While brachytherapy is the oldest form of radiation therapy, it is also a very exciting field from both physics and clinical perspectives. From the physics standpoint, brachytherapy dosimetry is largely being governed by the inversesquare law, leading to an unparalleled dose deposition kernel (dose emitted by a seed or single dwell position), even compared to proton or heavy-ion beamlets. There is slightly more dose beyond the central deposition point, but comparatively very little prior to it, that is, little or no entrance dose! It is easy to sum multiple dwell positions that cover a tumor, and the intensity can be modulated quite effectively using dwell times. From a clinical perspective, what sets brachytherapy apart from other intraoperative modalities (e.g., laser, radiofrequency, cryogenic) is our ability to precisely calculate the energy deposited across the relevant patient geometry, anticipate the effect from known dose-outcome relationships, and deliver that energy with exquisite control and selectively to the target volume while sparing organs at risks. This targeting ability has improved substantially over the last two decades. It is built upon key foundational elements, many of which stem from the research and development within our medical physics community.This article provides an overview of these elements that combine to make brachytherapy a successful and developing radiotherapy modality.

“…Based upon some of our early primitive experiments with biplane scanning of the prostate, the B & K Company developed a multiplane scanner with built-in puncture facilities [48]. We decided to use a multiplane rectal scanner for ultrasound-guided seed implantation because the depth of the implantation could then be monitored continuously [49]. The rectal probe is mounted in a fixture attached to the table (Fig.…”

The history of interstitial brachytherapy of the prostate began in 1917 when Barringer inserted radium needles transperineally into the prostate, guided by a finger in the rectum. In 1952, Flocks et al. Injected radioactive gold solution in prostatic cancer during open operation. In 1972, Whitmore et al. Described retropubic Iodine‐125 seed implantation through an open operation with pelvic lymph node dissection. The basis for ultrasound (US)‐guided seed implantation was established in the late 1960s by Kratochwil's description of the first puncture transducer for one‐dimensional US‐guidance and Watanabe's pioneer work in prostatic screening. Our group performed the first punctures guided by static two‐dimensional ultrasonic scanning (1969) and by dynamic ultrasound scanning (1974). During the 1970s, US‐guided biopsies of almost all abdominal organs were performed and, in 1981, we introduced US‐guided seed implantation of abdominal tumors and developed a technique for precise needle placement in the prostate guided by transrectal ultrasound. This was followed in 1983 by a technique for seed implantation guided by transrectal (transverse) ultrasonic scanning. That same year, Fornage described prostatic biopsy guided by transrectal longitudinal scanning. In 1990, we developed the seed implantation technique further by combining transverse and longitudinal scannings. In the late 1980s, Ragde from Seattle transferred the technique to the U.S., and since then, Ragde, Blasko, and others have treated numerous patients, refined the technique, taught many courses, and published extensively. They have obtained very promising prostate‐specific antigen (PSA)‐based results which compare favorably with radical prostatectomy and external beam radiation in the treatment of prostatic cancer.

“…The ultrasound system was further refined with the ability of multiplane scanning allowing a continuous longitudinal view and making depth perception technically easier. 20,21 This meant that cranial-caudal movements of the prostate such as those that occur when a needle is inserted, could potentially be accounted for within the operating room. 22 With refinements in computer software and radiophysics, the technique has become known as the 'Seattle technique'.…”

Purpose: To summarise the practical aspects of the development of techniques of interstitial permanent prostate brachytherapy (PPB) implantation. Prostate brachytherapy dates back to Pasteau's publication in 1913 describing the insertion of a radium capsule into the prostatic urethra to treat carcinoma of the prostate. Various implantation methods were employed but with unsatisfactory results until the development of the transrectal ultrasound in the 1980s. The subsequent two-stage Seattle technique allowed for a planned homogenous distribution of radioactive sources throughout the gland resulting in biochemical control comparable to surgical and external beam radiotherapy series. With the advent of advanced computer software and improved imaging, the technique has developed accordingly to a single stage procedure with ontable dosimetric assessment. The principles of targeting dose to the prostate while avoiding surrounding organs at risk remain as relevant today as nearly a century ago. There is an array of techniques to consider for the novice PPB provider. Whether the evolution of PPB techniques will translate into improved biochemical control is yet to be seen.
