Field Documentation

unsigned short int*** PRMAT::_factdata

Hidden pointer for the actual data.

unsigned int** PRMAT::_linesdata

Hidden pointer for the actual data.

int PRMAT::binNr

Scanner geometrics, field binNr.

int* PRMAT::dime

Number of pixels hit by a line for every line.

int PRMAT::dimr

Dimension of rows (lines of response) in the projection matrix.

unsigned short int*** PRMAT::fact

Coordinates and factors of pixels hit by a line of response. fact[row][pix][0]=x-coordinate && fact[row][pix][1]=y-coordinate && fact[row][pix][2]=factor.

float* PRMAT::factor_sqr_sum

Square sums of factors in each row in the projection matrix.

float PRMAT::factor_sum

The sum of all factors in the projection matrix.

int PRMAT::imgDim

Scanner geometrics, field imgDim.

unsigned int** PRMAT::lines

Coordinates of a pixel, number of lines of response intersecting the pixel and the coordinates of coincidence lines (nrp x (lines + 2) array). lines[row][0] = pixel coordinates , lines[row][1] = lines hitting a pixel.

float PRMAT::max

Maximal factor value in the projection matrix.

float PRMAT::min

Minimal factor value in the projection matrix.

int PRMAT::mode

Discretisation model utilised.

int PRMAT::nrp

Number of pixels inside the fov. i.e. number of rows in the look-up table.

int* PRMAT::prmatfov

FOV of the projection matrix. prmatfov[0]=major semiaxe, prmatfov[1]=minor semiaxe.

float PRMAT::scaling_factor

Scaling factor for factors (notice that factors are stored in integers).

char PRMAT::status

Prmat status.

char PRMAT::type

Scanner information on the prmat. 0=ECAT931 1=GE Advance.

int PRMAT::viewNr

Scanner geometrics, field viewNr.
