ZLim] = sliceLimits(medVol,2,"coronal")
XLim = 1×2

 -186.5000  185.7717


YLim = 1×2

 -185.7715 -185.7715


ZLim = 1×2

 -281.2500  -63.7500

Input Arguments

collapse all

Medical volume, specified as a medicalVolume object.

Slice index, specified as a positive integer scalar in the range [1, numSlices], where numSlices is the number of slices in the volume along the direction specified by direction.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | logical

Direction along which to extract the slice limits, specified as "coronal", "sagittal", or "transverse".

Data Types: char | string

Output Arguments

collapse all

Limits of the volume in the x-dimension of the patient coordinate system, returned as a 2-element numeric vector of the form [xMin xMax]. The limits are in the units specified by the SpatialUnits property of medVol.

Limits of the volume in the y-dimension of the patient coordinate system, returned as a 2-element numeric vector of the form [yMin yMax]. The limits are in the units specified by the SpatialUnits property of medVol.

Limits of the volume in the z-dimension of the patient coordinate system, returned as a 2-element numeric vector of the form [zMin zMax]. The limits are in the units specified by the SpatialUnits property of medVol.
