Ndezvipi zviri kuitika munguva pfupi yapfuura muMedical Imaging?

Kubva pazvakatanga kuma1960 kusvika kuma1980, Magnetic Resonance Imaging (MRI), computerized tomography (CT) scans, uye positron emission tomography (PET) scans zvakafambira mberi zvikuru. Zvishandiso izvi zvekurapa zvisingapindike zvakaramba zvichichinja nekubatanidzwa kwehungwaru hwekugadzira (AI), matekiniki akawedzerwa ekuunganidza data raw, uye multi-parametric statistical analysis, zvese izvi zvinobatsira mukuvandudza kunzwisisa nekuongorora masisitimu edu emukati.

Kuvandudzwa kwePET neCT scans

Kuongororwa kwePET kwakajairika kunowanzo tora pakati pemaminitsi makumi mana nemashanu neawa imwe chete kuti kupedzwe uye kunogona kugadzira mifananidzo yakasiyana yekukura kwegomarara muuropi, mapapu, muromo wechibereko, nedzimwe nzvimbo dzemuviri. Kufambira mberi kuri kuitika kwakawedzera kushanda kwenzira iyi, kusanganisira software yekugadzirisa kusanzwisisika kwemafambiro uye kugonesa kuongororwa kwealgorithmic kufanoona nzvimbo yegomarara mukati menyama inofamba.

Kukanganisika kwemafambiro kunoitika kana chikamu chechinangwa chichifamba panguva yekutora mufananidzo wePET scan, zvichiita kuti zviomere kuongorora nekuongorora huwandu hwezvinhu kana kuti tissue. Kuti vaderedze kufamba panguva yePET scan, nyanzvi dzezvehutano dzinoshandisa gated acquisition, vachikamura scanning cycle kuita "mabin" akawanda. Nekupatsanura maitiro ekuskena kuita mabin 8-10, chirongwa ichi chinogona kufanoona nzvimbo yehuwandu hwezvinhu panguva chaiyo kana nzvimbo, zvichibva pane zvinodiwa nemushandisi. Kufanotaura uku kunoitwa nekufungidzira nzvimbo yehuwandu hwezvinhu mukati memabin ega ega edenderedzwa. Maitiro ekupenda PET gated anoderedza kukanganisika kwemafambiro ari mumudziyo, zvichikonzera kuvandudzwa kwehuwandu hwemabasa/kugadziriswa kwakajairwa (SUV). Kana data rePET rakabatana nedata reCT, maitiro ese anozivikanwa se4D CT scanning.

Kunyange zvakadaro, pane muganho unozivikanwa une chekuita nemaitiro aya. Kushandisa nzira dzakavharirwa dzekutora mifananidzo kunokonzera ruzha rwakawanda nekuda kwekuwana data rakawanda. Nzira dzakasiyana-siyana dzekugadzirisa dambudziko iri dzinosanganisira Q-freeze, Oncofreeze, uye nguva yekubhururuka (ToF).

Kugadziriswa kwekusajeka kwemifananidzo mukati mePET neCT scans

Kugadzirisa mifananidzo kwakavakirwa paQ-freeze, uchishandisa gated acquisition, kunosanganisira kuunganidzwa nekunyoreswa kwemifananidzo yese yakagadzirwa. Kunyoresa uku kunoitika munzvimbo yemufananidzo, kuunganidza nekugadzirazve data rese rakawanikwa kubva kuPET scan kuti pave nemufananidzo wekupedzisira usina ruzha rwakanyanya uye kusviba.

OncoFreeze, nzira yesoftware yekutarisa, inofanana neQ-freeze mune dzimwe nzira, kunyangwe zvakasiyana zvachose. Kugadziriswa kwemafambiro kunoitwa munzvimbo ye sinogram (nzvimbo yedata isina kurongeka). Mushure mekuwana mufananidzo wekutanga, mifananidzo inotevera isina kujeka inotaridzwa mberi uye inoenzaniswa nedata rakatarwa rebenchi rekuvhiya uye ratios dze sinogram dze backproject. Izvi zvinotungamira kumufananidzo wekupedzisira wakagadziridzwa zvichibva pamufananidzo wekugadzirisa wakabviswa.

Kubata mafungu ekufema panguva yekuskena kwePET pamwe chete neCT scans kunogona kutungamira mukuvandudzwa kwemhando yemufananidzo. Kunatsiridza kurongeka kunogona kuratidzwa nekubatanidza mafungu ePET scans, nzira yakajairika, nemafungu eCT scans, nzira ichangobva kugadzirwa.

Sezvatinoziva tese, kukura kweindasitiri yemifananidzo yezvokurapa hakuparadzaniswi nekugadzirwa kwemidziyo yekurapa yakatevedzana - majekiseni ekudzivirira emhando dzakasiyana-siyana uye zvinodyiwa zvinotsigira - zvinoshandiswa zvakanyanya mundima iyi.
