Objective (s): Various iterative reconstruction algorithms in nuclear medicine have been introduced in the last three decades. For each new imaging system, it is wise to select appropriate image reconstruction algorithms and evaluate their performance. In this study, three approaches of image reconstruction were developed for a novel desktop open-gantry SPECT system, PERSPECT, to assess their p...

background anterior cruciate ligament (acl) injury is the most common sports injury in both athletes and nonathletes; it can cause disability if not treated correctly. in cases with minor injuries, conservative treatments suffice. but, in cases with acl tear, surgery by different methods and autografts are indicated. the most prevalent method for acl reconstruction is the use of hamstring tendo...

reconstruction of breast with transverse rectus abdominis myocutaneous (tram) flap is the standard for reconstruction of breast following mastectomy. in this article, authors report their experience with pedicled tram flap reconstruction of the breast. records for the patients who had undergone breast reconstruction with pedicled tram flap were retrieved. records of outpatient follow-ups were a...

this study was designed reevaluate the outcome of soft wall reconstruction technique for cwd mastoidectomy and to test the validity of anteriorly–based musculoperiosteal flap attachment without oblitrating the mastoid cavity for increasing graft viability. two methods of reconstruction were used. soft wall reconstruction method as described previously by smith et al, were performed on 35 patien...

 ABSTRACT Background: The transverse rectus abdominis musculocutaneous (TRAM) flap remains the gold standard for postmastectomy reconstruction either immediate or delayed. However, transfer of TRAM flap can be associated with donor site morbidities and complications in flap. A successful reconstruction consists of careful patient selection, surgical technique and meticulous preoperative plannin...

Abstract Dental calculus and other preserved microbiome substrates are an attractive target for dietary reconstruction in past populations through a variety of physical, chemical, molecular means. Recently, studies have attempted to reconstruct diet from archaeological dental using archaeogenetic techniques. While may provide relatively stable environment DNA preservation, the detection plants ...

A minimal variance reconstruction scheme is derived using derivatives of the Gaussian as filters. A closed form mixed correlation matrix for reconstructions from multiscale points and their local derivatives up to the second order is presented. With the inverse of this mixed correlation matrix, a reconstruction of the image can be easily calculated. Some interesting results of reconstructions f...

experiences indicate that after earthquakes a little attention is paid to the role of collective memory (cm) in the reconstruction process. this is due to time constraints, because all organizations try to speed up the physical reconstruction process, after the disasters. thus, quality is sacrificed for quantity. herein one of the most challenging issues is the reconstruction of bazaar neighbor...
