Summary<\/h2>

\"These<\/span> <\/span><\/p>

This dataset was derived from tracked biopsy sessions using the Artemis biopsy system, many of which included image fusion with MRI targets. Patients received a 3D transrectal ultrasound scan, after which nonrigid registration (e.g. \u201cfusion\u201d) was performed between real-time ultrasound and preoperative MRI, enabling biopsy cores to be sampled from MR regions of interest.\u00a0Most cases also included sampling of systematic biopsy cores using a 12-core digital template.\u00a0The Artemis system tracked targeted and systematic core locations using encoder kinematics of a mechanical arm, and recorded locations relative to the Ultrasound scan. MRI biopsy coordinates were also recorded for most cases.\u00a0STL files and biopsy overlays are available and can be visualized in\u00a0<\/span>3D Slicer<\/a>\u00a0with the\u00a0<\/span>SlicerHeart extension<\/a>.\u00a0 Spreadsheets summarizing biopsy and MR target data are also available.\u00a0<\/span>See the Detailed Description tab below for more information.<\/span><\/p>

MRI targets were defined using multiparametric MRI, e.g. t2-weighted, diffusion-weighted, and perfusion-weighted sequences, and scored on a Likert-like scale with close correspondence to PIRADS version 2. t2-weighted MRI was used to trace ROI contours,<\/span>\u00a0and is the only sequence provided in this dataset. MR imaging was performed on a 3 Tesla Trio, Verio or Skyra scanner (Siemens, Erlangen, Germany). A transabdominal phased array was used in all cases, and an endorectal coil was used in a subset of cases. The majority of pulse sequences are 3D T2:SPC, with TR\/TE 2200\/203, Matrix\/FOV 256 \u00d7 205\/14 \u00d7 14 cm, and 1.5mm slice spacing. Some cases were instead 3D T2:TSE with TR\/TE 3800\u20135040\/101, and a small minority were imported from other institutions (various T2 protocols.)<\/span><\/p>

Ultrasound scans were performed with Hitachi Hi-Vision 5500 7.5 MHz or the Noblus C41V 2-10 MHz end-fire probe. 3D scans were acquired by rotation of the end-fire probe 200 degrees about its axis, and interpolating to resample the volume with isotropic resolution.<\/p>

Patients with suspicion of prostate cancer due to elevated PSA and\/or suspicious imaging findings were consecutively accrued. Any consented patient who underwent or had planned to receive a routine, standard-of-care prostate biopsy at the UCLA Clark Urology Center was included.\u00a0 \u00a0<\/p>

Note<\/strong>: Some Private Tags in this collection are critical to properly displaying the STL surface and the Prostate anatomy.\u00a0 Private Tag\u00a0(1129,"Eigen Artemis",1016) DS VoxelSize is especially important for multi-frame US cases.<\/span> \u00a0 \u00a0<\/p>
